GPIB Programming with
Agilent 89400-Series Analyzers
1
Introduction to GPIB Programming
Introduction to GPIB Programming
For an introduction to GPIB programming, read the GPIB Programmer’s Guide. It is provided to
help those not familiar with GPIB programming or remote control of an instrument. The book
introduces the basic concepts of GPIB programming and describes the Standard Commands for
Programmable Instruments (SCPI). It also describes how to operate an instrument in an GPIB
system and how to transfer data between an external controller and an instrument.
In This Book
This is the GPIB Command Reference for the Agilent 89400-Series Vector Signal Analyzer. It
contains the command syntax, structure, and a detailed description of each GPIB command
available for the Agilent 89400-Series analyzers.
Chapter 1 presents GPIB programming information specific to the analyzer:
How to connect the analyzer to an external controller and verify that it works.
A description of the analyzer’s status registers.
Chapter 2 describes the SCPI instrument model.
Chapter 3 is the command reference. It contains a detailed description of each GPIB command.
The commands are organized alphabetically.
Appendix A discusses SCPI error messaging and lists error messages reported by this instrument.
Appendix B is an example program listing which demonstrates the sockets feature of option UFG.
Also, a card containing a command quick-reference is included.
Note
2
Most front-panel key presses that change the configuration or initiate an action
correspond to one SCPI command but some require more than one (see
[SENSe:]AVERage:TYPE). To display the SCPI command strings that correspond
to front-panel keys, activate the SCPI command echo by pressing [ Local/Setup ],
[ SCPI cmd echo on ] or sending “SYST:GPIB:ECHO 1”. Subsequent SCPI command
strings are displayed in the upper-lefthand corner of the display.
GPIB Setup and Verification
GPIB Setup and Verification
This section contains a procedure for configuring the Agilent 89400-Series Vector Signal Analyzer
and an external controller in a simple GPIB system. Although an HP 9000 Series 340 computer is
used in this procedure example, other computers that support an GPIB interface can be used. If
you are using a computer other than the Series 340, the configuration procedure should be used
as a general guide. Consult your computer’s documentation for more complete information.
Equipment and Software Required
Agilent 89400-Series Vector Signal Analyzer
HP 9000 Series 340 computer
GPIB cable (Agilent 10833A, B, C or D)
Agilent Technologies BASIC programming language
Procedure
1. Turn off the analyzer and the HP 9000 Series 340
2. Connect them with the GPIB cable.
3. Turn on the computer. If necessary, load BASIC. Note that the following language
extensions must be installed for the verification program to work:
CRTA
HPIB
IO
EDIT
Programs that are more complex than the verification program may require more language
extensions. For a complete list of loaded language extensions, execute the BASIC
command:
LIST BIN
4. Turn on the analyzer. When the startup processes are complete, press the [Local/Setup]
hardkey.
5. Verify that the analyzer’s address is set to 19. The current address setting is displayed in the
[analyzer adrs] softkey. You can change the address by pressing the [analyzer adrs] softkey, entering
the number using the numeric keypad, and then pressing the [enter] softkey. Instructions in
the verification procedure assume that the analyzer address is set to 19.
6. Verify that the analyzer is set to the addressable-only mode. The softkey labels that appear
when you press the [Local /Setup] hardkey include [system controller] and [addressable only]. Only one of
these two softkeys can be selected at a time, and the one that is selected is highlighted with
yellow text. If [addressable only] is not selected, then press its softkey.
7. Type REMOTE 719 on the computer and press Enter. The Remote indicator (near the
[Local/Setup] hardkey) should light up. This indicates that the analyzer is in remote control.

General Status Register Model
General Status Register Model
Overview
The general status register model, shown in figure 1, is the building block of the analyzer’s status
system. Most register sets in the analyzer include all of the registers shown in the general model,
although commands are not always available for reading or writing a particular register. The
information transfer within a register set starts at the condition register and ends at the register
summary bit (see figure 2). The information is controlled by altering bits in the transition and
enable registers.
Figure 1. General Model of a Status Register Group
When a status group is implemented in a SCPI instrument, it always contains all of the component
registers. There is not always a corresponding command to read or write every register, however.
The flow within a status group starts at the condition register and ends at the register summary
bit as shown in figure 2. You control the flow by setting the bit patterns in the transition and
enable registers.
Figure 2. Flow of Information Within a Register Set

General Status Register Model
Condition Register
Condition registers continuously monitor hardware and firmware status. They represent the
current state of the instrument. Bits in a condition register are not latched or buffered. They are
updated in real time. When the condition monitored by a particular bit becomes true, the bit is set
to 1. When the condition becomes false, the bit is reset to 0. Condition registers are read-only.
Transition Registers
Transition registers control the reporting of condition changes to the event registers. They
specify which types of changes in the condition register set corresponding bits in the event
register. Transition registers are read-write.
Transition register bits may be configured to signal positive changes, negative changes, or both.
Positive changes in the state of a condition bit (0 to 1) are reported to the event register if the
corresponding positive transition bit is set to 1. Negative changes in the state of a condition bit (1
to 0) are reported to the event register if the corresponding negative transition bit is set to 1. If
you set both transition bits to 1, positive and negative changes are reported to the corresponding
event bit.
Transition registers are not affected by *CLS (clear status) or queries. They are set to default
values when power is turned on and after receiving *RST. Some registers have a fixed setting if
there are no commands to access a particular transition register. This fixed setting, along with
dependent values, are specified in the GPIB Command Reference.
Event Register
Event registers latch any reported condition changes. When a transition bit allows a condition
change to be reported, the corresponding event bit is set to 1. Once set, an event bit is no longer
affected by condition changes. It remains set until the event register is cleared— either when you
read the register or when you send the *CLS (clear status) command. Event registers are
read-only.
Notes
6
Reading the Event Register, clears the Event Register.
All event registers are cleared by the *CLS command.
General Status Register Model
Enable Register
Enable registers control the reporting of events (which are latched condition register information)
to the register summary bit. If an enable bit is set to one, the corresponding event bit is included
in the logical ORing process that determines the state of the summary bit. (The summary bit is
only set to 1 if one or more enabled event bits are set to 1.) You can read and write all enable
registers.
Enable registers are cleared by the *CLS (clear status) command. Querying enable registers does
not affect them. All enable registers have commands to read and write them.
An Example Sequence
The example illustrated in figure 3 presents four different cases, as defined by the settings in the
leftmost block; each row contains a slightly different variation of the sequence as defined by the
settings of the transition and enable registers. The changing state of the condition in question is
shown at the bottom of the figure. A small binary table shows the state of the chosen bit in each
status register at selected times (T1–T5). There are two ‘’events’’ or changes in the condition
being monitored that cause register values to change. There are also three reads of the event
register (indicated with asterisks), which clear it.
Figure 3. Example Sequence
In cases A and D, when the enable bit is zero, the summary bit cannot be set, regardless of the
transition register settings, and no service request is made. When the enable bit is one, the
summary bit is set when the transition occurs for which the corresponding transition register is
configured to report.

General Status Register Model
How to Use Registers
There are two methods you can use to access the information in status registers:
The polling method.
The service request (SRQ) method.
In the polling method, the analyzer has a passive role. It only tells the controller that conditions
have changed when the controller asks the right question. In the SRQ method, the analyzer takes
a more active role. It tells the controller when there has been a condition change without the
controller asking. Either method allows you to monitor one or more conditions.
The polling method works well if you do not need to know about changes the moment they occur.
The SRQ method should be used if you must know immediately when a condition changes. To
detect a change using the polling method, the program must repeatedly read the registers.
Use the SRQ method when:
–
–
–
–
you need time-critical notification of changes
you are monitoring more than one device which supports SRQs
you need to do have the controller do something else while waiting
you can’t afford the performance penalty inherent to polling
Use polling when:
– your language/development environment does not support SRQ interrupts
– you want to write a simple, single-purpose program and don’t want the added complexity
of setting up an SRQ handler.
To monitor a condition:
1. Determine which register contains the bit that reports the condition.
2. Send the unique GPIB query that reads that register.
3. Examine the bit to see if the condition has changed.
8
The Service Request Process
The Service Request Process
When you monitor a condition with the SRQ method, you must:
1. Determine which bit monitors the condition.
2. Determine how that bit reports to the request service (RQS) bit of the Status Byte.
3. Send GPIB commands to enable the bit that monitors the condition and to enable the
summary bits that report the condition to the RQS bit.
4. Enable the controller to respond to service requests.
When the condition changes, the analyzer sets its RQS bit and the GPIB’s SRQ line. The controller
is informed of the change as soon as it occurs. The time the controller would otherwise have used
to monitor the condition can now be used to perform other tasks. Your program determines how
the controller responds to the SRQ.
Generating a Service Request
To use the SRQ method, you must understand how service requests are generated. As shown in
figure 4, other register sets in the analyzer report to the Status Byte. Most of them report directly,
but three report indirectly—via the Questionable Status register set (see figure 5).
Figure 4. Generating a Service Request
Bit 6 of the Status Byte serves two functions; the request service function (RQS) and the master
summary status function (MSS). The RQS bit is set whenever something (that it is configured to
report) changes and is cleared when the status byte is read (with a serial poll). The MSS bit is set
in the same way as the RQS bit, but it clears only when the condition that set it is cleared. The
MSS bit is read with *STB?.
9
The Service Request Process
When a register set causes its summary bit in the Status Byte to change from 0 to 1, the analyzer
can initiate the service request (SRQ) process. However, the process is only initiated if both of
the following conditions are true:
The corresponding bit of the Service Request Enable register is also set to 1.
The analyzer does not have a service request pending. (A service request is considered to be
pending between the time the analyzer’s SRQ process is initiated and the time the controller
reads the Status Byte register with a serial poll.)
The SRQ process sets the GPIB’s SRQ line true. It also sets the Status Byte’s request service
(RQS) bit to 1. Both actions are necessary to inform the controller the analyzer requires service.
Setting the SRQ line only informs the controller that some device on the bus requires service.
Setting the RQS bit allows the controller to determine that the Agilent 89400-series analyzer, in
particular, requires service.
If your program enables the controller to detect and respond to service requests, it should instruct
the controller to perform a serial poll when the GPIB’s SRQ line is set true. Each device on the
bus returns the contents of its Status Byte register in response to this poll. The device whose
RQS bit is set to 1 is the device that requested service.
Notes
When you read the analyzer’s Status Byte with a serial poll, the RQS bit is reset to
0. Other bits in the register are not affected.
Restarting a measurement (INIT) can cause the measuring bit to pulse low,
which causes an SRQ if the status register is configured to SRQ on
end-of-measurement. To avoid this:
1. INIT:CONT OFF
2. Set/enable status registers
3. Restart measurement (send INIT)

bits except bit 6. The Service Request Enable register behaves like a standard enable register
except that bit 6 is always set to 0.

16
The Agilent 89400A’s Register Sets
Questionable Modulation Register Set
The Questionable Modulation register set monitors conditions that affect the modulation accuracy
of measurement data. These conditions occur only when option AYA is present. See figure 11.
Figure 11. The Questionable Modulation Register Set
Bits in the Questionable Modulation condition register are set to 1 under the following conditions:
Sync Not Found (bit 0) is set to 1 when the sync pattern cannot be found during a digital
demodulation measurement in which sync search is enabled.
Pulse Not Found (bit 1) is set to 1 when a pulse (an off-on-off transition) cannot be found
within the specified search length during a digital demodulation measurement in which pulse
search is enabled.
Carrier Unlock (bit 3) is set to 1 if you use the VSB demodulation format and the analyzer
cannot obtain carrier lock. VSB demodulation is only available with option AYH (Digital
Video Modulation Analysis). For details about carrier lock with VSB measurements, see the
‘’Video Demodulation Concepts’’ chapter in the Operator’s Guide.
Figure 11 also shows the commands you use to read and write the Questionable Modulation
registers. See the STATUS commands for more information about these commands.
17
The Agilent 89400A’s Register Sets
Standard Event Register Set
The Standard Event register set monitors GPIB errors and synchronization conditions. See
figure 12.
Figure 12. The Standard Event Register Set
The Standard Event register set does not conform to the general status register model described
at the beginning of this chapter. It contains only two registers: the Standard Event event register
and the Standard Event Enable register. The Standard Event event register is similar to other
event registers, but behaves like a register set that has a positive transition register with all bits
set to 1. The Standard Event Enable register is the same as other enable registers.
Bits in the Standard Event event register are set to 1 under the following conditions:
Operation Complete (bit 0) is set to one when the following events occur (in order listed):
– You send the *OPC command to the analyzer.
– The analyzer completes all pending overlapped commands (see “Synchronization” in the
GPIB Programming Guide).
Request Control (bit 1) is set to 1 when both of the following conditions are true:
– The analyzer is configured as an addressable-only device (see “Controller Capabilities”).
– The analyzer is instructed to do something (such as plotting or printing) that requires it to
take control of the bus.
Query Error (bit 2) is set to 1 when the command parser detects a query error.

