5 Operating principle
Frontend
Starting from the antenna socket, the frequency in the signal path is limited to 8 GHz.
Signal processing then takes place in three paths for three different frequency
ranges. Signals from 9 kHz to 30 MHz are routed via a preamplifier directly to the A/D
converter. Signals from 20 MHz to 3.5 GHz are taken to the IF section via a
preselection and a preamplifier, or via an attenuator in the case of high signal levels.
The preselection as well as the attenuator effectively protect the IF section against
overloading. This is particularly important in this frequency range, where the
maximum signal sum levels occur. Signals from 3.5 GHz to 8 GHz are taken to the IF
section via a preamplifier. The three-stage IF section processes the signals from 20
MHz to 8 GHz for the subsequent A/D converter. To provide optimum instrument
performance, only signals up to 7.5 GHz are processed in the subsequent stages.
The uncontrolled 21.4 MHz IF can also be tapped ahead of the A/D converter via a
BNC socket of the R&S®PR100 for further external processing.
Digital signal processing
After A/D conversion of the signal, the signal path is split up: In the first path, the IF
spectrum is calculated by means of a digital downconverter (DDC), a digital
bandpass filter and an FFT stage. The bandwidth of the bandpass filter can be
selected between 10 kHz and 10 MHz. Before the IF spectrum is output on the
display or via the LAN interface, results are postprocessed by means of the
AVERAGE, MIN HOLD or MAX HOLD function as selected by the user. In the
second path, the signal is processed for level measurement or demodulation. Here,
too, the signal is taken via a DDC and a bandpass filter. To process the different
signals with optimum signal-to-noise ratio, the receiver contains IF filters with
demodulation bandwidths from 150 Hz to 500 kHz, which can be selected
independently of the IF bandwidth. Prior to the level measurement, the absolute
value of the level is determined and weighted by means of the AVERAGE, MAX
PEAK, RMS or SAMPLE function, as selected by the user. The measured level is
then output on the display or via the LAN interface. For the demodulation of analog
signals, the complex baseband data is subjected to automatic gain control (AGC) or
manual gain control (MGC) after the bandpass filter. It is then applied to the AM, FM,
USB, LSB, ISB, PULSE or CW demodulation stage. The complex baseband data (I/Q
data) of digital signals is directly output for further processing after the AGC/MGC
stage.
The results obtained are available as digital data and can be output via the LAN
interface as required for the particular task. Digital audio data are reconverted to
analog signals for output via the loudspeaker.
R&S PR100
User Manual
High receiver sensitivity, high signal resolution
The R&S® PR100 features an IF bandwidth of up to 10 MHz. This allows even very
short signal pulses to be captured since the receiver displays the large bandwidth of
10 MHz in a single spectrum about the set center frequency without any scanning
being required. The widest IF bandwidth of 10 MHz yields the widest spectral display;
the narrowest IF bandwidth of 10 kHz yields maximum sensitivity. The IF spectrum is
digitally calculated by means of a Fast Fourier Transform (FFT). The use of FFT
computation at the IF offers a major advantage: The receiver sensitivity and signal
resolution are clearly superior to those of a conventional analog receiver at the same
spectral display width.
IF spectrum
FFT calculation of the IF spectrum is performed in a number of steps. These are
described below in simplified form for an IF bandwidth of 10 kHz (BWIF spectrum =
10 kHz), which yields maximum sensitivity. Due to the finite edge steepness of the IF
filter, the sampling rate fs must be larger than the selected IF bandwidth BWIF
spectrum. The quotient of the sampling rate and the IF bandwidth is thus a value >1
and is a measure of the edge steepness of the IF filter. This relationship is expressed
by the following two formulas:
fs
= const
BIFspectrum
or
f s = BWIFspectrum * const
The value of the constant is dependent on the selected IF bandwidth, i.e. it may vary
as a function of the IF bandwidth. For an IF bandwidth of BWIF spectrum = 10 kHz,
the constant has a value of 1.28. To display a 10 kHz IF spectrum, therefore, a
sampling rate of fs = 12.8 kHz is required.
R&S PR100
User Manual
The R&S®PR100 uses an FFT length N of 2048 points to generate the IF spectrum.
To calculate these points, the 12.8 kHz sampling band in the above example is
divided into 2048 equidistant frequency slices, which are also referred to as “bins”
(see figure "Signal processing for IF spectrum"). The bandwidth BWbin of the
frequency slices is obtained as follows:
BWbin =
fs
12.8kHz
=
= 6.25 Hz
2048
2048
This means that in the above example only the calculated bandwidth of 6.25 Hz for
each bin has to be taken into account as the noise bandwidth in the calculation of the
displayed average noise level (DANL) in accordance with the formula below (the
effect of the window function (Blackman window) of the FFT is not considered here
for simplicity's sake):
DANL = 174dBm + NF + 10 * log( BWbin / Hz )
The quantity NF represents the overall noise figure of the receiver. The above
example shows that, due to the use of the FFT, the actual resolution bandwidth
(RBW) to be taken into account in DANL calculation is clearly smaller (i.e. BWbin)
than would be expected for the wide display range of 10 kHz. Another advantage of
the high spectral resolution used in the FFT calculation is that signals located close
together (e.g. f1, f2, f3) can be captured and represented in the IF spectrum as
discrete signals (see figure "Signal display in IF spectrum"). If, on an analog receiver,
a resolution bandwidth equal to the set IF bandwidth were selected (RBW = BWIF
spectrum), a sum signal fsum would be displayed instead of the three discrete
signals f1, f2 and f3.

User Manual

Signal resolution in IF spectrum with digital and analog receiver concept
Panorama scan
The receiver's maximum FFT bandwidth of 10 MHz makes it possible to perform
extremely fast scans across a wide frequency range (panorama scan). For this
purpose, frequency windows of max. 10 MHz width are linked in succession, and
thus the complete, predefined scan range is traversed (see figure "Signal processing
in panorama scan mode"). Same as with the IF spectrum, an FFT is used to process
the broad window with a finer resolution. The width of the frequency window and the
FFT length (number of FFT points) are variable and are selected by the receiver. In
the panorama scan mode, the user can select among 12 resolution bandwidths from
125 Hz to 100 kHz. The resolution bandwidth corresponds to the width of the
frequency slices (bin width) mentioned under "IF spectrum" above. Based on the
selected bin width and start and stop frequency, the R&S®PR100 automatically
determines the required FFT length and the width of the frequency window for each
scan step. The receiver selects these internal parameters so that the optimum scan
speed is achieved for each resolution bandwidth (see figure "Resolution in panorama
scan mode").

