Command Syntax
Command and Query Structure
A quantity, quality, restriction, or limit associated with the
header. Not all commands have an argument, while other
commands have multiple arguments. Arguments are
separated from the header by a <Space>. Arguments are
separated from each other by a <Comma>.
Commands consist of set commands and query commands (usually
simply called commands and queries). Commands change instrument
settings or perform a specific action. Queries cause the oscilloscope
to return data and information about its status.
<Argument>
Most commands have both a set form and a query form. The query
form of the command is the same as the set form except that it ends
with a question mark. For example, the set command ACQuire:MODe
has a query form ACQuire:MODe?. Not all commands have both a set
and a query form; some commands are set only and some are query
only.
A header subfunction. Some command headers have only
one mnemonic. If a command header has multiple
mnemonics, they are always separated from each other by
a colon (:) character.
A few commands do both a set and query action. For example, the
*CAL? command runs a self-calibration program on the oscilloscope,
then returns the result of the calibration.
<Mnemonic>
A command message is a command or query name, followed by any
information the oscilloscope needs to execute the command or query.
Command messages consist of five different element types, which
are defined in Table 2–2 and shown in Figure 2–1.
The basic command name. If the header ends with a
question mark, the command is a query. The header may
begin with a colon (:) character; if the command is
concatenated with other commands the beginning colon is
required. The beginning colon can never be used with
command headers beginning with a star (*).

off of the previous one. Commands at a higher level in the tree may
affect those at a lower level. The leading colon (:) always returns you

You can control whether the instrument returns headers as part of the
query response. Use the HEADer command to control this feature. If
header is on, the instrument returns command headers as part of the
query and formats the query response as a valid set command. When
header is off, the instrument sends back only the values in the
response. This format can make it easier to parse and extract the
information from the response. Table 2–3 shows the difference in

Clearing the Output Queue
To clear the output queue and reset the oscilloscope to accept a new
command or query, send a Device Clear (DCL) from a GPIB host or
a break signal from an RS-232 host.
Command Entry
Follow these general rules when entering commands:
H Enter commands in upper or lower case.
H You can precede any command with white space characters.
White space characters include any combination of the ASCII
control characters 00 through 09 and 0B through 20 hexadecimal
(0 through 9 and 11 through 32 decimal).
H The oscilloscope ignores commands that consists of just a
combination of white space characters and line feeds.
Abbreviating Commands
You can abbreviate many oscilloscope commands. These abbreviations are shown in capital letters in the command listing in the
Command Groups section on page 2–15 and Command Descriptions
section on page 2–33. For example, the command ACQuire:NUMAvg
can be entered simply as ACQ:NUMA or acq:numa.
If you use the HEADer command to have command headers included
as part of query responses, you can also control whether the returned
headers are abbreviated or are full-length using the VERBose
command.

Concatenating Commands
CH1:COUPling?;BANdwidth?
You can concatenate any combination of set commands and queries
using a semicolon (;). The oscilloscope executes concatenated
commands in the order received. When concatenating commands and
queries you must follow these rules:
H When you concatenate queries, the responses to all queries are
combined into a single response message. For example, if
channel 1 coupling is set to DC and the bandwidth is set to
20MHz, the concatenated query:
H Completely different headers must be separated by both a
semicolon and by the beginning colon on all commands but the
first. For example, the commands TRIGger:MODe NORMal and
ACQuire:NUMAVg 16 can be concatenated into a single command:
sets the acquisition mode to average and sets acquisition
averaging to 16. The *TRG command is ignored.
TRIGger:MODe NORMal;:ACQuire:NUMAVg 16
ACQuire:MODe AVErage;*TRG;NUMAVg 16
H If concatenated commands have headers that differ by only the
last mnemonic, you can abbreviate the second command and
eliminate the beginning colon. For example, the commands
ACQuire:MODe AVErage and ACQuire:NUMAVg 16 could be
concatenated into a single command:
The instrument processes commands that follow the star
command as if the star command was not there, so:
ACQuire:MODe AVErage; NUMAVg 16
ACQuire:MODe AVErage;*TRG
The longer version works equally well:
H Never precede a star (*) command with a colon:
ACQuire:MODe AVErage;:ACQuire:NUMAVg 16
ACQuire:MODe AVErage;:ACQuire:NUMAVg 16
H Never precede a star (*) command with a colon:

is a valid message that sets the acquisition mode to normal,
queries the number of acquisitions for averaging, and then queries
the acquisition state. The oscilloscope executes concatenated
commands and queries in the order it receives them.
H Any query that returns arbitrary data, such as ID?, must be the
last query when part of a concatenated command. If the query is
not last, the oscilloscope generates event message 440.