Figure 12 also shows the commands you use to read and write the Standard Event registers. See
the STATUS commands for more information about these commands.
18
The Agilent 89400A’s Register Sets
Operational Status Register Set
The Operational Status register set monitors conditions in the analyzer’s measurement process,
disk operations, and printing/plotting operations. It also monitors the state of current Agilent
Technologies Instrument BASIC program. See figure 13.
Figure 13. The Operational Status Register Set
Bits in the Operational Status condition register are set to 1 under the following conditions:
Calibrating (bit 0) is set to 1 while the self-calibration routine is running.
Settling (bit 1) is set to 1 while the measurement hardware is settling.
Ranging (bit 2) is set to 1 while an autorange is in progress.
Sweeping (bit 3) has the same state as the Measuring bit when the sweep is Continuous.
When the sweep is Single, the Sweeping bit is 0 until INIT is received and 1 while sweeping.
The negative transition of this bit can be used to determine when INIT:IMM should be sent to
initiate the next sweep. See following table and illustration.
Measuring (bit 4) is set to 1 while the analyzer is actively measuring. The instrument is
considered to be ‘’measuring’’ following an ABOR command or another command which
forces an internal abort such as a configuration change in time data or zoom/baseband
status. So the measuring bit is 1 while waiting for an arm and while waiting for trigger. In
single-sweep it is also 1 while waiting for INT:IMM. It goes low briefly at the end of each
scan.
Waiting for TRIG (bit 5) is set to 1 when the analyzer is ready for a trigger signal from one
of the trigger sources. (If a trigger signal is sent before this bit is set, the signal is ignored.)
Waiting for ARM (bit 6) is set to 1 when both of the following conditions are true:
– External arm is on (ARM:SOURce EXTernal).
– The analyzer is ready to be armed.
Averaging (bit 8) is set to 1 while the analyzer is averaging measurement data. For
exponential and continuous averaging, it stays set to 1 until the specified number of averages
is taken, and then it has the same state as the Measuring bit. See following illustration.
Hardcopy In Progress (bit 9) is set to 1 while the analyzer is printing or plotting.
19
The Agilent 89400A’s Register Sets
Waterfall/Spectrogram (bit 11) is set to 1 when a waterfall or spectrogram is in progress
on any trace measurement. It is set to 0 when all waterfalls and spectrograms are complete
and then it has the same state as the Measuring bit. ‘’Complete’’ means that the specified
buffer depth number of scans have been acquired after the settling is done. ‘’Settling’’ means
that if averaging is exponential, the specified number of averages have been acquired and if
the analyzer is operating real-time, the first time record is full.
Capture in Progress (bit 12) is set to 1 when a time capture begins. It is set to 0 when the
capture either comes to completion or is aborted.
Program Running (bit 14) is set to 1 while the current Agilent Technologies Instrument
BASIC program runs.

User Status Register Set
The User Status register set detects STATus:USER:PULSe commands. See figure 14.
Figure 14. The User Status Register Set
The User Status register set conforms to the general status register model (described at the
beginning of this chapter) with the following exceptions:
You can write (but not read) the condition register.
You cannot write or read the transition registers.
Bits in the positive transition register are always set to 1.
Bits in the negative transition register are always set to 0.
Bit 15 is not available. It is always set to 0.
Bits in the User Status condition register are normally set to 0, but are set to 1 (briefly) when you
send a STAT:USER:PULS command. If you send STAT:USER:PULS 32, bit 5 of the condition
register is pulsed high (25 = 32).

The SCPI Instrument Model
23
Introduction
A model is used within SCPI as a means of achieving compatibility. SCPI concerns itself with
three types of compatibility. The first form of compatibility is called vertical compatibility.
Vertical compatibility is where two instruments of the same type have identical controls.
The second form of compatibility is called horizontal compatibility. Horizontal compatibility is
where two instruments can make the same measurement, regardless of the actual measurement
techniques used. To be horizontally compatibile, both instruments would use the same
commands to make this measurement. For example, both an oscilloscope and a counter can
perform a risetime measurement on a pulse. The two instruments are said to be horizontally
compatible if the same command is used in both instruments.
The third form of compatibility is called functional compatibility. Functional compatibility is where
two instruments which perform the same function do so with the same commands. For example,
a spectrum analyzer and an rf source may both sweep in frequency. If the same frequency and
sweep commands are used in both instruments, they would be functionally compatible in this area.
The figure above represents the way in which instrument functionality is viewed and categorized
by SCPI. The purpose of this categorization is to provide organization and consistancy between
the various commands available in SCPI for all the different types of instrumentation. The model
defines where elements of the language must be assigned in the SCPI hierarchy. Major areas of
signal functionality are shown broken into blocks; each of these blocks are major command
subtrees in SCPI. For simplicity, all connections between blocks are not shown. In this chapter
each subtree is discussed.
ROUTe
The purpose of the signal routing block is to control the routing of signals between an
instrument’s signal ports and its internal signal functionality. Signal routing also controls the
connection from signal port to signal port, where such capability exists. The commands which
control this block are described in the SCPI tree under the ROUTe subsystem.
24
INPut
The purpose of the INPut block is to condition the incoming signal before it is converted into data
by the SENSe block. INPut block functions include filtering, biasing, frequency conversion (such
as a mixer or prescaler function), and attenuation.
SENSe
The purpose of the SENSe block is to convert signal(s) into internal data that can be manipulated
by normal computer techniques. The commands associated with the SENSe block control the
various characteristics of the conversion process. Examples are range, resolution, bandwidth, and
gate time. This block does not include any mathematical manipulation of the data after it has
been converted.
CALCulate
In the measurement function path, the purpose of the CALCulate block is to convert sensed data
into a form more useful to the application. Typical calculations include converting units and
postprocessing calculations.
OUTPut
The purpose of the OUTPut block is to condition the outgoing signal after it has been generated.
The OUTPut block functions include filtering, biasing, frequency conversion (such as a mixer
function), and attenuation.
SOURce
The purpose of the SOURce block is to generate a signal based on specified characteristics and/or
supplied data. The commands associated with this block describe the characteristics of the
generated signal.
TRIGger
The trigger subsystem is used to synchronize device action(s) with events. A device action might
be the acquisition of a measurement or the application of a stimulus. The trigger subsystem
consists of the expanded capability model which is capable of describing very complex device
trigger systems. It also makes provision, through the ARM-TRIGger model, for simple descriptions
of less complicated trigger systems. These two models are consistent and compatible with each
other. The ARM-TRIGger model represents a subset of the capability available in the expanded
capability model.
Special terms in the following discussion are defined as follows. A box in a flow chart diagram
identifies a state of a transition diagram and is referred to as a layer. A sequence is a set of
vertically connected layers. A solid line defines flow of control between states and a dashed line
defines signals used as semaphores.
25
ARM-TRIGger Model
The ARM-TRIGger model represents a level of capability that is often found in a device and is
shown in the following figure. This model has two independent levels of event detection, one in
each of the ARM and TRIGger layers.
Model Layers
The following figures detail each of the various types of layers that may exist in a sequence. Each
layer is shown with a dotted line, used to divide the upward and downward traverses through the
layer. The different traverses are reference in describing the operation of each layer.
IDLE State
On receipt of either *RST or ABORt, the trigger subsystem shall enter the IDLE state. Receiving
the IEEE 488.2 dcas message may also cause a transition to IDLE. Devices which cannot process
commands when not in IDLE must enter IDLE when dcas is received to meet the IEEE 488.2
requirements for device clear. The downward traverse from IDLE state, ‘’trigger system initiated,’’
is affected by either the INITiate[:IMMediate] command or by setting INITiate:CONTinuous to ON.
Exiting the IDLE stat causes the pending operation flag associated with the initiated action to be
set true. Entering the IDLE state causes the pending operation flag to be set false.
26
Initiated
Once the trigger system is initiated from the IDLE state, it passes through the initiated state,
immediately making the downward traverse to the ‘’wait for ARM’’ state. The upward traverse is
dependent on the setting of CONTinuous. If CONTinuous is set to OFF, the upward trasition to
IDLE is made. Otherwise, the downward traverse to the ‘’wait for ARM’’ state is made, and the
trigger sequence remains initiated.
The initiated state avoids having the pending operation flag changes states every time the entire
trigger sequence is completed when CONTinuous is ON.
Event Detection Layer
The ARM and TRIGger layers are both event detection layers with the TRIGger layer being
subservient to the ARM layer. Each layer provides one level of event detection.
The downward traverse through an event detection layer depends on the sourced event being
detected the specified number of times. Typically, the first event detected after entering the
event detection layer is all that is required to proceed. However, a particular number of
27
occurances of the same event may be specified with ECOunt; for example, wait for the tenth
positive edge of a signal. the downward traverse is also subject to a time delay if one is specified.
Two commands override a normal downward traverse. The layer name followed by :IMMediate
causes the event detection and the subsequent delay to be bypassed. The layer name followed by
:SIGNal causes the device to proceed as though a single event had occured.
The upward traverse is dependent on the value of COUNt for the given layer. When COUNt is
greater than one, all of the subservient layers are cycled repeatedly COUNt times, For example,
to make five measurements, each qualified by the same combination of ARM and TRIGger events,
the COUNt in the ARM layer should be set to 5. Each time the ARM layer is entered from below,
the flow is redirected to follow the downward traverse. After the fifth cycle, when COUNt is
satisfied, the upward traverse to the initated state is made.
MEMory
The purpose of the MEMory block is to hold data inside the instrument. The memory may be
implicit and inaccessible to the user (as internal calibration data, for example), may be fixed (as
current measurement data, for example), or may be allocated and user-addressed.
FORMat
The purpose of the FORMat block is to convert between data representations, especially on the
data that is transferred over the external interface. An example is conversion of internal data
formats to ASCII.
Hard COPy
The purpose of the HCOPy block is to control the setup of plotting and printing to an external
device. The Hard COPy subsystem does not perform any data formatting such as converting data
from one representation to another (e.g. COMPlex to POLar). Instead, HCOPy adds the necessary
page formatting (dependent upon the hard copy device language) to turn the data into an
acceptable form for the hard copy device.
DISPlay
The purpose of the DISPlay block is to format data (usually generated by the CALC block) for
presentation on a visual device such as a CRT. The commands associated with this block control
aspects such as scaling, color, layout, and user annotation.
Mass MEMory
The purpose of the MMEM block is to provide access to mass storage devices such as internal
RAM disks or internal or external hard disks or floppy disks. The commands in this block allow

*CLS
command
Clears the Status Byte by emptying the error queue and clearing all event registers.
Command Syntax:
*CLS
Example Statements:
OUTPUT 719;"*Cls"
OUTPUT 719;"*CLS"
Attribute Summary:
Synchronization Required: no
Preset State: not applicable
SCPI Compliance: confirmed
Description:
This command clears the Status Byte register. It does so by emptying the error queue and
clearing (setting to 0) all bits in the event registers of the following register sets:
User Status.
Device State.
Questionable Voltage.
Questionable Frequency.
Limit Fail.
Questionable Status.
Operation Status.
In addition, *CLS cancels any preceding *OPC command or query. This ensures that bit 0 of the
Standard Event register is not set to 1 and that a response is not placed in the analyzer’s output
queue when pending overlapped commands are completed.
*CLS does not change the current state of enable registers or transition filters.
Note
32
To guarantee that the Status Byte’s Message Available and Master Summary
Status bits are cleared, send *CLS immediately following a Program Message
Terminator.
Command Reference
*ESE
command/query
Sets bits in the Standard Event Enable register.
Command Syntax:
<number>
<bound>
*ESE <number>|<bound>
::= a real number (NRf data)
limits: 0:255

OUTPUT 719;"*Ese 30"
Query Syntax:
*ESE?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: dependent on setting of *PSC
SCPI Compliance: confirmed
Description:
This command allows you to set bits in the Standard Event Enable register. Assign a decimal
weight to each bit you want set (to 1) according to the following formula:
2(bit_number)
Acceptable values for bit_number are 0 through 7. Add the weights and then send the sum with
this command.
When an enable register bit is set to 1, the corresponding bit of the Standard Event Event register
is enabled. All enabled bits are logically ORed to create the Standard Event summary, which
reports to bit 5 of the Status Byte. Bit 5 is only set to 1 if both of the following are true:
One or more bits in the Standard Event event register are set to 1.
At least one set bit is enabled by a corresponding bit in the Standard Event Enable register.
The setting last specified with *ESE is saved in nonvolatile memory. It can be recalled at
power-up, depending on the setting of the Power-on Status Clear flag (set with *PSC). When the
flag is 0 at power-up, all bits in the Standard Event Enable register are set according to the saved
*ESE value. When the flag is 1 at power-up, all bits in the Standard Event Enable register are
initialized to 0.
The query returns the current state of the Standard Event Enable register. The state is returned
as a sum of the decimal weights of all set bits.