User Manual
6.5 Inserting the battery
The R&S PR100 is fitted with a lithium ion battery.
The HA-Z206 battery pack has a charging capacity of 6.75 Ah.
The battery is inserted into the bottom right of the instrument.
The cover must first be pulled downwards to unlock it and then folded upwards to
open it.
The battery is NOT fitted in the R&S PR100 on delivery and must therefore be fitted
before the device can be used for the first time.
6.6 Connecting to the power supply
The R&S PR100 can be powered using the mains power adaptor or the internal
battery supplied. When fully charged, the built-in lithium ion battery permits approx.
3.5 hours of operation. When the R&S PR100 is delivered, the battery may be
completely discharged. Should you wish to use it without a mains power connection
you will therefore need to charge it. Charging time is approx. 3.5 hours with the
device switched off. During operation using mains power, the R&S PR100
simultaneously charges the internal battery. Insert the power adaptor plug into the
POWER ADAPTOR socket on the left-hand side of the device until it clicks into
place. Then connect the adaptor to the mains power socket.
The adapter voltage range is 100 V to 240 V AC / 50 Hz to 60 Hz.
The PR100's DC supply range is +15 V DC +/-10%, max. 2 A
R&S PR100
Caution!
User Manual
The R&S HA-Z201 power adaptor supplied should only be
used to operate the device or to charge the battery using
mains power.
Ensure that the mains supply voltage is compatible with
the voltage specified on the adaptor before use. Attach the
appropriate connector before inserting the adaptor into the
AC power outlet.
6.7 Charging the Battery
The R&S PR100 is equipped with a lithium ion battery. The battery permits
approximately 3.5 hours' operation at room temperature when it is fully charged.
Caution!
On delivery, the R&S PR100's battery is not fully
charged. The battery therefore needs to be charged
before the device can be used for the first time.
If the unit is stored for an extended period, self-discharge will reduce the battery's
charge. The battery should therefore be charged before use if it is intended to be the
sole power source for an extended period.
The charge status of the battery pack is shown on the instrument's display.
The battery can either be charged directly in the instrument by using the supplied
adaptor or with the optional external R&S HA-Z203 battery charger. Charging takes
approx. 7 hours with the device switched on.
For faster charging, switch off the instrument during charging. Charging takes
approx. 3.5 hours with the device switched off or by using the external charging unit.

8 SCPI Interface
8.1 Document Outline
The SCPI standard describes an interface with which instruments can be
controlled. The idea behind SCPI is that it should not matter what kind of
instrument measures e.g. a voltage level, be it a multimeter or a radio scanner
measuring the voltage at the antenna output; the command should always be
the same. Although theoretically possible, in practice this goal in
unachievable. However, the goal of every instrument designer is to stay as
close to SCPI as possible.
The goal of every instrument designer is to stay as close to SCPI as possible.
In addition, the PR100 tries to be backward compatible with its predecessor,
the EB200 Miniport Receiver, when possible. In fact, this compatibility
requirement outweighs the SCPI compliance requirement. Therefore, the
SCPI interface for the PR100 is defined with the following rules:
1. If an EB200 SCPI command relates to functionality that is not
supported by the PR100, the command is not supported either.
2. If a function can be done via an existing EB200 SCPI command, that
command is supported.
3. If a function cannot be done via an existing EB200 SCPI command, but
a suitable SCPI compliant command is available, the SCPI compliant
command is supported.
4. Otherwise, a new SCPI-like command is added, specific for the PR100
Each command is described in detail in Chapter 11.
A command is rarely useful if no data can be retrieved to monitor its effect. In
SCPI, this is done via queries. Queries can be used to retrieve the settings of
an instrument. However, measurements can consist of large sets of data.
Outputting that over the SCPI interface could delay the reaction time to
commands, which is why the PR100 also offers the data in another format that
can be sent via the UDP/IP protocol (internet).

9 SCPI Commands
9.1 SCPI introduction
SCPI (Standard Commands for Programmable Instruments) describes a
standard command set for programming devices, irrespective of the type of
device or manufacturer. The goal of the SCPI consortium is to standardize the
device-specific commands to a large extent. For this purpose, a model was
developed that defines the same functions for different devices. Command
systems were generated that are assigned to these functions. Thus it is
possible to address the same functions with identical commands. The
command systems are of a hierarchical structure. Figure 1 illustrates this tree
structure using a section of command system SENSe which operates the
sensor functions of the devices. The other examples regarding syntax and
structure of the commands are derived from this command system.
SCPI is based on standard IEEE 488.2, i.e. it uses the same syntactic
elements as well as the common commands defined in this standard. Part of
the syntax of the device responses is defined with greater restrictions than in
standard IEEE 488.2 (see Section 9.1.4).
The commands consist of a so-called header and, in most cases, one or more
parameters. Header and parameter are separated by a "white space" (= any
number of space characters, ASCII code 32 decimal). The headers may
R&S PR100
User Manual
consist of several keywords. Queries are formed by directly appending a
question mark to the header.
9.1.1 Common Command Structure
Common commands consist of a header preceded by an asterisk "*" and one
or several parameters, if any.
Examples:
*RST
RESET, resets the device
*ESE 253
EVENT STATUS ENABLE, sets the bits of the event status
enable register to 253
*ESR?
EVENT STATUS QUERY, queries the contents of the
event status register.
9.1.2 Device-Specific Command Structure
Hierarchy
Device-specific commands are of hierarchical structure (see Figure 1).
Commands of the highest level (root level) consist of only one keyword. This
keyword denotes a complete command system.
Example:
SYSTem
This keyword denotes the command system SYSTem.
For commands of lower levels, the complete path has to be specified, starting
on the left with the highest level, the individual keywords being separated by a
colon ":".
Example:
SENSe:FREQuency:STARt 118 MHz
This command lies in the third level of the SENSe system. It sets the
starting frequency of a scan to 118 MHz.