Message Terminators
This manual uses the term <EOM> (End of message) to represent a
message terminator.
GPIB End of Message Terminators. GPIB EOM terminators can be the
END message (EOI asserted concurrently with the last data byte), the
ASCII code for line feed (LF) sent as the last data byte, or both. The
oscilloscope always terminates messages with LF and EOI. White
space is allowed before the terminator; for example, CR LF is
acceptable.

Follow these rules when you use quoted strings:
1. A quoted string can include any character defined in the 7-bit
ASCII character set. Refer to Appendix A.
2. Use the same type of quote character to open and close the string:
"this is a valid string"
3. You can mix quotation marks within a string as long as you
follow the previous rule:
"this is an 'acceptable' string"
4. You can include a quote character within a string simply by
repeating the quote. For example,
"here is a "" mark"
5. Strings can have upper or lower case characters.
6. If you use a GPIB network, you cannot terminate a quoted string
with the END message before the closing delimiter.
7. A carriage return or line feed embedded in a quoted string does
not terminate the string, but is treated as just another character in
the string.
8. The maximum length of a quoted string returned from a query is
1000 characters.
Here are some examples of invalid strings:
"Invalid string argument'
(quotes are not of the same type)
"test<EOI>"

Save and Recall Commands
Save and Recall commands allow you to store and retrieve internal
waveforms and settings. When you “save a setting,” you save most
of the settings of the oscilloscope. When you then “recall a setting,”
the oscilloscope restores itself to the state it was in when you saved
that setting.
To display a saved waveform, use the SELect:<wfm> command
described on page 2–138.

Waveform commands let you transfer waveform data points to and
from the oscilloscope. Waveform data points are a collection of
values that define a waveform. One data value usually represents one
data point in the waveform record. When working with peak-detect
waveforms, each data value is either the min or max of a min/max
pair. Before you can transfer waveform data, you must specify the
data format and waveform locations.

Waveform Data Formats
Waveform data uses one 8-bit data byte to represent each data point,
regardless of the acquisition mode.
For compatibility with earlier digitizing oscilloscopes, the
DATa:WIDth command lets you specify the number of bytes per data
point when transferring data to and from the oscilloscope. If you
specify two bytes for data that uses only one, the least significant
byte will be filled with zeros. The oscilloscope ignores the
least-significant byte of incoming waveforms.
The oscilloscope can transfer waveform data in either ASCII or
binary format. Use the DATa:ENCdg command to specify one of the
following formats:
CURVE<space>Ć110,Ć109,Ć110,Ć110,Ć109,Ć107,Ć109,Ć107,
Ć106,Ć105,Ć103,Ć100,Ć97,Ć90,Ć84,Ć80
An example of an ASCII waveform data string follows:
Each data value requires two to seven characters. This includes
one character for the minus sign if the value is negative, one to
five ASCII characters for the waveform value, and a comma to
separate data points.
H ASCII data is represented by signed integer values. The range of
values depends on the byte width specified. One-byte-wide data
ranges from -128 to 127. Two-byte-wide data ranges from -32768
to 32767.
H ASCII data is represented by signed integer values. The range of
values depends on the byte width specified. One-byte-wide data
ranges from -128 to 127. Two-byte-wide data ranges from -32768
to 32767.

You can transfer multiple points for each waveform record. You can
transfer a portion of the waveform or you can transfer the entire
record. The DATa:STARt and DATa:STOP commands let you specify
the first and last data points of the waveform record.
Table 2–18: Binary data ranges
When transferring data into the oscilloscope you must specify the
location of the first data point within the waveform record. For
example, when DATa:STARt is set to 1, data points will be stored
starting with the first point in the record, and when DATa:STARt is
set to 500, data will be stored starting at the 500th point in the record.
The oscilloscope ignores DATa:STOP when reading in data as the
oscilloscope will stop reading data when there is no more data to
read or when it has reached 2500 data points.
H Binary data can be represented by signed integer or positive
integer values. The range of the values depends on the byte width
specified. Table 2–18 lists the ranges for one- and two-byte-wide
data.
Waveform Data Record
The defined binary formats also specify the order in which the
bytes are transferred giving a total of four binary formats:
RIBinary, RPBinary, SRIbinary, and SRPbinary.
RIBinary is signed integer where the most significant byte is
transferred first, and RPBinary is positive integer where the most
significant byte is transferred first. SRIbinary and SRPbinary
correspond to RIBinary and RPBinary respectively but use a
swapped byte order where the least significant byte is transferred
first. The byte order is ignored when DATa:WIDth is set to 1.