Example Statements:
OUTPUT 719;"*PCB 19"
OUTPUT 719;"*pcb 19, 1"
Attribute Summary:
Synchronization Required: no
Preset State: not affected by Preset
SCPI Compliance: confirmed
Description:
Use this command to specify the address of your controller before you pass control of the GPIB
to the analyzer. When the analyzer completes the operation that required it to have control of
the bus, it automatically passes control back to the controller at the specified address.
The optional second number is only used for controllers that support extended addressing. It is
interpreted as the secondary address of the controller.
The address last specified with this command is saved in nonvolatile memory, so it is unaffected
when you turn the analyzer off and on. It is also unaffected by the *RST command.
38
Command Reference
*PSC
command/query
Sets the state of the Power-on Status Clear flag.
Command Syntax:
<number>
*PSC <number>
::= a real number (NRf data)
limits: -32767:32767
Example Statements:
OUTPUT 719;"*psc 0"
OUTPUT 719;"*PSC 1"
Query Syntax:
*PSC?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: not affected by Preset
SCPI Compliance: confirmed
Description:
This command lets you specify whether or not the Service Request Enable register and the Event
Status Enable register should be cleared (all bits reset to 0) at power-up.
Sending *PSC 0 sets the power-on-status-clear flag false which allows instruments to assert SRQ
after power-on. Use of any value other than 0 sets the power-on-status-clear flag to true which
Enables the power-on clear status and disallows any SRQ assertion after power-on.
The settings of the Service Request Enable register and the Event Status Enable register are
saved in nonvolatile memory when you turn the analyzer off. These settings can be restored
when you turn the analyzer on, but only if the Power-on Status Clear (PSC) flag is set to 0. When
the PSC flag is set to 1, the two enable registers are cleared at power-up.
The number last specified with *PSC is saved in nonvolatile memory, so it is unaffected when
you turn the analyzer off and back on. It is also unaffected by the *RST command.
If you want to generate a service request at power-up, bit 7 of the Event Status Enable and bit 5
of the Status Byte register must be enabled. This is only possible if the PSC flag is reset to 0
The query returns the current state of the PSC flag (0|1).
39

SCPI Compliance: confirmed
Description:
This command returns the analyzer to a reset state. In addition, *RST cancels any pending *OPC
commands or query.
If a file named AUTO_ST containing an instrument state exists on any drive, that state is loaded
and becomes active at power-on.
The reset state is similar to the preset state. The preset state of each command is listed in the
Attribute Summary for that command. In some cases, a command’s reset state differs from its
preset state (SYST:PRES). These commands (and their reset states) are:
CALibration:AUTO is set to 0 (off).
INIT:CONT is set to OFF.
Note
This command is not equivalent to a front-panel preset (SYST:PRES).
The following are not affected by the *RST command (or SYST:PRES):
The state of the Power-on Status Clear flag.
The state of all enabled and transition registers.
The GPIB input and output queues.
The time and date (SYST:TIME and SYST:DATE).
The GPIB address settings.
– SYST:COMM:GPIB:ADDR
– HCOP:PLOT:ADDR
– HCOP:PRIN:ADDR
The memory configuration.
The GPIB controller capability setting.

Example Statements:
OUTPUT 719;"*sre 0"
OUTPUT 719;"*SRE 5"
Query Syntax:
*SRE?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: dependent on setting of *PSC
SCPI Compliance: confirmed
Description:
Use this command to set the Service Request Enable register to mask, or select, the events which
cause a service request (SRQ). See the section Status Byte Register Set in ‘’Using Status
Registers.’’
Assign a decimal weight to each bit you want set (to 1) according to the following formula:
2(bit_number)
Acceptable values for bit_number are 0 through 7. Add the weights and then send the sum with
this command. Sending *SRE 0 disables SRQ; *SRE 5 enables bits 0 and 2, User Status Summary
and Device State Summary.
Note
The analyzer ignores the setting specified for bit 6 of the Service Request Enable
register. The corresponding bit of the Status Byte register is always enabled.
The analyzer requests service from the active controller when one of the following occurs:
– A bit in the Status Byte register changes from 0 to 1 while the corresponding bit of the
Service Request Enable register is set to 1.
– A bit in the Service Request Enable register changes from 0 to 1 while the corresponding
bit of the Status Byte register is set to 1.
The setting last specified with *SRE is saved in nonvolatile memory. It can be recalled at
power-up, depending on the setting of the Power-on Status Clear flag (set with *PSC). When the
flag is 0 at power-up, all bits in the Service Request Enable register are set according to the saved
*SRE value. When the flag is 1 at power-up, all bits in the Service Request Enable register are
initialized to 0.
The query returns the current state of the Service Request Enable register. The state is returned
as a sum of the decimal weights of all set bits.

decimal weights of all set bits. The decimal weight for each bit is assigned according to the
following formula:
2(bit_number)
Acceptable values for bit_number are 0 through 7.
The register is not cleared by this query. To clear the Status Byte register, you must send the
*CLS command.
Bits in the Status Byte register are defined as follows:
Bit 0 summarizes all enabled bits of the User Status register.
Bit 1 is reserved.
Bit 2 summarizes all enabled bits of the Device State register.
Bit 3 summarizes all enabled bits of the Questionable Status register.
Bit 4 is the Message Available (MAV) bit. It is set whenever there is something in the
analyzer’s output queue.
Bit 5 summarizes all enabled bits of the Standard Event Status register.
Bit 6, when read with this query (*STB?), acts as the Master Summary Status (MSS) bit. It
summarizes all enabled bits of the Status Byte register. (Bit 6 acts as the Request Service
(RQS) bit when it is read by a serial poll.
Bit 7 summarizes all enabled bits of the Operation Status register.

OUTPUT 719;"ARM:SOUR IMMEDIATE"
Query Syntax:
ARM:SOURce?
Return Format:
CHAR
Attribute Summary:
Synchronization Required: no
Preset State: IMM
SCPI Compliance: confirmed
Description:
Immediate triggering corresponds to turning external arm off. In this state the analyzer
operates as usual–it makes a measurement when the trigger conditions are met.
External triggering corresponds to turning external arm on. In this state the analyzer makes a
measurement when these conditions are met, in this order:
1. The analyzer receives a valid ‘’external arm’’ signal.
2. Trigger conditions are met.
The external-arm signal is valid when it meets the conditions set with the ARM’s LEVEL,
REGION, and DELAY commands. The external-arm signal is input via the EXT ARM (BNC)
connector on the analyzer’s rear panel.
When the external-arm signal is valid (as defined by the level and region), it arms the analyzer.
Once armed, the analyzer remains armed regardless of the value of the EXT ARM signal. If the
analyzer receives multiple valid external-arm signals, the first valid signal arms the analyzer; the
others do nothing.

Query Syntax:
CALCulate[1|2|3|4]:FORMat?
Return Format:
CHAR
Attribute Summary:
Synchronization Required: no
Preset State: MLOG
SCPI Compliance: instrument-specific
Description:
The numbers 1 through 4 used with the CALCulate node specify which trace (A, B, C, or D) is to
be affected by the command. If no number is used in the command line, “CALC1" is assumed and
the command affects trace A.
MLIN specifies linear magnitude trace coordinates. When this coordinate type is active, the
trace data is displayed with time or frequency data on the X axis and SQRT(RE2 + IM2) on the Y
axis.
MLOG specifies log-magnitude trace coordinates. When this coordinate type is active and the
display units are dB, the trace data is displayed with time or frequency on the X axis and 10
log(RE2 + IM2)on the Y axis if the data is in power units, or 20 log(RE2 + IM2) if the data is linear
(volts). If the Y-axis units are dBm, the trace data is displayed with time or frequency on the X
2
axis and 10 log(Magrms⁄.001 × Z) on the Y axis where Mag is the input magnitude and Z is the receiver
input impedance (50Ω). The impedance value may be changed with the INP:IMP command.
PHAS specifies wrapped phase trace coordinates. When this coordinate type is active, the Y axis
is phase in degrees. The default scale is ±225°.
UPH specifies unwrapped phase trace coordinates. When this coordinate type is active, the
zero-phase reference and unwrapped-phase offset are values specified by the CALC:UPH:CREF
command (in Hz) and CALC:UPH:OFFS command (in degrees), respectively.
REAL specifies real y-axis trace coordinates versus time or frequency. The real part of time
waveforms is correctly scaled for either baseband or zoom.
IMAG specifies imaginary y-axis coordinates versus time or frequency and displays the
imaginary part of complex data. If the data is purely real, zero values are displayed. Complex
time waveforms have an imaginary part corresponding to the Hilbert transform of the real part
(due to zooming). So, a 2Vpk sine wave input in zoom mode results in a Real Part display of a
(frequency shifted) 2Vpk sine wave, and the Imag Part display will also be a (frequency shifted)
2Vpk sine wave shifted in phase.
57
Command Reference
GDEL specifies group delay trace coordinates. Group delay is the derivative of phase with
respect to frequency, −dϕ⁄df. In this analyzer it is approximated by the function −∆ϕ⁄∆f. The
aperture (∆f) is specified with the CALC:GDAP:APER command.
Note
Digital demodulation features are implemented only if option AYA (vector
modulation analysis) is installed in the analyzer.
The following display formats are part of option AYA.
COMP specifies a complex polar vector diagram, with the real part on the x axis and the
imaginary part on the y axis. When the instrument mode is digital demod, this is an IQ diagram,
with the in-phase signal on the x axis and the quadrature-phase signal on the y axis.
The complex diagram differs from the constellation diagram in that the constellation diagram
shows information only at specified time intervals; the symbol clock times.
CONS specifies a constellation polar vector diagram. This is a time-domain diagram. It displays
information only at symbol clock times (detection decision-points) and the displayed points are
called symbols.
IEYE specifies the in-phase eye diagram.
QEYE specifies the quadrature-phase eye diagram.
TEYE specifies the trellis eye diagram.
For more information on these display types, see online help and the concepts discussion in the
Operator’s Guide.

SCPI Compliance: instrument-specific
Description:
Marker coupling ties the X values of the inactive traces to that of the active trace. This command
couples the markers no matter which trace is specified. No trace number is needed, as in
CALC:MARK:COUP 1.
Marker coupling is applicable only between traces that have the same x-axis coordinates. For
example, marker coupling is meaningless if one trace has x-axis units of Hertz and another trace
has x-axis units of seconds. When coupling is on, changing the position of one marker causes
the marker(s) on other traces of the same type (frequency or time) to move to the same position.

Description:
This command starts a marker measurement whose type is as follows:
BPOW calculates band power. The marker positions are set with CALC:MARK:BAND:START
and STOP.
BRMS calculates rms-square-root of the band power. The marker positions are set with
CALC:MARK:BAND:START and STOP.
BCN calculates the band carrier-to-noise ratio (C/N). The carrier position value used is the
position of the X marker (set with CALC:MARK:X). If the marker is off, this command calculates
noise instead of carrier-to-noise ratio.
BCNO calculates the band carrier-to-noise density ratio. The carrier position value used is the
position of the X marker (set with CALCMARKX). If the marker is off, this command calculates
noise density instead of carrier-to-noise density ratio.
The selected measurement runs and updates itself with every time record gathered (or, for cases
like averaging where multiple time records are needed to create a measurement result, every
time a measurement result is available). To run the same measurement on another set of data,
change the variable of interest, synchronize, and query again.
The query returns the type of measurement that is currently being calculated. To query the data,
use CALC:MARK:FUNC:RES?.

SCPI Compliance: instrument-specific
Description:
This command selects a statistical-power measurement or turns the selected statistical-power
measurement off. You can select peak power, average power, and peak-to-average power (the
ratio of peak-to-average). CALC1 selects trace A for the measurement, CALC2 selects trace B,
and so forth. If no trace is specified, CALC1 is assumed.
To compute the selected power measurement, the trace must contain time-domain data and the
instrument mode cannot be Scalar. You select trace data with the CALCulate:FEED command.
You select the instrument mode with the INSTrument[:SELect] command.
For peak and peak-to-average power, the analyzer uses the value specified by
CALC:MARK:FUNC:STAT:PPCT to compute peak power. For details, see online help for the
[peak percent] softkey and the [statistics on/off] softkey (on the analyzer, press [Help], [Marker
Function], [peak/average statistics], [statistics on/off] or [peak percent]).