Keywords that occur at several levels within one command system can have
different effects.
Example:
MMEMory:CATalog?
List all files in the current directory.
R&S PR100
User Manual
DISPlay:WINDow:CATalog?
List all available display modes.
Optional keywords
Some command systems permit certain keywords to be optionally inserted
into a command or omitted. These keywords are marked by square brackets
in the description. Some commands are considerably shortened by these
optional keywords, although the full command length is also recognized by the
device.
Example:
Command description:
FORMat[:DATA] ASCii
Full command:
FORMat ASCii
Shortened command:
FORM ASC
Note: An optional keyword must not be omitted if its effect is specified in detail
by a numeric suffix.
Long and short form
The keywords can be of a long form or a short form. Either the short form or
the long form can be entered, other abbreviations are not permissible.
Example:
Long form: STATus:QUEStionable:ENABle 1
Short form: STAT:QUES:ENAB 1
Note: The short form is marked by upper-case letters, the long form
corresponds to the complete word. Upper-case and lower-case notation only
serve the human reader, the device itself does not make any difference
between upper- and lower-case letters.
Parameter
The parameter must be separated from the header by a "white space". If
several parameters are specified in a command, they are separated by a
comma ",". A few queries permit the parameters MINimum, MAXimum and
DEFault to be entered. For a description of the types of parameter, refer to
"Parameters" in Section 9.1.5.
Example:
DISPlay:BRIGhtness? MAXimum
Response: 1.00
This query requests the maximal value for the display backlight.
Numeric Suffix
If a device features several functions or characteristics of the same kind, the
desired function can be selected by a suffix added to the command. Entries
without suffix are interpreted like entries with the suffix 1.
9.1.3 Structure of a command line
Several commands in a line are separated by a semicolon ";". If the next
command belongs to a different command system, the semicolon is followed
by a colon.
Example:
DISPlay:BRIGhtness MAXimum;:SYSTem:AUDio:VOLume MAXimum
R&S PR100
User Manual
This command line contains two commands. The first command is part
of the DISPlay system and is used to specify the level of the display
backlight. The second command is part of the SYSTem system and
sets the audio volume to maximum.
If the successive commands belong to the same system, having one or
several levels in common, the command line can be abbreviated. To this end,
the second command after the semicolon starts with the level that lies below
the common levels (see also Figure 1). The colon following the semicolon
must be omitted in this case.
Example:
DISPlay:BRIGhtness MAXimum;:DISPlay:DATE:FORMat ddmmyyyy
This command line is represented in its full length and contains two
commands separated from each other by the semicolon. Both
commands are part of the DISPlay command system, ie they have one
level in common.
When abbreviating the command line, the second command begins
with the level below DISPlay. The colon after the semicolon is omitted.
The abbreviated form of the command line reads as follows:
DISPlay:BRIGhtness MAXimum;DATE:FORMat ddmmyyyy
However, a new command line always begins with the complete path.
Example:
DISPlay:BRIGhtness MAXimum
DISPlay:BRIGhtness 0.5
9.1.4 Responses to queries
A query is defined for each setting command unless explicitly specified
otherwise. It is formed by adding a question mark to the associated setting
command. According to SCPI, the responses to queries are partly subject to
stricter rules than in standard IEEE 488.2.
1. Maximum values, minimum values and all further quantities, which are
requested via a special text parameter are returned as numerical
values.
Example:
SENSe:FREQuency:STARt? MIN
Response: 9000
2. Numerical values are output without a unit. Physical quantities are
referred to the basic units.
Example:
SENSe:FREQuency:STOP?
Response:
100000000 for 100 MHz
3. Truth values <Boolean values> are returned as 0 (for OFF) and 1 (for
ON).
Example:
OUTPut:IF:STATe?
Response: 1
4. Text (character data) is returned in a short form (see also "Parameters"
on page 10).
R&S PR100
User Manual
Example:
SWAPped
FORMat:BORDer?
Response:
9.1.5 Parameters
Most commands require a parameter to be specified. The parameters must be
separated from the header by a "white space". Permissible parameters are
numerical values, Boolean parameters, text, character strings, block data and
expressions. The type of parameter required for each command and the
permissible range of values are specified in the command description (see
Section 9.4).
Numerical values
Numerical values can be entered in several forms, i.e. with sign, decimal point
and exponent. Values exceeding the resolution of the device are rounded.
The mantissa may comprise up to 41 characters, the exponent must lie inside
the value range -37 to 37. The exponent is introduced by an "E" or "e". Entry
of the exponent alone is not permissible. In the case of physical quantities, the
unit can be entered. Permissible units are as follows:
• for frequencies
GHz, MHz or MAHz, kHz and Hz, default
unit is Hz
• for times
s, ms, Zs, ns; default unit is s
• for levels
dBZV; default unit is dBZV
• for percentage
PCT, default unit PCT
If the unit is missing, the default unit is used. Note that mHz (milli Hz) as a unit
is not used to avoid confusion with MHz (mega Hz) since SCPI is case
insensitive.
Example:
SENSe:FREQuency:STARt 123 MHz = SENSe:FREQuency:STARt 123E6
Special numerical
The texts MIN, MAX, UP, DOWN, INF, NINF, and NAN are interpreted as
special numerical values. In the case of a query, the numerical value is
provided.
Example:
Command: SENSe:FREQuency:STARt MINimum
Query:
SENSe: FREQuency:STARt?
Response: 9000
MIN/MAX
MINimum and MAXimum denote the minimum and maximum
value.
UP/DOWN
UP, DOWN increases or decreases the numerical value by one
step. The step width can be specified for most parameters with a
separate command. Some parameters can only be changed in
fixed steps (e.g. SENSe:BWIDth UP).
R&S PR100
User Manual
INF
INFinity stands for +^. For queries the numerical value 9,9E37
is output.
NINF
Negative INFinity (NINF) stands for -^. For queries the
numerical value -9,9E37 is output. In a measured-value query,
this value is output if the measurement cannot be carried out
(e.g. due to a wrong device setting).
NAN
Not A Number (NAN) stands for results of calculations that are
not number. Possible causes are the division by zero, the
subtraction of infinity from infinity and simply missing values..
SCPI outputs the value 9,91E37 where NAN is meant. NAN is
only sent as a device response, it cannot be entered in a
command.
Boolean parameters
Boolean parameters represent two states. The ON state (logically true) is
represented by ON or a numerical value unequal to 0. The OFF state
(logically untrue) is represented by OFF or the numerical value 0. 0 or 1 is
provided in a query.
Example:
Setting command: SYST:COMM:SOCK:DHCP:STAT ON
Query:
SYST:COMM:SOCK:DHCP:STAT?
Response: 1
Text
Text parameters (character data) observe the syntactic rules for keywords, i.e.
they can be entered using the short or long form. Like any parameter, they
have to be separated from the header by a "white space". In the case of a
query, the short form of the text is provided.
Example:
Setting command: FORMat:BORDer SWAPped
Query:
FORMat:BORDer?
Response SWAP
Strings
Strings must always be entered in quotation marks (' or ").
Example:
PROGram:PRESet:DEFine “User Preset 1”
PROGram:PRESet:DEFine ‘User Preset 2’
Block Data
Block data (Definite Length Block) are a transmission format which is suitable
for the transmission of large amounts of data. A command using a block data
parameter has the following structure:
Example:
HEADer:HEADer #45168xxxxxxxx
R&S PR100
User Manual
ASCII character # introduces the data block. The next number indicates how
many of the following digits describe the length of the data block. In the
example the 4 following digits indicate the length to be 5168 bytes. The data
bytes follow; a single character for each byte. Data elements comprising more
than one byte are transmitted with the byte being the first that was specified
by SCPI command "FORMat:BORDer".
During the transmission of the data bytes all flow-control (e.g End-of-Line) that
is sent as an ASCII character is ignored until all bytes are transmitted. Note
that e.g. a VXI-11 connection also has flow-control that is not sent as ASCII
characters.
Expressions
Expressions must always be in parentheses.
Syntax Elements
Table 1 offers an overview of the syntax elements.
Table 1: Syntax Elements