Waveform Data Locations and Memory Allocation
The DATa:SOUrce command specifies the location of the data when
transferring waveforms from the oscilloscope. You can transfer one

You can transfer only one waveform into the oscilloscope at a time.
Each waveform sent to the oscilloscope is stored in one of two stored
waveform locations. You specify the stored waveform location with
the DATa:DESTination command.
NOTE. The oscilloscope accepts waveforms that are v2500 data
points long. The oscilloscope truncates waveforms longer than 2500
data points.
Waveform Preamble
Each waveform that is transferred has an associated waveform
preamble that contains information such as the horizontal scale,
vertical scale, and other settings in place when the waveform was
created. Refer to the WFMPre commands starting on page 2–157 for
more information about the waveform preamble.
Scaling Waveform Data
Once you transfer the waveform data to the controller, you can
convert the data points into voltage values for analysis using
information from the waveform preamble.

NOTE. While trigger view is active (by pushing the TRIGGER VIEW
button on the front panel), the oscilloscope ignores the set form of
most commands. If you send a command at this time the oscilloscope
generates execution error 221 (Settings conflict).
The syntax of some commands varies, depending on which extension
module and oscilloscope you are using. The differences are noted.
This manual fully spells out headers, mnemonics, and arguments
with the minimal spelling shown in upper case. For example, to use
the abbreviated form of the ACQuire:MODe command just type
ACQ:MOD.

ACQuire:MODe
Waveforms are the displayed data point values taken from acquisition intervals. Each acquisition interval represents a time duration
that is determined by the horizontal scale (time per division).
The acquisition mode, which you set using this ACQuire:MODe
command, determines how the final value of the acquisition interval
is generated from the many data samples.
The oscilloscope sampling system can operate at a rate greater than
that indicated by the horizontal scale. Therefore an acquisition
interval can include more than one sample.

If MEASUrement:MEAS<x>:TYPe is set to NONE, MEASUrement:MEAS<x>:VALue? generates event message 2231 (Measurement error, measurement is not turned on) and returns 9.9E37.
This value is a display value and will be updated about every 1/2
second if both the MEASURE menu and the MEAS<x> source
channel are displayed. If you are acquiring at a slow sweep rate, the
oscilloscope may take longer than 1/2 second to update. MEASurement:IMMED is usually more useful than MEASUrement:MEAS<x>
when using the oscilloscope with external devices.
Returns the value that has been calculated for the oscilloscope
measurement specified by <x>.

Status and Events
The oscilloscope provides a status and event reporting system for the
GPIB and RS-232 interfaces. This system informs you of certain
significant events that occur within the oscilloscope.
The oscilloscope status reporting system consists of five 8-bit
registers and two queues. This section describes these registers and
components, and explains how the event handling system operates.
Registers
The registers in the event reporting system fall into two functional
groups:
H The Standard Event Status Register (SESR) and the Status Byte
Register (SBR) contain information about the status of the
oscilloscope. These registers are the Status Registers.
H The Device Event Status Enable Register (DESER), the Event
Status Enable Register (ESER), and the Service Request Enable
Register (SRER) determine whether selected types of events are
reported to the Status Registers and the Event Queue. These three
registers are the Enable Registers.
Status Registers
The Standard Event Status Register (SESR) and the Status Byte
Register (SBR) record certain types of events that may occur while
the oscilloscope is in use. IEEE Std 488.2-1987 defines these
registers.
Each bit in a Status Register records a particular type of event, such
as an execution error or service request. When an event of a given
type occurs, the oscilloscope sets the bit that represents that type of
event to a value of one. (You can disable bits so that they ignore
events and remain at zero. See the Enable Registers section on
page 3–4.) Reading the status registers tells you what types of
events have occurred.

Enable Registers
The DESER, ESER, and SRER allow you to select which events are
reported to the Status Registers and the Event Queue. Each Enable
Register acts as a filter to a Status Register (the DESER also acts as a
filter to the Event Queue) and can prevent information from being
recorded in the register or queue.
Each bit in an Enable Register corresponds to a bit in the Status
Register it controls. In order for an event to be reported to its bit in
the Status Register, the corresponding bit in the Enable Register must
be set to one. If the bit in the Enable Register is set to zero, the event
is not recorded.

The bits in the Enable Registers are set using various commands.
The Enable Registers and the commands used to set them are
described below.
Figure 3–3: The Device Event Status Enable Register (DESER)
Each bit in an Enable Register corresponds to a bit in the Status
Register it controls. In order for an event to be reported to its bit in
the Status Register, the corresponding bit in the Enable Register must
be set to one. If the bit in the Enable Register is set to zero, the event
is not recorded.
The DESER, ESER, and SRER allow you to select which events are
reported to the Status Registers and the Event Queue. Each Enable
Register acts as a filter to a Status Register (the DESER also acts as a
filter to the Event Queue) and can prevent information from being
recorded in the register or queue.