Attribute Summary:
Synchronization Required: no
Preset State: 99.99
SCPI Compliance: instrument-specific
Description:
You enable peak-power or peak-to-average power measurements with the
CALC:MARK:FUNC:STAT command. Peak percent is used in peak-power measurements to
specify the probability of peak power. Since peak-to-average power is the ratio of peak power to
average power, peak percent affects peak-to-average power measurements as well as
peak-power measurements.
Peak percent specifies the probability of peak power. For example, a peak percent of 99.8%
means that the instantaneous power will be less-than-or-equal-to the peak power reported by the
analyzer 99.8% of the time. Alternatively, you could say that the instantaneous power will exceed
the peak power reported by the analyzer 0.2% of the time (100% - 99.8%).
CALC 1 sets the peak percent for trace A, CALC2 sets it for trace B, and so forth. If no trace is
specified, CALC1 is assumed. The value is used only when peak power or peak-to-average power
is enabled (by sending CALC[1|2|3|4]:MARK:FUNC:STAT PEAK or
CALC[1|2|3|4]:MARK:FUNC:STAT PKAV).
For additional details, see online help for the [peak power] softkey (on the analyzer, press [Help],

Attribute Summary:
Synchronization Required: no
Preset State: not applicable
SCPI Compliance: instrument-specific
Description:
You use the CALC:MARK:FUNC:STAT command to enable or disable statistical-power
measurements. These measurements compute power using samples from all time records since
the statistical-power measurement began.
The number of samples used is set to zero when you start or restart the statistical-power
measurement. You start the measurement by sending CALC:MARK:FUNC:STAT and enabling a
statistical-power measurement. You restart the measurement by sending the ABOR;*WAI
command or most commands that change measurement parameters (such as range, trigger, or
frequency).
Note that changing the peak percent (CALC:MARK:FUNC:STAT:PPCT) does not restart the
power measurement. Also note that selecting another statistical-power measurement does not
restart the power measurement (for example, switching from peak power to average or
peak-to-average power).
Use CALC:MARK:FUNC:STAT:SMPL? to report the number of samples used in the
statistical-power measurement. CALC1 reports the number of samples used in the
statistical-power measurement on trace A, CALC2 reports it for trace B, and so forth. If no trace
is specified, CALC1 is assumed. If no statistical-power measurement is selected for the specified
trace, the command returns zero.

Description:
This command sets the offset marker’s z-axis position when the selected trace is a waterfall or
spectrogram display.
Each trace in a waterfall or spectrogram display has a time stamp. You specify the z-axis
position of the offset marker by a trace’s time stamp (in seconds).
The time stamp is the traces’s z-axis value in seconds, and is the time that elapsed from when the
measurement began (sending the ABORt command) to when the trace was acquired. The
analyzer automatically selects the closest valid time stamp (the closest valid z-axis position).

Attribute Summary:
Option: AYB (waterfall & spectrogram display)
Synchronization Required: no
Preset State: (see discussion)
SCPI Compliance: instrument-specific
Description:
This command is useful when a waterfall or spectrogram measurement has been made and the
measurement is paused. Before using it, you must turn the trace-analysis feature on; see related
commands listed below.
You can select a trace by its trace number or its time stamp. Trace number 1 represents the
earliest (oldest) data and larger numbers represet more-recent data. If the buffer depth is 100
and 100 traces are displayed, then sending calc:mark:z 100 specifies analysis of the
most-recent measurement trace.
The time stamp is the traces’s z-axis value in seconds, and is the time that elapsed from when the
measurement began (sending the ABORt command) to when the trace was acquired.
The MARKer:Z:UNIT command determines the units returned with CALC:MARK:Z? The number
returned is the absolute number, even if the offset marker is on. If the offset marker is on and
you want to query the marker position relative to the offset marker, send CALC:MARK:Z:REL?.
Limits:
The buffer depth determines the largest trace number or time stamp that you can specify
(DISP:WIND:TRAC:BUFF). If larger numbers are sent, they are interpreted as the largest valid
number and no error messages are generated. The buffer depth is limited by available memory.
Preset Value:
On preset, waterfall and spectrogram displays are turned off. A query issued immediately after a
preset returns the buffer depth value, which is not affected by preset. For a running
waterfall/spectrogram measurement:
If the number of traces displayed hasn’t reached the buffer depth, the value returned with a
101
Command Reference
query is that of the most recent trace.
If the number of traces displayed has reached the buffer depth, the value returned is the
buffer depth.

To set the buffer depth, use DISP:WIND:TRAC:BUFF.
To turn on the spectrogram/waterfall trace-analysis feature, use CALC:MARK:TRAC.

The UNIT subsystem is used to change default parameter units. The specified units apply to both
the command and query. Default units are temporarily overridden by using other (compatible)
units as a suffix to a command parameter, as when ampk is sent while the default is am.
The absolute value of am units represents the instantaneous modulation index where
−1 ≤ am ≤ +1. The units may be linear or logarithmic (dB). Units with /rtHz or 2/Hz
(squared-per-Hz) are PSD data. When am is used without an rms or pk designation, peak units
are assumed, just as is done with volts.
Unit queries must be in the current “family” of units. That is, the CALC:UNIT:AM? query should
be used only when the default Y-axis units are known to be one of the units in the AM units list.

Command Reference
CALibration:AUTO
command/query
Enable or disable the analyzer’s autocalibration function or perform a single calibration.
Command Syntax:
CALibration:AUTO OFF|0|ON|1|ONCE
Example Statements:
OUTPUT 719;":Calibration:Auto OFF"
OUTPUT 719;"CALIBRATION:AUTO OFF"
Query Syntax:
CALibration:AUTO?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: not affected by preset
SCPI Compliance: instrument-specific
Description:
When calibration occurs, all amplitude ranges and all frequencies are calibrated regardless of
instrument setup. The current value is stored in non-volatile RAM and is not affected by preset.
When autocal is enabled, the analyzer automatically calibrates several times during the first two
hours of operation. After that, it automatically calibrates at intervals of 2 hours 20 minutes.
When autocal is disabled, the analyzer calibrates only when CAL:AUTO ONCE is used.
If calibration occurs while an averaged measurement is paused, then CONTinue has the same
effect as ABORt; the averaging process is restarted (average counter set to zero).
The autocalibration state value is stored in non-volatile memory and is not affected by preset.
Note
126
During calibration, a small ac voltage (approximately 2 mV) appears at the
source output connector.
Command Reference
CALibration:ZERO:AUTO
command/query
Controls the auto-zero calibration function.
Command Syntax:
CALibration:ZERO:AUTO OFF|0|ON|1|ONCE
Example Statements:
OUTPUT 719;"cal:zero:auto ON"
OUTPUT 719;"Calibration:Zero:Auto OFF"
Query Syntax:
CALibration:ZERO:AUTO?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: 1
SCPI Compliance: instrument-specific
Description:
Auto zero corrects for residual DC in the input amplifiers. If zeroing is not performed, the DC
value adds to the input signal giving incorrect measurement values and (worst case) may become
large enough to cause ADC overloads or incorrect triggering. Residual DC is the calibration
element most likely to change with time or operating temperature.
The differences between calibration and auto zeroing are:
Auto zeroing takes much less time for the analyzer to perform than a complete calibration
requires.
Auto zeroing has less effect on measurement accuracy than calibration.
The auto-zero feature is a part of calibration that may be activated when automatic calibration is
off. If calibration is on, zeroing cannot be turned off. Turning auto zero off allows you to control
the analyzer without interruptions caused by automatically-initiated operations. If you intend to
run a series of measurements with auto zero turned off, you may want to turn auto zero off and
then perform CAL:ZERO:AUTO ONCE just before beginning.
Note
Selecting ONCE zeros the input and then turns auto zero off. Single auto-zero
calibrations should be performed every 30 minutes or whenever there is a
significant change in the analyzer’s operating temperature.

Description:
The CMAP subsystem controls the physical color associated with each logical color number in
the color map of the display. The numbers 1 through 256 correspond to various display elements
as described in Help Text.
The HSL command sets the instrument’s color map based on the Hue/Saturation/Luminance
levels color model for the user-defined color maps. Before issuing color changes with this
command, select one of the two user-defined color maps with the DISP:WIND:SPEC:MAP
command.
Hue ranges from zero to one, circularly, with a value of zero resulting in the same hue as a value
of one. The approximate color progression is (starting at zero): red, orange, yellow, green, cyan,
blue, magenta, and back to red.
Saturation is the amount of pure color versus white. The saturation value ranges from zero to
one, with zero specifying no color (all white or gray, depending on brightness*) and one
specifying no white.
Luminance specifies the brightness per unit area of the color. A luminance of zero results in
black; a luminance of one results in the brightest color available.

The color map determines the colors that may be used in the spectrogram display. A color map
consists of 64 colors, all of which may or may not be used, as specified by DISP:SPEC:COL
command.
COLOR is a map of 64 colors. This map has a maximum amplitude hue of 0% (red) and a
minimum amplitude hue of 70% (blue). The hue of the other 62 colors are linearly distributed
between 0% and 70%. The saturation and luminosity remain constant for all 64 colors.
RCOLOR is identical to COLOR except that the colors are reversed. The maximum amplitude
hue is 70% and the minimum amplitude hue is 0%.
GREY is a color map of 64 shades of grey. The maximum amplitude has a luminosity of 100%
(lightest shade of grey) and the minimum amplitude has a luminosity of 10% (darkest shade of
grey). The other 62 colors’ luminosity are linearly distributed between 10% and 100%. The hue
and saturation remain constant for all 64 colors.
RGREY is identical to GREY except that the shades of grey are reversed.
MAP1 and MAP2 are used to specify a user-defined color map. These maps may be defined with
the DISP:CMAP:COLOR:HSL command for colors numbered 129 through 192. If you want to
define MAP1, select it with this command, then send the color:hsl commands to define the 64
colors. These definitions are stored in non-volatile RAM.

Query Syntax:
DISPlay[:WINDow[1|2|3|4]]:TRACe:X[:SCALe]:AUTO?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: 1 (ON)
SCPI Compliance: confirmed
Description:
X-axis autoscaling is similar to Y-axis scaling if you understand that the conventional method of
displaying measurement information maps the first measurement data to the left-most X-axis
value and the last measurement data to the right-most X-axis value. This corresponds to X-axis
autoscaling being ON. When it is OFF, other time or frequency values may be mapped to these
X-axis points, as defined by DISP:WIND:TRAC:X:LEFT and RIGHt, respectively.
ON changes the X scale to be the full range of the current data. Sending ON corresponds to
pressing the softkey X full scale (under Ref Lvl/Scale, X scale markers keys). When the trace
displays frequency information, for example, this corresponds to the start and stop frequencies
being mapped to the left-most and right-most values on the X axis. This is the conventional
method of displaying frequency domain data.
OFF corresponds to pressing the softkey hold scale (under Ref Lvl/Scale, X scale markers keys).
This allows the display settings given by the DISP:WIND:TRAC:X:LEFT and RIGHt commands to
be the left-most and right-most values on the X axis. When this is the active display state, the
initial and last display values are not necessarily at the limits of the measurements.
ONCE has no corresponding softkey. It changes the values of the current measurement values
for the left-most and right-most data values to the current values of the LEFT and RIGHT settings
and then turns AUTO OFF.
The Window node is default (use is optional). This specifies which trace (A, B, C, or D) is to be
affected by the command. If the Window node is not used in the command line, “WIND1" is
assumed and the command affects trace A. If WIND is used but no trace number is specified, ”1"
is assumed and the command affects trace A.

Return Format:
Real
Attribute Summary:
Synchronization Required: no
Preset State: 25% of full scale
SCPI Compliance: confirmed
Description:
This command specifies the value of the first (left-most) X-axis point on the display. This,
combined with the RIGHT command, is equivalent to the X-Scale Markers feature in front-panel
operation (under the Ref Lvl/Scale hardkey) which allows you to expand or magnify a narrow
region of data. No new data is taken; existing data is displayed differently.
The Window node is default (use is optional). This specifies which trace (A, B, C, or D) is to be
affected by the command. If the Window node is not used in the command line, “WIND1" is
assumed and the command affects trace A. If WIND is used but no trace number is specified, ”1"

Description:
Sending units with this command does not change the Y-axis units displayed.
To change the Y-axis units displayed, use the CALC:UNIT commands.
To display the reference line (default = off), use DISP[:WIND]:TRAC:Y:RLIN.
If range tracking is on (active), then changing the range setting changes the reference level.
To change the range tracking status, use DISP:WIND:TRAC:Y:RLEV:AUTO.
If range tracking is on and autoranging is on, then the reference level tracks the range and
the range may change automatically, depending on the magnitude of the signal being
measured. To control autoranging, use [SENS:]VOLT:RANG:AUTO.
Changing the reference level doesn’t affect the per-division setting. To specify the vertical
scale per-division, use DISP[:WIND]:TRAC:Y:PDIV.
To autoscale the display, use DISP[:WIND]:TRAC:Y:AUTO.