Parentheses enclose an expression (channel lists).
9.2 Status Reporting
The status reporting system stores all the information on the present operating
state of a device and on errors that have occurred. This information is stored
in the status registers and in the error queue.
For each remote client of a device there is a separate status reporting system
that offers access to all registers of the error queue. The registers form a
hierarchical structure. The register “status byte” (STB) defined in IEEE 488.2
and its associated mask register “service request enable” (SRE) form the
uppermost level.
R&S PR100
User Manual
The STB receives information from the other registers and evaluates whether
an SRQ or IST message has to be generated: The IST flag ("Individual
STatus") and the “parallel poll enable” register (PRE) allocated to it are also
part of the status reporting system. The IST flag, like the SRQ, combines the
entire device status in a single bit. The PRE fulfils a function for the IST flag
as the SRE does for the service request.
For SCPI over TCP/IP, an SRQ is a text-response “&SRQ<CR><LF>”, where
<CR> is a carriage-return, and <LF> is a line-feed. A C-type string would read
as: “&SRQ\r\n”.
The message queue contains the messages the device sends back to the
controller. It is not part of the status reporting system but determines the value
of the “message available” (MAV) bit in STB and is thus shown in Section
9.2.2.2.
Structure of an SCPI status register
Each SCPI register consists of 5 sections each having a width of 16 bits (see
Figure 2). Bit 15 (the most significant bit) is set to zero for all sections. Thus
the contents of the register sections can be processed by the controller as
positive integers. The function of each section is explained below.
CONDition section
The CONDition section of a register reflects directly the state of the hardware.
This register section can only be read. Its contents are not changed during
reading. As an alternative, a bit in a CONDition register can also contain the
summary information of a further status register connected in front. In this
case, the bit is cleared only when reading out the root-cause of the bit:
another bit in another status register connected in front.
PTRansition section
The Positive-TRansition section acts as an edge detector. When a bit of the
CONDition section is changed from 0 to 1, the associated PTR bit decides
whether the EVENt bit is set to 1.
PTR bit = 1: the EVENt bit is set.
PTR bit = 0: the EVENt bit is not set.
This section can be written into and read from in any way. Its contents are not
changed during reading.

Figure 2: Status Register Model
NTRansition section
The Negative-TRansition section also acts as an edge detector. When a bit of
the CONDition section is changed from 1 to 0, the associated NTR bit decides
whether the EVENt bit is set to 1.
NTR-bit = 1: the EVENt bit is set.
NTR-bit = 0: the EVENt bit is not set.
This section can be written into and read from in any way. Its contents are not
changed during reading.
With these two edge register sections the user can define which state
transition of the condition section (none, 0 to 1, 1 to 0 or both) is stored in the
EVENt section.
EVENt section
The EVENt section indicates whether an event has occurred since the last
reading, it is the "memory" of the CONDition section. It only indicates events
passed on by the edge filters. The EVENt section is permanently updated by
the device. This part can only be read. During reading, its contents are set to
zero. This section is often regarded as the entire register.
ENABle section
The ENABle section determines whether the associated EVENt bit contributes
to the summary bit (see below). Each bit of the EVENt section is ANDed with
the associated ENABle bit (symbol '&'). The results of all logical operations of
this section are passed on to the summary bit via an OR operation (symbol
'1').
R&S PR100
User Manual
ENABle bit = 0: the associated EVENt bit does not contribute to the
summary bit
ENABle bit = 1: if the associated EVENT bit is "1", the summary bit is
set to "1" as well.
This section can be written into and read by the user in any way. Its contents
is not changed during reading.
Summary bit
As indicated above, the summary bit is obtained from the EVENt and ENABle
section for each register. The result is then entered into a bit of the CONDition
section of the higher-order register. The device automatically generates the
summary bit for each register. Thus an event, e.g. a PLL that has not locked,
can lead to a service request through all the hierarchy levels.
Note
The service request enable register SRE defined in IEEE 488.2 can be taken
as ENABle section of the STB if the STB is structured according to SCPI. By
analogy, the ESE can be taken as the ENABle section of the ESR.

Figure 3: Status Registers
9.2.1 Description of the status registers
9.2.1.1Status Byte (STB) and Service Request Enable Register
(SRE)
The STB is already defined in IEEE 488.2. It provides an overview of the
device status by collecting the pieces of information of the lower registers. It
can thus be compared with the CONDition section of an SCPI register and
R&S PR100
User Manual
assumes the highest level within the SCPI hierarchy. A special feature is that
bit 6 acts as the summary bit of the other bits of the status byte.
The STATUS BYTE is read out using the command "*STB?".
The STB implies the SRE. As to its function, it corresponds to the ENABle
section of the SCPI register. A bit in the SRE is assigned to each bit of the
STB. Bit 6 of the SRE is ignored. If a bit is set in the SRE and the associated
bit in the STB changes from 0 to 1, a Service Request (SRQ) is generated.
The SRE can be set using command "*SRE" and read using "*SRE?".
Table 2: Bit allocation of status byte
Bit
No.
Meaning
0
EXTended status register summary bit
The bit is set if an EVENt bit is set in the EXTended-status register
and if the corresponding ENABle bit is set to 1. The states of the
hardware functions and change bits are combined in the EXTendedstatus register.
TRACe status register summary bit
The bit is set if an EVENt bit is set in the TRACe-status register and if
the corresponding ENABle bit is set to 1. The states of the TRACes
MTRACE, ITRACE, SSTART and SSTOP are represented in the
TRACe-status register.
Error Queue not empty
The bit is set when the error queue contains an entry. If this bit is
enabled by the SRE, an entry into the empty error queue generates a
service request. Thus, an error can be recognized and specified in
greater detail by polling the error queue. The poll provides an
informative error message.
QUEStionable status register summary bit
The bit is set if an EVENt bit is set in the QUEStionable-status register
and the corresponding ENABle bit is set to 1. A set bit indicates a
questionable device status which can be specified in greater detail by
polling the QUEStionable-status register.
MAV bit (message available)
This bit is set when the message queue is not empty.
ESB bit
Summary bit of the EVENt status register. It is set if one of the bits in
the EVENt status register is set and is also enabled in the EVENt
status enable register. Setting of this bit implies a serious error which
can be specified in greater detail by polling the EVENt status register.
MSS bit (master status summary bit)
The bit is set if the device triggers a service request. This is the case if
one of the other bits of this register is set together with its mask bit in
the service request enable register SRE.

OPERation status register summary bit
The bit is set if an EVENt bit is set in the OPERation-status register
and the corresponding ENABle bit is set to 1. A set bit indicates that
the device is just performing an action. The type of action can be
determined by polling the OPERation-status register.
9.2.1.2IST flag and Parallel Poll Enable (PPE) register
Analogous to the SRQ message, the IST flag combines the entire status
information in a single bit. It can be queried by using command "*IST?".
The parallel poll enable register (PPE) determines which bits of the STB
contribute to the IST flag. The bits of the STB are ANDed with the
corresponding bits of the PPE. In contrast to SRE bit 6 is also used here. The
IST flag results from the ORing of all results. The PPE can be set using the
"*PRE" commands and read using the "*PRE?" command.
9.2.1.3Event Status Register (ESR) and Event Status Enable
(ESE) register
The ESR is already defined in IEEE 488.2. It can be compared with the
EVENt section of an SCPI register. The EVENt status register can be read out
using the "*ESR?" command.
The ESE is the associated ENABle section. It can be set using the "*ESE"
command and read using the "*ESE?" command.