The Enable Registers and the *PSC Command
The *PSC command controls the contents of the Enable Registers at
power on. Sending *PSC 1 sets the Enable Registers at power on as
follows:
H DESER 255 (equivalent to a DESe 255 command)
The Output Queue stores query responses waiting to be output. The
oscilloscope empties the Output Queue each time it receives a new
command or query message. This means you must read any query
response before you send the next command or query, or you will
lose responses to earlier queries. Also, an error may result.
H ESER 0 (equivalent to an *ESE 0 command)
The Output Queue
H SRER 0 (equivalent to an *SRE 0 command)
The oscilloscope status and event reporting system contains two
queues: the Output Queue and the Event Queue.
Sending *PSC 0 lets the Enable Registers maintain their values in
nonvolatile memory through a power cycle.
Queues
NOTE. To enable the PON (Power On) event to generate a Service
Request (GPIB only), send *PSC 0, use the DESe and *ESE
commands to enable PON in the DESER and ESER, and use the
*SRE command to enable bit 5 in the SRER. Subsequent power-on
cycles will generate a Service Request (GPIB only).
NOTE. To enable the PON (Power On) event to generate a Service

Status and Events
NOTE. When a controller sends a query, an <EOM>, and a second
query, the digitizing oscilloscope normally clears the first response
and outputs the second while reporting a Query Error (QYE bit in the
ESER) to indicate the lost response. A fast controller, however, may
receive a part or all the first response as well. To avoid this situation,
the controller should always read the response immediately after
sending any terminated query message or send a DCL (Device Clear)
before sending the second query.
The Event Queue
The Event Queue stores detailed information on up to 20 events. If
more than 20 events stack up in the Event Queue, the 20th event is
replaced by event code 350, “Too many events.”
Read the Event Queue with EVENT? (which returns only the event
number), with EVMsg? (which returns the event number and a text
description of the event), or with ALLEV? (which returns all the
event numbers along with a description of the event). Reading an
event removes it from the queue.
Before reading an event from the Event Queue, you must use *ESR?
to read the summary of the event from the SESR. This makes the
events summarized by *ESR? available to EVENT? and EVMSG?,
and empties the SESR.
Reading the SESR erases any events that were summarized by
previous *ESR? reads but not read from the Event Queue. Events
that follow an *ESR? read are put in the Event Queue, but are not
available until *ESR? is used again.

Synchronization Methods
The acquisition of the waveform requires extended processing time
and may not complete before the amplitude measurement is taken.
(See Figure 3–7.) This will result in an incorrect peak-to-peak value.
Although most commands are completed almost immediately after
being received by the oscilloscope, some commands start a process
that requires more time. For example, once a HARDCOPY START
command is executed, it may be a few seconds before the hardcopy
operation is complete. Rather than remain idle while the operation is
in process, the oscilloscope continues processing other commands.
This means that some operations are not completed in the order that
they were sent.
MEASUREMENT:IMMED:VALUE?
There may be times when the result of an operation is dependent on
the result of an earlier one, and you must be assured that the first
operation has completed before processing the next one. The status
and event reporting system provides ways to do this.
/** Take peak-to-peak measurement on acquired data **/
For example, a typical application would be to acquire a single-sequence waveform, and then take a measurement on the acquired
waveform. You could use the following command sequence:
MEASUREMENT:IMMED:SOURCE CH1
/** Set up single-sequence acquisition **/
MEASUREMENT:IMMED:TYPE PK2PK

The controller can continue to write commands to the input buffer,
but the commands are not processed by the oscilloscope until all

*OPC? places a 1 in the Output Queue once an operation is
complete. A timeout could occur if you try to read the output queue
before there is any data in it.
*OPC?
The same command sequence using *OPC? for synchronization
follows:
/* Wait until the acquisition is complete before taking the
measurement */

Status and Events
Messages
Tables 3–3 through 3–9 list all the programming interface messages
the oscilloscope generates in response to commands and queries.
Each message is the result of an event. Each type of event sets a
specific bit in the SESR and is controlled by the equivalent bit in
the DESER. Thus, each message is associated with a specific SESR
bit. In the message tables that follow, the associated SESR bit is
specified in the table title, with exceptions noted with the error
message text.
Table 3–3 shows the messages when the system has no events or
status to report. These have no associated SESR bit.

oscilloscope using ASCII character encoding.
Address
A 7-bit code that identifies an instrument on the communication
bus. The digitizing oscilloscope must have a unique address for
the controller to recognize and transmit commands to it.
Backus-Naur Form (BNF)
A standard notation system for command syntax. The syntax in
this manual use BNF notation.
Controller
A computer or other device that sends commands to and accepts
responses from the digitizing oscilloscope.
EOI
A mnemonic referring to the control line “End or Identify” on
the GPIB interface bus. One of the two possible end-of-message
terminators.
EOM
A generic acronym referring to the end-of-message terminator.
The end-of-message terminator is either an EOI or the ASCII
code for line feed (LF).
IEEE
Acronym for the Institute of Electrical and Electronics
Engineers.