Command Syntax:
DISPlay[:WINDow[1|2|3|4]]:TRACe:Y[:SCALe]:RLEVel:AUTO OFF|0|ON|1
Example Statements:
OUTPUT 719;":display:trac:y:rlev:auto OFF"

Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: 1 (ON)
SCPI Compliance: confirmed
Description:
The Window node is default (use is optional). This specifies which trace (A, B, C, or D) is to be
affected by the command. If the Window node is not used in the command line, “WIND1" is
assumed and the command affects trace A. If WIND is used but no trace number is specified, ”1"
is assumed and the command affects trace A.
When range tracking is on, the reference level changes when the range setting changes.
Immediately after power is turned on and after a preset, range tracking is “ON” and both values
are 0 dBm (because measurement data is spectrum and data format is log mag). When range
tracking is on, changes in the reference level do not affect the range setting. If the range value is
incremented 4 dB, the reference level is also incremented 4 dB.
Range tracking is invalid for phase, demodulation, and group delay traces and when the
measurement data is frequency response, coherence, or user math. Range tracking is turned
OFF in these cases.
Notes
Range tracking is turned OFF when an autoscale is performed or when the Y
scale is changed for a real, imaginary, or linear magnitude trace.
If range tracking is on and autoranging is on, the reference level may change
when the signal level changes, depending on how autoranging is configured.
Related Commands:
To specify or query range settings, use the [SENS:]VOLT:RANG commands.
To specify or query the reference level, use DISP[:WIND]:TRAC:Y:RLEV.
To specify the position of the reference line, use DISP[:WIND]:TRAC:Y:RPOS.

Description:
The Window node is default (use is optional). This specifies which trace (A, B, C, or D) is to be
affected by the command. If the Window node is not used in the command line, “WIND1" is
assumed and the command affects trace A. If WIND is used but no trace number is specified, ”1"
is assumed and the command affects trace A.
The reference line’s position is set as a percentage of the distance to the top of the trace area:
100% places the line at the top of the trace area, 50% places it at the middle, and 0% places it at
the bottom.
The preset value for time, real, imaginary, or phase data is 50%. When power is first turned on
and after preset, the reference line is off.

Description:
The waterfall display draws a new trace at the top of the screen as older traces move toward the
bottom. The height of a grid is determined by the number of vertically stacked grids. When the
number of grids is single, the vertical height is approximately 300 pixels. When two grids are
displayed, vertical height is approximately 140 pixels.
Limits:
The maximum number of pixels accepted for this command is the number defined under
DISP:FORM SING, which is about 300. This is true, regardless of the active display format
(number of grids). The above discussion is a description of practical limits; setting the elevation
and trace height to values that add to more than what is available just means part of the trace is
not displayed.
To set the number of grids, use DISP:FORM.

SCPI Compliance: confirmed
Description:
SCAL selects Scalar Measurements as the instrument mode. This mode configures the analyzer
to perform scalar measurements (no phase) on either channel. This mode uses stepped FFT
measurement techniques to achieve lower resolution bandwidths. Gated time is NOT available in
Scaler mode.
ADEM and DEM selects the Analog Demodulation Measurements mode. This mode configures
the analyzer to allow AM, PM, and FM demodulation measurements. DEM provides
compatibility with earlier software revisions. Gated time is available in the Analog Demod mode.
DDEM selects Digital Demodulation as the instrument mode. This mode exists only in analyzers
that have option AYA. This mode configures the analyzer to examine signals such as QPSK,
π
DQPSK, 4 DQPSK, BPSK, 8PSK, 16 QAM, 32 QAM, MSK, and FSK modulation formats. It offers
automatic carrier and symbol locking. Gated time is NOT available in Digital Demod mode.
VECT selects Vector Measurements as the instrument mode. This mode configures the analyzer
to perform vector measurements (magnitude and phase) on either channel. This mode does not
use stepped FFT, and thus can not achieve the low resolution bandwidths possible in the Scalar
mode. Gated time is available in the Vector mode.
VDEM selects Video Demodulation Measurements as the instrument mode. This mode exists
only in analyzers that have both options AYA and AYH.
WCDMa selects Wideband CDMA Measurements as the instrument mode. This mode exists only

Attribute Summary:
Synchronization Required: no
Preset State: not applicable
SCPI Compliance: instrument-specific
Description:
This command allocates memory not already allocated to Instrument BASIC or as RAM disk, to
data and math registers. Data registers may be used to save traces, to define math functions, and
as a source of arbitrary source signals. Math registers hold interim results of math calculations.
The size of these registers depends on the largest number of points in a trace that a user may
wish to use. This parameter is called the Maximum Number of Frequency Points. The default
configuration is:
Data Registers: 6
Math Registers: 6
Maximum Number of Frequency Points: 3201
This command does not change the settings for the RAM disk or the amount of memory allocated
for IBASIC programming. If the amount of memory allocated to these two uses is sufficiently
large, the DEFAULT command may not be able to allocate the configuration specified above. If
this occurs, the value of the Maximum Number of Frequency Points is reduced until the
configuration fits into the available memory.
Note
The number of frequency points used is different from the maximum number of
frequency points in that the latter is used to define the amount of memory
allocated to the math and data registers. Each register is configured to accept
the maximum number of frequency points, so making this number larger causes
the register configuration to use more memory.
Related Commands:
To specify the number of frequency points in a trace, use SWE:POIN.
To specify the maximum number of frequency points in a trace, use MEM:MALL:MEAS:FPO.
To specify the Max number of time points, use MEM:MALL:MEAS:TPO.
To specify the number of data registers, use MEM:MALL:MEAS:REG.
To specify the number of math temporary registers, use MEM:MALL:MTEM.
If the IBASIC option (1C2) is installed, program memory is allocated with the
MEM:MALL:PROG command. Option UTH adds 20MB of RAM that may be allocated to
IBASIC programming or a RAM disk volume.
To specify the RAM disk size, use MMEM:INIT.

Description:
Valid values for this parameter are 51, 101, 201, 401, 801, 1601, or 3201. The current value is
stored in non-volatile RAM and is not affected by preset. The factory default is 1601.
The value specified with this command must be equal to or greater than:
The number of frequency points for the trace.
The number of points in any stored trace that you wish to recall.
Note
The number of frequency points used is different from the maximum number of
frequency points in that the latter is used to define the amount of memory
allocated to the math and data registers as well as setting a limit on the number
of frequency points currently selected. Each register is configured to accept the
maximum number of frequency points, so making this number larger causes the
register configuration to use more memory.
The standard amount of RAM is supplemented with a 20 MB RAM board (option UTH), which
includes additional I/O (another GPIB connector and a LAN interface).

SCPI Compliance: instrument-specific
Description:
W-CDMA measurements require large amounts of memory. The analyzer allocates enough
memory to accomodate the frequency span set by this command. Reducing the amount of
memory allocated for W-CDMA measurments frees memory for other purposes.
For best performance, set the maximum W-CDMA span to the smallest frequency span that you
will measure.
The maximum W-CDMA span may limit the maximum chip rate. If you cannot set the chip rate
to its maximum value, increase the maximum W-CDMA span.

usage. All digital demodulation types except FSK have a fixed MSSR ratio of 15.625. Only the
MSSR for FSK can be user-defined. Increasing the ratio value increases the amount of memory
allocated for the measurement.
This memory configuration command is valid only for the FSK modulation type. The current
value is stored in non-volatile RAM and is not affected by preset. The factory default is 30.
The standard amount of RAM is supplemented with a 20 MB RAM board (listed in the options as

Description:
To copy a file, include a filename with the source device. To copy a file and change the name,
include filenames with both source and destination devices. <device> values are defined under
MMEM:MSIS. If the destination filename is not specified, the source and destination must be
different devices. Files may also be moved with the LAN file-transfer utility, FTP (option UG7).
To copy an entire disk, use the mass storage unit specifier (device) for the <source> and
<destination> with no filenames. The device selector and unit number specifiers are valid only
with the EXT: specifier. See MMEM:NAME for filename conventions and wildcard usage.
Caution
All files on the destination are overwritten by a disk copy operation.
Related Commands:
To rename a file, use the MMEM:MOVE command.
To specify the default device, use MMEM:MSIS (mass storage is).
To display directory listings, use SCR:CONT MMEM.
Notes
When the control program instructs the analyzer to access the external mass
storage device (EXT:), the controller must temporarily pass control (of the bus)
to the analyzer. After the command has been executed, the analyzer passes
control back. See GPIB Programmer’s Guide for more on passing control.

Preset State: not applicable
SCPI Compliance: confirmed
Description:
<device> is the mass storage unit specifier; usually a disk drive, but also used to indicate RAM
or NVRAM volumes (which perform as very fast drives) or any external mass storage device
(EXT:).
<device_selector> and <unit_number> specifiers are valid only with the EXT: device specifier.
A device_selector is composed of the select_code (usually 7) and the GPIB address (0-30). The
unit-number specifies the drive within a drive unit as would be the case for a dual floppy drive.
LIF|DOS specifies the disk file system type. The default selection is DOS. LIF (logical
interchange format) is used by most HP hard disks. DOS (disk operating system) is used on IBM
personal computers. The RAM disk is formatted every time power is turned on, using a volume
size stored in NVRAM and the same file system type as NVRAM.
Note
If you plan to move data in NVRAM or RAM to an external system, it is best to
initialize NVRAM and RAM disks with the same file system type (LIF or DOS) as
the destination system uses to avoid having to convert filenames and data
formats.
<format> specifies the tracks/sector-format for a flexible disk, either internal (INT:) or external
(EXT:). The default value is 0. See table. For a hard drive, <format> should be 0.
For flexible disk drives, the value determines the disk’s capacity as shown in the following
table. For DOS disks, <format> should be 16. If DOS is specified and <format> is not, 16 is
used.
For device = NVRAM, <format> is ignored. See first example.
For device = RAM, <format> specifies the amount of memory to allocate (for a RAM volume)
225
Command Reference
in bytes. See second example. The amount of RAM available is dependent on the amount of
RAM installed, whether IBASIC and programs are loaded, the number of channels in use, the
maximum number of frequency points, and the number of data registers. For information on
memory configuration, see “Memory” in the Help Text.
<i> is the disk interleave value. It is ignored for RAM and NVRAM. Default is 1 for LIF; 3 for DOS.
Note
When the control program instructs the analyzer to access the external mass
storage device (EXT:), the controller must temporarily pass control (of the bus)
to the analyzer. After the command has been executed, the analyzer passes
control back. See GPIB Programmer’s Guide for more on passing control.

Query Syntax:
MMEMory:LOAD:CONTinue?
Return Format:

Attribute Summary:
Synchronization Required: no
Preset State: not applicable
SCPI Compliance: instrument-specific
Description:
Time capture files that are too large to fit on the current disk may be split and stored on more
than one disk with the MMEM:STOR:CONT command. The MMEM:LOAD:CONT command is
used to load these split files back into the analyzer.
When the analyzer has completed loading the first part of the split file (for example, filename_1),
it generates the message, ‘’Media full; Insert next disk with ‘filename_2’.’’ Insert the disk
containing the file named filename_2 and send MMEM:LOAD:CONT to continue loading the file.
Use MMEM:LOAD:CONT? to verify that the file has been transferred. If the query returns a +1,
the transfer is not complete. The query returns a 0 when the transfer is complete.
When a trace buffer or time capture file is merged, you are prompted to change media at the end
of each file. Pressing the Local/Setup key (or any key) on the front panel in Local mode causes
the file merging operation to terminate. SCPI commands, however, sent between operations do
not terminate the file operation.
Large files may also be transferred between the analyzer and a controller with the LAN
file-transfer utility, FTP (option UG7).
For more information on the generation of split files, see the MMEM:STOR:CONT command.