Device-dependent error
This bit is set if a device-dependent error occurs. An error message
with a number between -300 and -399 or a positive error number
denoting the error in greater detail is entered into the error queue
(see Section 9.3).
Execution Error
This bit is set if a received command is syntactically correct but cannot
be performed for different reasons. An error message with a number
between -200 and -299 denoting the error in greater detail is entered
into the error queue (see Section 9.3).

9.2.1.4STATus:OPERation register
In the CONDition section, this register contains information about the type of
actions currently being executed by the device. In the EVENt section, it also
contains information about the type of actions having been xecuted since the
last reading. It can be read using the commands

With bits 0 to 2 and 7 to 9 and 12 to 14, the host can be informed via an SRQ
about parameter changes. Cyclical polling of the settings by the host is thus
stopped during manual operation or if the signal parameters are to be
indicated. In the CONDition section of the register, the change bits are set
after manual control or signal change and are reset by special query
commands. Changes done by front panel or by another remote client affect
the change bits equally.

9.2.2 Use of the Status Reporting System
In order to be able to effectively use the status reporting system, the
information contained there has to be transmitted to the host where it is further
processed. There are several methods which are described in the following
sub-sections.
9.2.2.1Service request, making use of the hierarchy structure
Under certain circumstances, the device can send a "service request" (SRQ)
to the host. As Section 0 shows, an SRQ is always initiated if one or several
of the bits 0, 1, 2, 3, 4, 5 or 7 of the status byte are set and enabled in the
SRE. Each of these bits combines the information of a further register, the
error queue or the output buffer. By setting the ENABle sections of the status
registers correspondingly, it can be achieved that any bits in any status
register initiate an SRQ. In order to use the service request, some bits should
R&S PR100
User Manual
be set to "1" in enable registers SRE and ESE. Only those bits need to be set
that represent the situations for which a service request must be received.
Examples (also see Section 0):
Use command "*OPC" to generate an SRQ
• Set bit 0 in the ESE (Operation Complete)
• Set bit 5 in the SRE
After completion of the settings, the device generates an SRQ. For SCPI over
TCP/IP, this is a text-response “&SRQ<CR><LF>”, where <CR> is a carriagereturn, and <LF> is a line-feed. A C-type string would read as: “&SRQ\r\n”.
Indication of a signal during a sweep by means of an SRQ at the host
• Set bit 7 in the SRE (summary bit of the STATus:OPERation register)
• Set bit 3 (SWEeping) in the STATus:OPERation:ENABle.
• Set bit 3 in the STATus:OPERation:NTRansition so that the change of
SWEeping-bit 3 from 0 to 1 is also recorded in the EVENt section.
• Set bit 0 in STATus:OPERation:SWEeping:ENABle
• Set bit 0 in STATus:OPERation:SWEeping:PTRansition so that the
change of hold-bit 0 from 0 to 1 is also recorded in the EVENt section.
The device generates an SRQ after a signal has been found.
Once an SRQ has been received, the contents of the status-byte register can
be polled. For SCPI over TCP/IP, polling is done by sending the string
“&POL”. The PR100 device then answers with the string
“&<value><CR><LF>”, where <value> is the decimal value of the contents of
the STB.
The SRQ is the only possibility for the device to become active on its own.
Each host program should set the device so that a service request is initiated
in case of malfunction. The program should react appropriately to the service
request.
9.2.2.2Query by means of commands
Each part of every status register can be read by means of queries. Only one
number is returned which represents the bit pattern of the register queried.
The format of the number can be set by the FORMat:SREGister command.
Queries are usually used after an SRQ in order to obtain more detailed
information on the cause of the SRQ.
9.2.2.3Error-queue query
Each error state in the device results in an entry in the error queue. The
entries of the error queue are detailed plain-text error messages which can be
queried by the command SYSTem:ERRor?. Each call of SYSTem:ERRor?
provides one entry from the error queue. If no error messages are stored
there anymore, the device responds with 0, "No error".
The error queue should be queried after every SRQ in the controller program
as the entries describe the cause of an error more precisely than the status
registers. Especially during the test phase of a controller program the error
queue should be queried regularly since faulty commands from the controller
to the device are recorded there as well.

9.3 Error Messages
The following list contains all error messages for errors occurring in the
instrument. The meaning of negative error codes is defined in SCPI (Standard
Commands for Programmable Instruments), positive error codes mark errors
specific for the instrument.
In the left column the table contains the error text which is entered in the
error/event queue. In the right column there is an explanation regarding the
respective error.
For some errors, a so-called device-dependent info is added to the error
message. It gives further information about the error source (eg. -222, "Data
out of range", frequency too high).

9.4 Commands Description
9.4.1 Notation
In the following sections, all commands implemented in the device are
described in detail. The notation corresponds to the SCPI standard.
Indentations
The different levels of the SCPI command hierarchy are represented in the
description by means of indentations to the right. The lower the level is, the
further is the indentation to the right. Please observe that the complete
notation of the command always includes the higher levels as well.
Example:
SENSe:FREQuency:STARt is indicated in the description as follows:
SENSe
first level
. :FREQuency
second level
. . :STARt
third level
Upper-/Lower Case
Upper/lower-case letters serve to mark the long or short form of the key words
of a command in the description (see next sections). The device itself does
not distinguish between upper- and lower-case letters.
Special Characters
| - Vertical Stroke
A selection of keywords with an identical effect exists for some commands.
These keywords are given in the same line and are separated by a vertical
stroke. Only one of these keywords has to be indicated in the header of the
command. The effect of the command is independent of the keywords being
indicated.
Example:
R&S PR100
User Manual
SENSe
. :BANDwidth|:BWIDth
The two following commands of identical meaning can be formed. They set
the frequency of the device to 123 MHz:
SENSe:BANDwidth 150E3
=
SENSe:BWIDth 150E3
A vertical stroke in indicating the parameters marks alternative possibilities in
the sense of "or". The effect of the command is different, depending on which
parameter is entered.
Example: Selection of parameter for command
SENSe:GCONTrol:MODE FIXed|MGC AUTO|AGC
If the parameter FIXed is selected, the gain is determined by the MGC
voltage. In case of AUTO the gain depends on the signal. The two
parameters MGC and AGC are synonymous for FIXed and AUTO.
[ ] – Square Brackets
Keywords in square brackets can be omitted in the command. The device also
accepts the full command. Parameters in square brackets can also be
optionally inserted into the command or can be omitted.
{ } – Curly Braces
Parameters in braces can be inserted in the command once or several times,
or be omitted altogether.
9.4.2 Common Commands
The common commands are taken from the IEEE 488.2 (IEC 625-2) standard.
A particular command has the same effect on different devices. The headers
of these commands consist of an asterisk "*" followed by three letters. Many
common commands concern the "status reporting system" in Section 9.