<destination>. See MMEM:NAME for filename conventions and wildcard usage.
The <device> values are defined under MMEM:MSIS.
Related Commands:
Use MMEM:MSIS (mass storage is) to specify the default device.
Use MMEM:COPY to copy files from one device and/or path to another without deleting the
source.
Use SCR:CONT MMEM to display directory listings.
Note
When the control program instructs the analyzer to access the external mass
storage device (EXT:), the controller must temporarily pass control (of the bus)
to the analyzer. After the command has been executed, the analyzer must pass
control back. See GPIB Programmer’s Guide for more on passing control.
235
Command Reference
MMEMory:MSIS
command/query
Specifies a default mass storage device (disk) and (for DOS) directory.
Command Syntax:
MMEMory:MSIS ‘<device>’
<device>
::= NVRAM:|RAM:|INT:|EXT[,<device_selector>[,<unit_number>]]:

Query Syntax:
MMEMory:MSIS?
Return Format:
STRING
Attribute Summary:
Synchronization Required: no
Preset State: saved in non-volatile memory
SCPI Compliance: confirmed
Description:
<device> is the mass storage unit specifier; usually a disk drive, but also used to indicate RAM
or NVRAM volumes (which perform as very fast drives) or any external mass storage device
(EXT:). For DOS file systems, a directory may also be specified (see third example). The device
types are:
NVRAM: selects the non-volatile RAM drive.
RAM: selects the volatile RAM drive.
INT: selects the internal drive.
EXT: selects the external drive.
<device_selector> and <unit_number> specifiers are valid only with the EXT: device
specifier. A device_selector is composed of the select_code (usually 7) and the GPIB address
(0-30). The unit-number specifies the subunit within a volume as for a dual floppy drive. If
device_selector and unit_number are specified with this command, they become the default for
the external (EXT:) specifier.
Related Commands:
To determine the type of file system for the default disk, send the MMEM:FSYStem? query.
To display the directory contents, use SCR:CONT MMEM.
Note
236
When the control program instructs the analyzer to access the external mass
storage device (EXT:), the controller must temporarily pass control (of the bus)
to the analyzer. After the command has been executed, the analyzer must pass
control back. See GPIB Programmer’s Guide for more on passing control.
Command Reference
MMEMory:NAME
command/query
Specifies the filename for printing or plotting to a file.
Command Syntax:

MMEMory:NAME ‘[<device>]<filename>’
::= RAM:|NVRAM:|INT:|EXT[,<select_code>[,<unit_number>]]:
<select_code>
::= a real number (NRf data)
limits: 700:730
<unit_number>
::= a real number (NRf data)

Example Statements:
OUTPUT 719;":Mmemory:Name ‘plot1.hpg’"
OUTPUT 719;"MMEM:NAME ‘INT:3RD-IF_PCL’"
Query Syntax:
MMEMory:NAME?
Return Format:
STRING
Attribute Summary:
Synchronization Required: no
Preset State: “plotfile”
SCPI Compliance: confirmed
Description:
This command is used to specify a filename when printing or plotting to a file. Specifying FILE
as the output destination is done with the HCOP:DEST FILE command.
If no mass storage unit specifier (msus) is given, the device specified with the last MSIS (mass
storage is) command is used. If MSIS has not been used since the last preset, then msus =
NVRAM (non-volatile RAM).
If EXT is specified, control of the bus must be passed to the analyzer.
Filename and Wildcard Conventions:
DOS filenames are limited in length to 8 ASCII characters followed by a period and an
(optional) extension of one to three characters. Both the period and extension are optional. The
period is not part of the filename; it separates the name and extension. DOS filenames are not
case sensitive. Valid special characters are _, ^, $, ~, !, #, %, &, -, {, }, (, ), @, ‘, ‘. A name may not
contain spaces, commas, backslashes, or periods (except the period that separates the name and
extension). Reserved names that may not be used are CLOCK$, CON, AUX, COMn (n = 1–4),
LPTn (n = 1–3), NUL, and PRN.
LIF filenames are limited in length to 10 characters which may include any character except :, <,
and |. The first character must be a letter. LIF filenames are case sensitive.
Wildcards allow you to identify more than one file when a filename is used as a command’s
argument, such as for copy or delete. A wildcard character can match part or all of the filename.
Two characters are used as wildcards: ? matches any single character and * matches all
characters to the end of the name. To match all filenames starting with B, use B*. You can use
the asterisk to identify files that have common first characters, but not files with matching
237
Command Reference
character patterns in the middle or end of the name. Characters that appear after the * are
ignored because the asterisk is expanded to all possible combinations of the question-mark
wildcard(s) to the end of the name. For example, *ANT matches all filenames, just as * would
(see following table). Question-mark wildcards may be used if the filename pattern to be
matched has a fixed number of characters that vary.
Wildcards work differently for DOS than for LIF because DOS has two fields to use wildcards in;
the filename and the extension. To match all files in a DOS system, use *.*; in LIF just * does it.
In DOS, a single * matches all filenames that have no extension. To match all files (in DOS) with
a particular extension, use * (for the filename) and the extension, as in *.DAT. Remember that,
in LIF, the period character (.) is just another ASCII character, may be used more than once in a
file, and may be matched by a wildcard. In DOS, a period cannot be matched by a wildcard
because it isn’t part of the filename.

MMEMory:STORe:CONTinue
command/query
Allows a large time capture file to be split over multiple disks.
Command Syntax:
MMEMory:STORe:CONTinue
Example Statements:
OUTPUT 719;":mmemory:stor:continue"
OUTPUT 719;"Mmem:Stor:Continue"
Query Syntax:
MMEMory:STORe:CONTinue?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: not applicable
SCPI Compliance: instrument-specific
Description:
If the amount of time capture data to be stored is more than the available space on the
destination disk, the error message, ‘’Media full; File too large’’ is generated. This error message
is generated before the store operation begins. Send the MMEM:STOR:CONT message to begin
the store operation.
MMEM:STOR:CONT adds a numeric specifier to the filename. Split files appear as filename_1,
filename_2, etc. in the disk catalog (see DISP:CONT MMEM).
MMEM:STOR:CONT? returns a +1 when queried before the transfer is complete. Insert another
disk and send MMEM:STOR:CONT to continue the store operation. The query returns a 0 when
the entire file has been stored.
When a trace buffer or time capture file is split, you are prompted to change media at the end of
each file. Pressing the Local/Setup key (or any key) on the front panel in Local mode causes the
file splitting operation to terminate. SCPI commands, however, sent between operations do not
terminate the file operation.
Large files may also be transferred between the analyzer and a controller with the LAN
file-transfer utility, FTP (option UG7).

Option: 1C2 Agilent Technologies Instrument BASIC
Synchronization Required: no
Preset State: not applicable
SCPI Compliance: confirmed
Description:
This command transfers a program between the analyzer and the controller. This allows
programs developed on a controller to be loaded into the analyzer. The first parameter specifies
the analyzer’s program buffer (the destination), which becomes the active program buffer. The
second parameter is the Instrument BASIC program.
A program may be transferred to the analyzer with either the definite-length or the
indefinite-length block syntax. The simplest way to load an Instrument BASIC program is to
send this command followed by #0, followed by all the characters making up the program
(including line numbers and line feeds at the end of each program statement). Terminate the
entire command with line feed character (ASCII decimal 10) and <^END> (the GPIB END
message, EOI set true). See example above.
When the analyzer returns the program to your controller, it always uses the definite-length
block syntax. See ‘’Block Data’’ in the GPIB Programmer’s Guide for more information.

Attribute Summary:
Option: (see COMBine discussion)
Synchronization Required: no
Preset State: 89410: INP, 89441: RF2
SCPI Compliance: instrument-specific
Description:
INPut specifies the configuration in which the signal to be measured is connected to the
front-panel connector labeled Channel 1. This is the default selection for the 89410A. It is valid
only for the 89410A.
RF2 specifies the configuration in which the signal to be measured is connected to the input
connector of the RF Section and the spectrum of interest is between 2 MHz and 2.650 GHz for the
89441A. This is the default selection for the 89441A. It is valid only for the 89441A.
RF1 specifies the configuration in which the signal to be measured is connected to the input
connector of the RF Section and the spectrum of interest is between 0 Hz and 10 MHz. This is
similar to the IF configuration but offers the advantage of not changing the input cable
connections. For best 75Ω impedance matching and calibration of measurement results, use IF.
This selection is valid only for the 89441A.
IF specifies the configuration in which the signal to be measured is connected to the Channel 1
connector of the IF Section and the spectrum of interest is between 0 Hz and 10 MHz. This is
similar to the RF1 configuration but offers the advantage of better matching for 75Ω impedances
(as opposed to using a minimum loss pad on the RF Section) and better calibration of
measurement results. It’s disadvantage is that it requires reconfiguring the input cabling if you
were previously making measurements above 10 MHz. This selection is valid only for the 89441A.
COMBine specifies the configuration in which data from both input channels are combined as I
+ jQ (Ch1 + j*Ch2). This feature is part of option AYA (vector analysis/digital demod) and
requires the presence of option AY7 (the second 10 MHz input channel). For more information
on I + jQ, see online help (press the [ Help ] key, press 1 to show the index, use the knob or
arrow keys to move through the list to input section (Ch1+jCh2), then press 4 to jump to the
discussion).
EXTernal specifies the configuration in which the input comes from an external downconverter
such as the Agilent 89411A. This configuration has more commands under [SENS:]FREQ:EXT.

Averaging overview:
Averaging is turned on with the AVER ON command.
AVER:IRES turns fast averaging on and off.
AVER:IRES:RATE specifies the fast averaging update rate.
AVER:TYPE specifies the average type: RMS (power), complex (time), or max (peak hold).
AVER:TCON specifies termination control types which are normal, exponential, or repeat.
– For normal averaging (AVER:TCON NORM), AVER:COUN specifies the number of
measurement results that are averaged together. When the specified number of
measurements have been taken and averaged together, the analyzer quits taking data and
sets the NPO flag (No Pending Operations) to 1.
– If repeat averaging is on (AVER:TCON REP), the averaging process restarts immediately
after the current average is completed.
– For exponential averaging (AVER:TCON EXP), AVER:COUN specifies a weighting factor
which determines how the results of previous (averaged) measurement data (AVGi−1) is
combined with the current measurement data (Xi). The data is combined point-by-point
as described by:
AVGi =
1
n−1
Xi +
AVGi−1
n
n
where n is the weighting factor specified by AVER:COUN. Note that for small values of
n, the new data is a significant part of the average; for large values of n, new data has
much less weight in the calculated average.
Note
262
For exponential averaging, the averaging process does not stop after n
measurements. The NPO flag is set to 1 after n measurements.

Query Syntax:
[SENSe:]AVERage[:STATe]?
Return Format:
Integer
Attribute Summary:
Synchronization Required: no
Preset State: +0
SCPI Compliance: confirmed
Description:
When averaging is off, each trace represents the results of a single measurement. When
averaging is on, each trace represents the combined results of several measurements.
AVER:TYPE specifies how results are combined.
AVER:TCON (terminal control) specifies how the averaging process terminates.
AVER:COUN specifies the number of measurements to be averaged together (for normal
averaging) or a weighting factor (for exponential averaging).
AVER:IRES turns fast averaging on and off.
AVER:IRES:RATE specifies the fast averaging update rate.
To determine when averaged measurement data is available, use *OPC (operation complete) as
described in chapter 3 of the GPIB Programmer’s Guide under “Synchronization.”
When averaging is off, the NPO flag (No Pending Operation) is set when the current
measurement scan is complete.
When averaging is on, the NPO flag is set when the number of averages requested has been
completed. Even when the type is exponential and the number of averages is used as a
weighting factor (the averaging process never stops), the NPO flag does eventually get set.
If the measurement is restarted with the *ABOR command, the NPO flag is not set until the
requested number of averages is taken.
Note
266
Trigger conditions must be met for each measurement; even when averaging is
on.

Query Syntax:
[SENSe:]AVERage:TYPE?
Return Format:
CHAR
Attribute Summary:
Synchronization Required: no
Preset State: RMS
SCPI Compliance: confirmed
Description:
Averaging is turned on with AVER ON. AVER:TYPE may be specified before averaging is turned
on, however. The three averaging types are RMS (power), COMPlex (time), and MAX (peak hold,
a display function).
RMS (root mean squared) is a power average which reduces the variance of each point’s
magnitude and smooths the noise floor. This averaging type does not lower the noise floor as
complex averaging can.
COMPlex or time averaging is available only when the instrument mode is vector (INST VECT).
Complex averaging reduces the variance of each point’s real and imaginary parts which lower’s
and smoothes the noise floor.
MAX is the same as peak hold, which displays the maximum value of each displayed point over
the course of several measurements (the measurement count is specified with AVER:COUN).
When you press softkeys in the front-panel menus to select average type, you also select the type
of termination control used to calculate average information. The following table shows the
command strings that correpsond to the average type softkeys. To display the SCPI command
strings that correspond to front-panel keys, activate the SCPI command echo by pressing [
Local/Setup ], [ SCPI cmd echo on ] or sending “SYST:GPIB:ECHO 1”. Subsequent SCPI command

GPIB Programmer’s User Guide. The TCAP1 parameter designates the channel-1, time-capture
buffer and TCAP2 designates the channel-2, time-capture buffer.
The analyzer can’t load indefinite-length blocks; the data must be definite-length blocks or ASCII
data. The data is stored internally in 32-bit integers but the data transferred with this command
is floating-point. The floating-point numbers are scaled and converted to integers with the
time-capture range value specified with the [SENSE:]TCAP[1|2]:RANG values. Using the
time-capture range to scale the data yields the best dynamic range.
The query form of this command requires the use of a parameter: TCAP1|TCAP2 as in
DATA? TCAP1
Related Commands:

send “DDEMod:TIME:CCHannel 3" to select code channel 3; send ”DDEM:TIME:CLAY 16000" to
select code layer 16000 sym/s.
NOTE
Option 080 use code layer 16000 sym/s.
Options B73 and B79 use code layer 15000 sym/s.
The available code layers are determined by the demod format (set with the SENSe:DDEM:SEL
command) and the chip rate (set with the SENSe:DDEM:CRATe command).

Synchronization Required: no
Preset State: not applicable
SCPI Compliance: instrument-specific
Description
When the instrument mode is Wideband CDMA, this command turns time gating on or off. When
time gating is on, the analyzer uses the values of DDEMod:TIME:GATE[:SPAN] and
DDEMod:TIME:GATE:DELay for the gate length and gate delay.
Gate length sets the width of the gate (in whole slots); gate delay determines the delay, or offset,
of the gate (in whole slots). For example, a gate length of 3 and gate delay of 1 displays results
for three slots, starting at slot two— in other words, slots 2-4.
For further details about time gating, select the Wideband CDMA instrument mode on the
analzyer and see online help for the [gate on/off] softkey (under the [Time] hardkey).

Return Format:
Integer
Attribute Summary:
Option: AYA (vector modulation analysis)
Synchronization Required: no
Preset State: +1 (ON)
SCPI Compliance: instrument-specific
Description:
This feature determines how the analyzer locks to the carrier frequency. Has no effect on AM
demodulation.
ON uses an algorithm to lock to the carrier frequency. The center frequency of the analyzer
should be set to or near the frequency of the carrier (the modulation format must not be
suppressed-carrier).
OFF assumes the carrier to be at the analyzer’s center frequency. The accuracy of the setting
affects phase accuracy in PM demodulation and dc offsets in FM demodulation. This method is
useful when the carrier is too small to detect, when the carrier frequency is hopping within the
span, or when the analyzer is locked to an external reference which is locked to the carrier. The
accuracy required for setting the center frequency on the carrier varies with the span setting, but
keeping it within 0.5% of the carrier frequency is recommended for PM.
325

OUTPUT 719;"detector SIGNAL"
Query Syntax:
[SENSe:]DETector[:FUNCtion]?
Return Format:
CHAR
Attribute Summary:
Synchronization Required: no
Preset State: POS
SCPI Compliance: confirmed
Description:
The detector function operates only in scaler instrument mode and only when there are more
data points than display points. Then it is used to select which data points are displayed.
SIGNal peak detection tests whether the signal rises and falls within the cell represented by a
given data point. When the signal both rises and falls, the odd-numbered data point indicates the
maximum value and the even-numbered data point indicates the minimum value encountered
during its cell. This algorithm does a good job of combining noise and discrete spectral
components, but does not give a true randomness of noise.
SAMPle detection digitizes the instantaneous value of the signal at the end of each cell. It is the
best way to indicate the randomness of noise.
POSitive detection insures that all sinusoids maximum value encountered in each cell is
displayed. This mode does not give a good representation of random noise either, because it
captures the crests of the noise.

SCPI Compliance: instrument-specific
Description:
When signal tracking is enabled, the analyzer adjusts the value of the center frequency to keep
the largest signal centered in the current frequency span. Selecting either INP1 or INP2 turns on
signal tracking.
INP1 turns on signal tracking and uses channel 1 input signal to determine center frequency.
INP2 turns on signal tracking and uses the signal on channel 2 to determine center frequency.
INP2 should not be selected unless the (optional) second channel is installed.

Query Syntax:

Return Format:
Real
Attribute Summary:
Synchronization Required: no
Preset State: 0 S
SCPI Compliance: instrument-specific
Description:
The sweep node numbers (1|2) specify which input (receiver) channel is affected by the
command. If no number is specified, the command is applied to channel 1. Note that channel 2
is optional (AY7) and may not be installed in the analyzer. To determine whether the second
channel is installed, send *OPT? and see if AY7 (second channel) is returned.
Limits:
Pretrigger ‘’delay’’ is the amount of time before the trigger occurs that you want data; the trigger
occurs after the point in time that you want to begin collecting data. This is specified by entering
a negative number and is limited by the size of the time capture RAM available for the
measurement.
Without the time capture RAM (option AY9), there are 64K samples (65,536) available. When a
second channel is installed and enabled, the pretrigger delay limit is half what it is when only one
channel is enabled; 32K per channel. With deep capture RAM, option AY9, there are 1M samples
(1,048,576) available; .5M per channel if the optional second channel is enabled. The amount of
time represented by these sample sizes depends on the time each sample represents, which
varies with span (∆t).
Post-trigger delay is the amount of time after the trigger occurs that you want to begin the time
record. This is limited by the range of a counter that can count to 2G (2,147,483,648) samples.
This parameter is not affected by the presence of the capture RAM or second-channel options.
Again, the time represented by this count depends on the time each sample represents, which
varies with span (∆t).
In scalar mode, the analyzer picks the span used for the measurement. This affects the resolution
in that ∆t becomes a function of measurement parameters other than the user-specified span.

Return Format:
Real
Attribute Summary:
Synchronization Required: no
Preset State: 0 S
SCPI Compliance: instrument-specific
Description:
The sweep node numbers (1|2) specify which input (receiver) channel is affected by the
command. If no number is specified, the command is applied to channel 1. Note that channel 2
is optional (AY7) and may not be installed in the analyzer. To determine whether the second
channel is installed, send *OPT? and see if AY7 (second channel) is returned.
Note
Time operations do not function when the instrument mode is scalar. When the
measurement is zoomed, a local oscillator signal is mixed with the measurement
data and time data is not baseband. Time gating is not available in digital demod.
Limits: The time gate is defined by the gate delay, which defines its starting time relative the the
beginning of the main time record, and gate length, which defines when it stops relative to its
start. Both start and stop values must be within the main time record, also called main time. So
the lower limit of the gate delay is zero and the upper limit depends on the gate length defined
with SWE:TIME:GATE[:SPAN] as follows:
maximum gate delay = main length − gate length
The minimum gate delay is 0.
Related Commands:
To set the gate delay step size, use SWE:TIME:GATE:DEL:STEP.
To turn the gate on, use SWE:TIME:GATE:STATE.
To set the gate time, use SWE:TIME.

SCPI Compliance: instrument-specific
Description:
The numbers in the sweep node which normally specify an input channel for the command to
affect, has no channel-specific affect for this command; if AUTO is ON, it affects all installed
input channels.
Note
Time operations do not function when the instrument mode is scalar. When the
measurement is zoomed, a local oscillator signal is mixed with the measurement
data and time data is not baseband. Time gating is not available in digital demod.
Span determines time sample spacing and the number of frequency points determines the
maximum record size (meaning points, not seconds). As the main time record length increases,
more and more time samples are required. When the number of samples exceeds the maximum
time record size, either the sample rate may remain the same and the main length be limited or
the sample rate may be reduced, allowing main length to grow.
If AUTO is OFF, the sample rate (and thus span) is not changed to accommodate long main time
lengths.
If AUTO is ON, the sample rate (and thus span) is adjusted to acquire the most time points
possible without exceeding the maximum time points allowed by the number of frequency points
set with SWEep:POINts.

SCPI Compliance: instrument-specific
Description:
The numbers in the sweep node which normally specify an input channel for the command to

input channels.
Note
Time operations do not function when the instrument mode is scalar. When the
measurement is zoomed, a local oscillator signal is mixed with the measurement
data and time data is not baseband. Time gating is not available in digital demod.
Limits: The size of the time record is a function of the number of points in the time record and
the amount of time each point represents (inverse of the effective sample rate). The effective
sample rate is a function of span. The limits, in terms of time, vary with the span, window type,
and number of frequency points. Usually, you will pick a span and then pick either record length
or RBW. Changing either parameter changes the other. So the limits depend on the current
span. The maximum time record length occurs at maximum frequency points (3201), minimum
span (1 Hz), and minimum resolution bandwidth (700 µHz; minimum RBW occurs in arbitrary
RBW mode). The time record length at these settings is 3.2 ks. The minimum time record
length occurs at the maximum span (10 MHz) and maximum RBW (3 MHz). The time record
length at these settings is 351.5625 ns for the uniform window, and 1.2890625 µs for flattop
window. The number of frequency points is not a consideration for the minimum time record
length because of a limit on the maximum RBW/span ratio.
If SWE:TIME:AUTO is ON, increasing the time record length decreases the span automatically
when span becomes the limiting factor. The preset value is OFF.

Attribute Summary:
Synchronization Required: no
Preset State: +3.2768E+4 (POINTS)
SCPI Compliance: instrument-specific
Description:
Option AY9 adds 1 Megasample RAM for time capture.
Limits: The limits are defined by a number of things. The first limit is set by the amount of
installed time capture memory. Without the optional time capture RAM, the capacity is 32
KSamples in two channels. (If the analyzer has only one channel or channel 2 is off, the capacity
is 64 KSamples.) With the optional time capture RAM, the capacity is 512 KSamples in two
channels. (If the analyzer has only one channel or channel 2 is off, the capacity is 1024 KSamples
or 1 MSample.)
Each sample takes 8 bytes, 4 real and 4 imaginary. If the data is moved out of the analyzer,
baseband data is real-only (4 bytes) and zoomed data is real/imaginary (4/4 bytes). If data is
captured and transferred out of the analyzer, be aware that the capture was done in /2 spans.
When the captured data is analyzed in the analyzer, this limitation is eliminated by resampling to
get arbitrary (other-than- /2) spans.
To determine how much time is available (limits in terms of seconds) you must also consider the
span and resolution bandwidth settings. The relationship between these values is as follows:
L = N × ∆t, where L is record length, N is the number of samples, and the time between samples
k × 2.56 × span
1
. We also know that N =
where k is window bandwidth,
is ∆t =
RBW
(span × 2.56)
and RBW is resolution bandwidth.
k
as long as N is not larger than the installed memory
RBW
(standard = 32 KSamples, option = 1 MSample). See concepts for values of k.
Substituting for N and ∆t we get L =

To set the autorange direction, use SENS:VOLT:RANG:AUTO:DIR.
To execute one autorange, send SENS:VOLT:RANG:AUTO ONCE. The analyzer then samples
the input signal value and selects a fixed range setting (autoranging is turned off).
The voltage node numbers (1|2) specify which input (receiver) channel is affected by the

Preset State: EITH
SCPI Compliance: confirmed
Description:
By default, autoranging is off.
UP sets the direction of autoranging value changes to be larger (up) but not smaller (down).
This mode is better than EITHer for setting the range to measure transient signals because it
avoids the measurement interruptions caused by frequent autoranging but may not have the
optimum range setting for best signal-to-noise ratio.
EITH sets the direction of autoranging value changes to be either up or down. This mode tracks
the signal amplitude, if it changes slowly, and optimizes the range for best signal-to-noise ratio.
If the signal of interest is transient, the EITHer setting may spend too much time selecting a new
range instead of making measurements.
Note
When the analyzer is configured such that it measures signals from a
downconverter (like the RF section or the Agilent 89411A; when

Description:
After preset and when power is first turned on, the source is off.
The OUTP 1 command may be used to turn it on.
The amplitude value is specified with the SOUR:VOLT command.
Arguments used with the SOUR:FUNC command are as follows:
SIN selects fixed sine as the source output type. The signal is a continuous sine wave output at
the center frequency of the current measurement or sub-measurement. The frequency of this
signal is specified with the SOUR:FREQ command.
RAND selects random noise (with a Gaussian distribution) as the source output type. This
source type’s peak-to-rms ratio is not as low as the chirp signal, but the energy at any of the tones
is not concentrated at a particular point in time, making it useful for measuring some dispersive
networks.
Random noise yields a fast, linear estimate of the system under test. Because it is not
periodic in the time record, random noise requires windowing; usually the Hanning window.
The bandwidth of the random noise is set so that most of the energy in the source signal is
within the measured span.
PCH selects periodic chirp as the source output type. The signal has a low peak-to-rms ratio,
useful for network measurements.
USER selects a user-defined source signal stored in one of the six data registers, D1–D6. The
particular data register is selected with the SOUR:FUNC:USER:FEED command. The data must
be in SDF format. Data for arbitrary source signals may have been time-domain traces that were
saved earlier, created with commercial software such as PC Matlab, or defined with a BASIC
program.

This function (repeating source) is available only when the source type is periodic chirp or
arbitrary, the trigger type is not free run, and the source is on. See help text for information.
When repeat is on, the analyzer outputs data to the source connector continuously, without
interruption.
When repeat is off, the source behavior is affected by trigger mode. In free run trigger, source
output is continuous, just as it is with repeat on. For any other trigger mode, the source begins
its output only when a trigger occurs and shuts off after all the data in the register has been
output. This happens each time a trigger occurs.

Attribute Summary:
Synchronization Required: no
Preset State: -10 dBm (100 mV)
SCPI Compliance: confirmed
Description:
Specifies a source output level that applies to all waveform types. For random noise or periodic
chirp, the level is the total wideband level (the summation of the waveform measured at full
span). For smaller spans, not all of the energy appears in the measurement because some of the
waveform’s power is outside the selected span. If the level is specified for random noise in Vrms,
when the source type is changed, the analyzer maintains the rms level for the new type. The
same is true for Vpk. Because the ratio of peak/rms varies for different signal types, the peak
value changes when the analyzer maintains the rms value. If a new rms value would require a
peak value outside the limits of the source voltage, the level is set to the limit. Limits are ±5 Vpk
and include offset as well as level. If no units are entered with the number, dBm are assumed.