10 Instrument Behaviour
The behaviour of the Orion MR is defined by the following aspects:
• Error Situations
There are several types of error situations that apply to a number of,
otherwise unrelated, commands
• Ranging and Rouding
This applies to all commands that set a value. Ideally, the user supplies
a value that is within the instrument’s range and corresponds with its
resolution. When this ideal situation is not met, ranging and rounding
must be applied to get a value the instrument can handle.
R&S PR100
•
•
•
User Manual
Value Representation
This applies to all commands that return a value. This value must be
presented to the user with an adequate accuracy.
Default Values
Each parameter that can be set or queried via SCPI has a default value
after applying the *RST command.
Instrument States
The behaviour of a command may vary between instrument states
10.1 Error Situations
The common behaviour of the instrument in error situations is as shown in the
list below (unless other behaviour has been explicitly specified for a specific
command or query):
•
•
•
Do a command or query in an instrument state in which the
command/query is not supported
The error -221 “Settings conflict” is returned
Set a parameter to such a state that it conflicts with other parameters
The error -221 “Settings conflict” is returned. The device does not
adapt other parameters in order to try to resolve a settings conflict. The
new parameter setting is rejected and the device setup remains
unchanged.
Query a measurement result that is not available
SCPI outputs NAN instead of a value acc. to SCPI standard Section
7.2.1. Note that NAN is output as 9.91E37, as is also described in
[SCPI] and [Orion SCPI].
Differences with EB200/EM050 Devices:
• A similar error situation may produce a different error code and
message on the Orion MR and on the EB200/EM050.
10.2 Ranging and Rounding
Each parameter of the device that takes a value has a maximum and a
minimum. In addition, each parameter has a resolution. The approach for
setting a value for a parameter is as follows:
• if the supplied value is beyond its maximum or below its minimum,
return error -222 “Data out of range” without changing the parameter.
The device does not adapt other parameters in order to try to resolve a
data out of range situation. The new parameter setting is rejected and
the device setup remains unchanged.
• round the supplied value to the device’s resolution. For specific
parameters (e.g. bandwidth), Orion can choose to round up or down
instead of rounding towards the closest value.
• if the supplied value results in an error situation, return an error
appropriate for that situation without changing the parameter.
R&S PR100
User Manual
• accept the rounded value.
Differences with EB200/EM050 Devices:
• The EB200 operates as described above, but does rounding before the
range checking. That means that a value that is out of range, but within
the resolution of the minimum or maximum, is accepted.
10.3 Value Representation
When a value (from either a measurement or from a setting) is presented to
the user by means of a response to an SCPI query, it is presented with the
accuracy that is used by the instrument. Exceptions to this rule will be
documented.
10.4 Default Values
The device has only one set of default values: That means that both the user
interface and the remote interface (SCPI) use the same default values for
parameters. This is identical to the EB200/EM050 devices.
The EB200 and the Orion MR do not use the same set of default parameters
and their values are not the same either.
10.5 Instrument States
10.5.1
Introduction
In order to get a good overview of how the Orion MR reacts to SCPI
commands, one should study the various instrument states the device can
have. These states dictate if an SCPI command is rejected or allowed. When
a command is allowed, two situations can be distinguished:
• the command triggers a state transition and executes from there
• the command executes in the current state
This section describes the instrument states and shows the commands that
trigger state transitions. A full description of these commands is part of the
subsequent chapters. Each command is assigned to one or more states in
which it can execute.

This chapter describes the SCPI commands that are specific to the Orion MR
product. They are additional to the list in Chapter 4 of [Orion SCPI].
11.1 Common Commands
The commands listed in this section are taken from the IEEE 488.2 (IEC 6252) standard and are supported by all instruments. However each instrument
type may respond differently, e.g. the option query comannd returns all

INITiate
. :CONM
. . [:IMMediate]
The INITiate CONtinue Measurement is identical to the INITiate command
described in the previous section except for the fact that trace buffers are not
cleared and an active scan is not restarted. Using the CONTinue
Measurement form appends new measurement values to the current values
present in the trace buffers. Using this command when a scanner causes the
scanner to select the next frequency in frequency scan mode or the next
memory channel when the memory scanner is active.
Parameters:
None

Memory list subsystem
The commands listed in this section are only intended for testing the
associated function in the user interface. They are not to be used by the
remote user.
Although each memory location (0...1023) can be addressed directly, it is
sometimes convenient to run through all of them in a specific order (e.g. in
R&S PR100
User Manual
order of increasing frequency). To accomodate both an unordered and an
ordered accesss of the memory locations, the memory list is used.
The memory list has a number of items, one for each memory location. Each
item links to a certain memory location. This way, the order in the memory
locations can remain unchanged, while the list item allow to run through the
memories in another order. See below an example for ordering on increasing
frequency via the memory list:
...
item 55
->
25 (freq. 100000000)
item 56
->
6 (freq. 125000000)
item 57
->
2 (freq. 140000000)
item 58 ->
800 (freq. 160000000)
...
The memory scan (SENS:FREQ:MODE MSC) uses the memory list to run
through all memory locations. The commands below under the MEMory:LIST
subsystem control the order of the memory list.
MEMory
. :LIST
. . :CONTents? <index>
Query to which memory location a list item has been linked
Parameter:
<index>
integer number in the range [0,1023]
Result:
0...1023
Example:
MEMory:LIST:CONTents? 25 -> 60

Memory save subsystem
This subsystem contains all commands for automatically saving receiver
settings to memory locations.
MEMory
. :SAVE
. . :AUTO
. . . :STARt <mem_loc>
Sets first memory location that is used to save receiver settings when
automatic save is active. The last location is set with
MEM:SAVE:AUTO:STOP. A start location that is larger than the stop location
is rejected with error -221(“Settings conflict”).
This setting applies to scans with squelch on (see OUTP:SQU:STOR). When
the received signal is stronger than the squelch level during a memory scan or
a frequency scan, the receiver settings are saved into the first free auto-save
memory-location (see MEM:SAVE:AUTO:STAR and
R&S PR100
User Manual
MEM:SAVE:AUTO:STOP). This setting is ignored in case the squelch is off
(see OUTP:SQU:STAT).

:DATA? [<data_handle>]
Query of the most current measured values of active sensor functions.
Measurement values may not be available yet at the moment when this query
is issued, for example. immediately after a receiver setting have been
changed. If this is the case the query will block until the data will become
available. If MEASurement:MODE is CONTinuous this may take up to 200
ms, if PERiodic it may take up to the measurement time
(MEASurement:TIME).
The unit may actively report the end of measurement (MEASuring bit in
operation status register becomes inactive) via SRQ if the status register has
been configured accordingly (see also Section 9).
Remark:
For this command the keyword SENSe must not be omitted as DATA? can be
mixed up with the subsystem TRACe:DATA.
When the scan mode is PSCan, this command returns the error -221
(“Settings conflict”).
Parameters:
none
Output of the measured values of all active sensor functions.
<data_handle>
see the command SENS:FUNC:ON for the available
functions
Error:
If a requested function is not switched on, or if no functions are switched on,
error -221, "Settings Conflict" is generated.
Result:
The values for the various data-handles are output in the order as specified
under the SENS:FUNC:ON command. The output format (ASCii or block data)
is determined by the command FORMat:DATA. If the output format is block
data, the command FORMat:BORder defines whether the data is output in
big- or little-endian byte order.

Sense Memory Scan subsystem MSC
The MSCan system controls the memory-scan function of the device,
provided the memory scan has been activated by SENSe:FREQuency:MODE
MSCan. Each scan is started by INITiate[:IMMediate]. The memory locations
are placed in the MEMory subsystem and are set for query during the scan.
[SENSe]
. :MSCan
. . :CHANnel <mem_loc>|UP|DOWN|NEXT
Setting of current memory location. During the memory scan, this command is
not permitted and generates error -200 , “Execution error”
Parameters:

UP|DOWN the next or previous memory location
NEXT
the next free memory location is selected, starting from and
including the current location.
If the end of the memory list is reached without finding a free
location, the search continues

[SENSe]
. :MSCan
. . :CONTrol
. . . :[ON] <control_function> {,<control_function>}
Command for switch-on of the 'STOP:SIGNal' function. When this function is
off, the memory scan stops at each location with a signal for the dwell-time.
When this function is on, the dwell-time is controlled by the presence of a
signal stronger than the threshold level:
During a memory-scan, the receiver moves from one memory location to
another, loading the settings into the receiver. If a memory location has a
signal that is stronger than the threshold level, the receiver stays on that
memory location for a certain time, called dwell time. When the signal
disappears during that dwell time, the receiver stays on the same location for
a while, called hold time, to see if the signal re-appears. When either the holdtime or the dwell-time has elapsed, scanning continues.
If the signal does re-appear, the receiver continues the dwell time again (the
dwell-time never stopped), otherwise it moves to the next memory location.
This value is mapped onto the same variable as the frequency scan control
mechanism variable, meaning that a change affects both scan modes.
Parameters:
<control_function> is the following string:
“STOP:SIGNal”
switches the signal-controlled dwell time on
*RST state:
after *RST, all control mechanisms are on
Example:

. . :HOLD
. . . :TIME <numeric_value>|MINimum|MAXimum
Setting the hold time for a signal-controlled scan continuation. If the signal
disappears during the dwell time, the hold time is started. After completion of
the hold time, the scan is continued with the next frequency even if the dwell
time has not yet been completed. If the signal exceeds the squelch threshold
during the hold time, the hold time is reset and the end of the dwell time or the
renewed disappearance of the signal is awaited. The hold time is only used if
the control function "STOP:SIGNal" (see SENSe:MSCan:CONTrol) is
switched on.
Setting the time to 0 (zero) has the same effect as switching off the control
function with SENS:MSC:CONT:OFF “STOP:SIGN”.
This value is mapped onto the same variable as the frequency scan hold time
variable, meaning that a change affects both scan modes.

11.17 TRACe|DATA subsystem
Instead of the command word TRACe, DATA can also be used. Traces are
used for summarizing data. Several predefined traces are available. Each one
is described below.
Result Traces: MTRACE, ITRACE
For the results, two predefined traces (MTRACE = Measurement Trace and
ITRACE = Information Trace) are available. They cannot be deleted.
MTRACE receives its data from the SENSe:FUNCtion block. All sensor
functions switched on deliver their measured values to the MTRACE where
they are stored. ITRACE receives its data from the SENSe:FREQuency block.
In addition to the current receiver frequency the corresponding channel
number is also stored. The start command to initiate measurement
(INITiate[:IMMediate]) clears the MTRACE (or ITRACE) data set.
Via the control instruction(TRAC:FEED:CONT), a condition can be defined
that selects the data to be written into the MTRACE or ITRACE. If the control
conditions of the two traces are identical, each TRACE value has a
corresponding information value in the ITRACE. When the maximum data set
length is attained, MTRACE and ITRACE are closed down. Any subsequent
data are thus lost.
In the status reporting system the state of this traces is available in the status
bits (see Section 9.2.1.6).
IF Panorama Trace: IFPAN
The command TRACe:FEED:CONTrol IFPAN, ALWays starts loading of the
IFPAN Trace. The command DISPlay:MENU IFPAN starts the IF panorama,
and the data levels are output. The spectrum length depends on the
bandwidth chosen. The current number of pixels can be queried by the
command TRACe:POINts? IFPAN
In the status reporting system the state of this traces is available in the status
bits (see Section 9.2.1.6).
R&S PR100
User Manual
Suppress Traces: SSTART, SSTOP
Suppress lists are stored as two predefined traces, SSTART (= Suppress
START) and SSTOP (=Suppress STOP). The suppress list has 100 elements
with each element consisting of two frequencies. The frequency pair specifies
a frequency range which is suppressed during the scan. It is irrelevant that the
1st frequency is lower than the 2nd frequency. The sequence in the list is
irrelevant, too. Gaps are specified by the frequency pair 0.0. If one frequency
of the frequency pair is 0, the other frequency of the pair is seen as a single
frequency.
Examples:
1st 2nd Frequency Description
Frequency
118000000
136000000 Suppression of range 118 to 136 MHz
98550000
98450000 Suppression of range 98,450 to 98,550
MHz
0
0 Empty frequency pair (irrelevant)
118375000
0 Suppress single frequency 118,375 MHz
0
123400000 Suppress single frequency 123,400 MHz
127675000
127675000 Suppress single frequency 127,675 MHz
When retrieving the above list via the two queries “TRAC:DATA? SSTART”
and “TRAC:DATA? SSTOP”, the list is slightly corrected: All single
frequencies get the same frequency value in the SSTART and the SSTOP list.
Clearing the suppress lists must always include both commands (TRAC
SSTART, 0; TRAC SSTOP, 0).

11.18 TRACe|DATA:UDP subsystem
This sub-system controls what trace data are sent over UDP to a remote
client. Each destination to which UDP data can be sent is called a UDPaddress (which is equivalent to an IP address and port number). This subsystem keeps a list of all UDP-addresses that are used. The first item in this
list is the default UDP-address, which is always present, and is retained after
a power down and up.
For a description of how trace data are sent over UDP see Chapter 12.
d
TRACe|DATA
. :UDP? [<numeric_value>|MINimum|MAXimum|DEFault]
Query of available UDP-addresses and flags and tags that are set by the user.
See Table 19 for tags and Table 20 for flags in Section 12.1.. Note that there
are no predefined UDP-addresses. Each one must be entered by the user via
a TRAC:UDP[:DEF]:TAG:ON and TRAC:UDP[:DEF]:FLAG:ON command.
Parameters:
none
lists all UDP addresses as in TRACe:UDP?
<numeric_value>, each on a new line
<numeric_value> integer in the range [MIN, MAX]
MINimum
minimum index in the list of UDP-addresses (always 0)
MAXimum
maximum index in the list of UDP-addresses
DEFault
returns the index of the default UDP-address (always 0)
Result:
DEF|<numeric_value> [<ip-address>, <ip-port> {, tag } {, flag } ]
Example:
TRACe:UDP? MAX -> 3
TRACe:UDP? DEF -> 0
TRACe:UDP? 0 -> DEF
This means that the default UDP address has not yet been defined.
TRACe:UDP? 0 -> DEF “123.456.789.012”, 5555, FSC, MSC, “FSTRength”
This means that field strength data is output in F-scan and M-scan data
packets to port 5555 on IP address “123.456.789.012”.
TRACe:UDP? 3 -> 003 “012.123.456.789”, 4444, FSC, MSC, “VOLTage:AC”
This means that received-level data is output in F-scan and M-scan
data packets to port 4444 on IP address “012.123.456.789”.