Command Reference
For the Agilent 89441A, you can set the source output level as high as +23 dBm. However, the
output level for the Agilent 89441A is specified only to +13 dBm. Source performance is not
specified beyond +13 dBm. For additional details, see the specifications shipped with the
Agilent 89441A Installation & Verification Guide.
Notes
384
- It is good practice to specify the source level before the source is turned on.
When the source is turned on, the output voltage level is whatever value was
active when it was turned off. The active value may be large enough to damage
sensitive devices. At turn-on and preset, the level is −10 dBm (100 mV).
- Changing instrument mode does not turn the source off nor change the source
output value.

the front-panel keycodes.
The query returns the keycode for the last key pressed. If no keys have been pressed since the
last query, a −1 is returned.
Keys are encoded as follows:
0−127 are front-panel keys.
128−255 are shifted front-panel keys (never returned on query)
256−511 are interpreted as RPG (rotary pulse generator; knob) movement. The direction and
amount of movement is determined by <query value> − 384. So a query value of 386
represents 2 RPG ticks and a query value of 382 represents −2 RPG clicks.
*RST clears the queue of keys.

Notes
Sending block data to a data register is valid only if the data register contains
data. That is, you can only replace existing data in the data register. You cannot
transfer block data to an empty data register. For more information about
transferring block data, see the GPIB Programmer’s Guide, ‘’Block Parameters.’’
It is not possible to query Y-axis units – they depend on what measurement was
saved in the data register. In general, they are Vpk for spectrums and time traces,
Vpk2/Hz for PSD, and Vpk2 for correlation.
Trace data may be transferred directly to the controller with the LAN
file-transfer utility, FTP (option UG7). Data transferred with FTP is in Standard
Data Format (SDF).

Attribute Summary:
Synchronization Required: no
Preset State: 0%
SCPI Compliance: confirmed
Description:
If the trigger typs is internal channel (TRIG:SOUR INT1), the trigger level is entered as a percent
of the input range (VOLT:RANG).
If the trigger type is external trigger (TRIG:SOUR EXT), the trigger signal is connected to the
front panel connector labeled EXT TRIGGER and trigger level is entered in units of volts or %.
The level is an analog voltage between −11V and +11V or −110% to +110%.
If the trigger type is IF, the trigger level may be entered in units of volts, %, or dB.
Trigger level is not applicable for GPIB trigger (TRIG:SOUR BUS), source trigger (TRIG:SOUR
OUTP), or free run (TRIG:SOUR IMM).
Trigger level can be entered over GPIB in percentage or as a fraction. A query always returns the
fractional value. If the trigger type is external, the trigger level is entered in Volts and the
returned value is in volts. IF trigger also returns volts.
See TRIG:SOUR for more information.

Example Statements:
OUTPUT 719;"trigger:source INT1"
OUTPUT 719;"Trig:Source OUTP"
Query Syntax:
TRIGger:SOURce?
Return Format:
CHAR
Attribute Summary:
Synchronization Required: no
Preset State: IMM
SCPI Compliance: confirmed
Description:
The analyzer must be armed before triggering can occur. See ARM:SOUR.
IMM (immediate or free run) specifies that successive data blocks are to be taken as quickly as
possible without waiting for a trigger signal.
INT1|INT2 specifies that the input data blocks should be acquired when the channel (1|2)
sampled input data stream matches the trigger conditions (slope and level are set with
TRIG:SLOP and TRIG:LEV). Note that the second channel is an option and may not be installed
in the analyzer.
IF1|IF2 specifies the IF signal from either input channel 1 or 2 as the trigger signal. This means
the analyzer begins a measurement when the IF signal meets the specified trigger slope and level
conditions. IF trigger is a narrow-band trigger compared to the INT trigger. Some signal types
may require the use of trigger holdoff; see TRIG:HOLD. Note that the second channel is an
option and may not be installed in the analyzer.
OUTP specifies that the input data blocks should be acquired synchronously with the source.
BUS specifies that the input data blocks should be acquired when the GPIB Group Execute
Trigger command is received.
EXT specifies that the input data blocks are acquired when the front panel EXT TRIGGER signal
meets the level and slope criteria set with the TRIG:LEV and TRIG:SLOP commands. The level is
an analog voltage between −11.0V and +11.0V. Slope, in this case, indicates which side of the
level value the external signal must be to trigger a measurement (POS means ‘’more positive’’ and
NEG means ‘’more negative’’).
Note
456
Channel 2 is optional and may not be installed. If the second channel is not
installed, IF2 and INT2 generate error messages. If no number is used, “1" is
assumed.

Appendix A
Error Messages
SYSTem:ERRor?
The queue query message is a request for the next entry from the instrument’s error/event queue.
This queue contains an integer in the range [ -32768, 32767 ]. Negative error numbers are
reserved by the SCPI standard and defined in this document. Positive error numbers are
instrument-dependent. An error/event value of zero indicates that no error or event has occurred
(see next section, ‘’The queue’’).
The instrument responds to SYSTem:ERRor? query using the following form:
The <error/event number> is a unique error/event descriptor. Certain standard error/event
numbers are described in this document. The <error description> is a short description of the
error/event, (optionally) followed by further information about the error/event. Short
descriptions of the standard error/event numbers are given in this document.
The <device-dependent info> part of the response may contain information which allows you to
determine the exact error/event and context. For example,
-131, “Invalid suffix; FREQuency:CENT 2.0E+5 dBuV”
The maximum string length of <error description> plus <device-dependent information> is 255
characters.
The Error/Event Queue
As errors and events are detected, they are placed in a queue. This queue is first in, first out. If
the queue overflows, the last error/event in the queue is replaced with error
-350, “Queue overflow”
Any time the queue overflows, the least recent errors remain in the queue, and the most recent
error/event is discarded. Reading an error/event from the head of the queue removes that
error/event from the queue, and opens a position at the tail of the queue for a new error/event, if
one is subsequently detected.
When all errors/events have been read from the queue, further error/event queries return
0, ‘’No error’’
458
Appendix A
Error Messages
Individual erros and events may be enabled into the queue. The STATus:QUEue:ENABle
command accomplishes this. At STATus:PRESet, only errors are enabled. This means that both
SYSTem:ERRor? and STATus:QUEue[:NEXT]? report only errors unless the user changes the
neable mask.
The error/event queue is cleared when any of the following occur (IEEE 488.2, section 11.4.3.4):
Upon power up.
Upon receipt of a *CLS command.
Upon reading the last item from the queue.
Error numbers
The system-defined error/event numbers are chosen on an enumerated (“1 of N”) basis. The
SCPI-defined error/event numbers and the <error description> portions of the ERRor query
response are listed here. The first error/event described in each class (for example, -100, -200,
-300, -400) is a ‘’generic’’ error. In selecting the proper Error/event number to report, more
specific error/event codes are preferred, and the generic error/event is used only if the others are
inappropriate.
Note the organization of the following tables. A ‘’simple-minded’’ parser might implement only the
XX0 errors, and a smarter one might implement all of them. A ‘’smart and friendly’’ parser might
use the instrument-dependent part of the error/event message string to point out the offending
part of the command.
No Error
This message indicates that the device has no errors.

SCPI No-Error Description
No error. The queue is competely empty. Every error/event in the queue has been read or the queue was purposely

Appendix A
Error Messages
Command Error
An <error/event number> in the range [ -199 , -100 ] indicates that an IEEE 488.2 syntax error
has been detected by the instrument’s parser. The occurrence of any error in this class causes the
command error bit (bit 5) in the event status register (IEEE 488.2, section 11.5.1) to be set. One
of the following has occurred:
An IEEE 488.2 syntax error has been detected by the parser. That is, a controller-to-device
message was received which is in violation of the IEEE 488.2 standard. Possible violations
include a data element which violates the device listening formats or whose type is
unacceptable to the device.
An unrecognized header was received. Unrecognized headers include incorrect
device-specific headers and incorrect or unimplemented IEEE 488.2 common commands.
A Group Execute Trigger (GET) was entered into the input buffer inside of an IEEE 488.2
<PROGRAM MESSAGE>.
Events that generate command errors do not generate execution errors, device-specific errors, or
query errors; see the other error definitions in this chapter.
Error
Number
SCPI Command Error Descriptions
-100
Command error. This is the generic syntax error for devices that cannot detect more specific errors. This code
indicates only that a Command Error as defined in IEEE 488.2, 11.5.1.1.4 has occurred.
-101
Invalid character. A syntactic element contains a character which is invalid for that type; for example, a header
containing an ampersand, SETUP&. This error might be used in place of errors -114, -121, -141, and perhaps others.
-102
Syntax error. An unrecognized command or data type was encountered; for example, a string was received when the
device does not accept strings.
-103
Invalid separator. The parser was expecting a separator and encountered an illegal character; for example, the
semicolon was omitted after a program message unit, *EMC 1 :CH1:VOLTS 5.
-104
Data type error. The parser recognized a data element different than one allowed; for example, numeric or string data
was expected but block data was encountered.
-105
GET not allowed. A Group Execute Trigger was received within a program message (see IEEE 488.2, 7.7).
-108
Parameter not allowed. More parameters were received than expected for the header; for example, the *EMC common
command only accepts one parameter, so receiving *EMC 0,,1 is not allowed.
-109
Missing parameter. Fewer parameters were recieved than required for the header; for example, the *EMC common
command requires one parameter, so receiving *EMC is not allowed.
-110
Command header error. An error was detected in the header. This error message is used when the device cannot
detect the more specific errors described for errors -111 through -119.
-111
Header separator error. A character which is not a legal header separator was encountered while parsing the header;
for example, no white shace followed the header, thus *GMC"MACRO" is an error.
-112
Program mnemonic too long. The header contains more that twelve characters (see IEEE 488.2, 7.6.1.4.1).]
-113
Undefined header. The header is syntactically correct, but it is undefined for this specific device; for example, *XYZ is
not defined for any device.
-114

Error Messages
Execution Error
An <error/event number> in the range [ -299 ,, -200 ] indicates that an error has been detected by
the instrument’s execution control block. The occurrence of any error in this class causes the
execution error bit (bit 4) in the event status register (IEEE 488.2,, section 11.5.1) to be set. One
of the following events has occurred:
A <PROGRAM DATA> element following a header was evaluated by the device as outside of
its legal input range or is otherwise inconsistent with the device’s capabilities.
A valid program message could not be properly executed due to some device condition.
Execution errors are reported by the device after rounding and expression evaluation operations
have taken place. Rounding a numeric data element, for example, is not be reported as an
execution error. Events that generate execution errors do not generate Command Errors,
device-specific errors, or Query Errors; see the other error definitions in this section.

SCPI Execution Error Descriptions
-200
Execution error. This is the generic syntax error for devices that cannot detect more specific errors. This code
indicates only that an Execution Error as defined in IEEE 488.2, 11.5.1.1.5 has occurred.
-201
Invalid while in local. Indicates that a command is not executable while the device is in local due to a hard local control
(see IEEE 488.2, 5.6.1.5); for example, a device with a rotary switch receives a message which would change the
switches state, but the device is in local so the message can not be executed.
-202
Settings lost due to rtl. Indicates that a setting associated with a hard local control (see IEEE 488.2, 5.6.1.5) was lost
when the device changed to LOCS from REMS or to LWLS from RWLS.
-210
Trigger error
-211
Trigger ignored. Indicates that a GET, *TRG, or triggering signal was received and recognized by the device but was
ignored because of device timing considerations; for example, the device was not ready to respond. Note: a DT0 device
always ignores GET and treats *TRG as a Command Error.
-212
Arm ignored. Indicates that an arming signal was received and recognized by the device but was ignored.
-213
Init ignored. Indicates that a request for a measurement initiation was ignored as another measurement was already in
progress.
-214
Trigger deadlock. Indicates that the trigger source for the initiation of a measurement is set to GET and subsequent
measurement query is received. The measurement cannot be started until a GET is received, but the GET would cause
an INTERRUPTED error.
-215
Arm deadlock. Indicates that the arm source for the initiation of a measurement is set to GET and subsequent
measurement query is received. The measurement cannot be started until a GET is received, but the GET would cause
an INTERRUPTED error.

a common command header, or contained invalid header syntax.
-274
Macro parameter error. Indicates that the macro definition improperly used a macro parameter placeholder (see IEEE
488.2, 10.7.3).
-275
Macro definition too long. Indicates that a syntactically legal macro program data sequence could not be executed
because the string or block contents were too long for the device to handle (see IEEE 488.2, 10.7.6.1).

Device-Specific Error
An <error/event number> in the range [ -399 , -300 ] or [ 1 , 32767 ] indicates that the instrument
has detected an error which is not a command error, a query error, or an execution error; some
device operations did not properly complete, possibly due to an abnormal hardware or firmware
condition. These codes are also used for self-test response errors. The occurrence of any error in
this class causes the device-specific error bit (bit 3) in the event status register (IEEE 488.2,
section 11.5.1) to be set. The meaning of positive error codes is device-dependent and may be
enumerated or bit mapped; the <error message> string for positive error codes is not defined by
SCPI and available to the device designer. Note that the string is not optional; if the designer does
not wish to implement a string for a particular error, the null string is be sent (for example, 42,"").
The occurrence of any error in this class causes the device-specific error bit (bit 3) in the event
status register (IEEE 488.2, section 11.5.1) to be set. Events that generate device-specific errors
do not generate command errors, execution errors, or query errors; see the other error definitions