12 UDP Data Streams
This chapter describes the data streams that can be output by the Orion MR.
All data streams have a similar (general) structure, which is described in
Section 12.1. After that, each data stream is described in a separate section.
12.1 Stream Packet Structure
Each stream consists of a number of UDP packets, and each packet has a
similar structure that is shown in Table 18. The first (light grey) part is the
common header which is the same for all stream types. Its <attribute tag>
determines the stream type, and its <trace selector flags> determines what
data are included.
The <optional header> and the <trace data> are different for each stream
type. Each stream type is further described in a separate section.
The <trace selector flags> shown in Table 20 define the data items that are
included in a data stream. The Orion MR does not support all data items that
the ESMB version of its predecessor, the EB200, supported. The following
items are not supported: AM, AM_POS, AM_NEG, FM, FM_POS, FM_NEG,
PM, and BANDWIDTH.
R&S PR100
User Manual
The data items as defined by the <trace selector flags> are not included
automatically, but must be selected through an SCPI command (see
TRACe:UDP:FLAGs). Not all items are possible with every data stream type.
For every data stream type, the items that are allowed are mentioned
explicitly.

The data fields in the common header are always sent in Big Endian order (=
most significant byte first).
For <optional header> and <trace data> the order is determined by the
selector flag SWAP (see Table 20): if SWAP is not set the order is Big Endian,
if set the order is Little Endian.
The selector flags OFFSET and FSTRENGTH shown in Table 20, only have
an effect if the corresponding measurement functions are switched on:
OFFSET requires SENS:FUNC:ON “FREQuency:OFFSet”
FSTRENGTH requires SENS:FUNC:ON “FSTRength”
Note that LEVEL does not require the corresponding measurement function.
The selector flag CHANnel only contains the channel number when the
frequency mode is MSCan or FSCAN. Otherwise, it contains the value zero.
Table 20: Settings for <trace selector flags>. The “C Data Type” column
is the data type of the data that are included by setting the associated
flag. It is not the data type of the flag itself.

Note:
The Selector flag “FREQuency:LOW:RX” and “FREQuency:RX” are the same.
The “FREQuency:RX” flag is compatible with the older receivers and supports
frequencies < 4 GHz.
Since the PR100 frequency range is > 4 GHz a new flag
FREQuency:HIGH:RX is introduced.
Backwards compatibility is realized by adding the higher 32 bits of a frequency
at the end of the optional header.
Empty packets (also those with an optional header but without data) are not
transmitted.
For packets that contain scan data (for FSCan, MSCan, and PSCan), the end
of a sweep (scan) is marked: The last item in a scan is always followed by an
end-marker. This end-marker is another item with unrealistic values:

Note that the end-marker is counted in the header field <trace number of
items>. E.g.: An FSCan from 100 MHz to 110 MHz with a 1 MHz step width
outputs 12 items: 11 measured items and 1 end-marker.
12.2 Audio
The audio stream is only active if SYST:AUD:REM:MODE has been set to
anything else but 0 (zero). It is further determined by two parameters:
• Audio mode: determines the data-rate and the format of the audio
samples
• Audio demodulation: determines the demodulation used to obtain the
audio samples, e.g. AM or FM
The applicable selector flags (see Table 20) are “OPTIONAL_HEADER” and
“SWAP”.
The header field <trace number of items> is the number of frames (see Table
25) in a packet.

12.6 IFPan
The IFPan stream contains the level information for all frequencies of an IF
panorama (not just the visible ones). That way, a program on a remote client
can display the panorama view itself in its own way. The number of
frequencies in an IFPan packet varies with the screen resolution.
The applicable selector flags (see Table 20) are “LEVEL”, “SWAP” and
“OPTIONAL_HEADER”.
Data are output when SENS:FREQ:MODE is CW. Each UDP packet contains
exactly one IF panorama.

12.7 IF
The IF stream contains source IQ data. Although the Audio stream can also
contain data in IQ form, it is not the same as this stream. This stream is the
source for the audio demodulation: The Audio IQ is obtained by processing
this stream. For the IF stream, the data rate can be very high: 640
kSamples/second (Req. SFD0248). It has 2 channels and 16 bit per sample.
At the maximum sample rate of 640k per second, the total data-rate is 2.56
MByte/s.
The only applicable selector flag is “OPTIONAL_HEADER”. All other flags
have no influence on the format of the IF stream. Data is always sent with the
SWAP flag set, independent of whether the SWAP flag has been configured
for this stream or not.
Data are output when no PSCAN/FSCAN/MSCAN is running, and additionally
also during the HOLD state in a running FSCAN/MSCAN.

12.8 PSCAN
A PSCAN in consists of several FFT measurements in a row. Each FFT
consists of x samples, where x depends on the “RF Panorama Scan
Resolution BW. Max x = 3199 and Min x = 99 samples, with 16 bit per sample.
The applicable selector flags (see Table 20) are “LEVEL”, “FREQ_LOW”,
“FREQ_HIGH”, “SWAP” and “OPTIONAL_HEADER”.
Data are output when PSCAN is running. Note that each packet contains one
single FFT. The Scan contains several FFT’s

To indicate the end of the PSCAN, a unique “end marker” sample for each
trace is inserted into the stream. The marker sample value depends on the
trace and is specified in Table 21.
Note1:
Analyzer 2000 uses the trace selector flag LEVEL, FREQ_LOW and
FREQ_HIGH to support frequencies > 4 GHz. Analyzer 2000 V5.05 + patch is
required. The patch = RSRxDrv.dll date 9-oct-2007, size 92KByte
Note2:
Analyzer 2000 supports the PSCAN stream RUN+ only.

The start and stop frequency stored in the option header are the start and stop
frequency the user has configured for PSCAN. The first sample of the PSCAN
stream will be the level at the start frequency. Since it is possible to configure
a stop frequency which is not a multiple of the PSCAN RBW, the last sample
is not measured at the PSCAN stop frequency. The PR100 will round off the
PSCAN nrOfSamples to + 1 if the span is not a multiple of the PSCAN RBW.
For the PR100 PSCAN stream client knows the frequency of a level by:
Assuming the scan direction is RUN(+)
1) Use the trace selector flag FREQ_LOW and FREQ_HIGH.
2) If the trace selector flag FREQ_LOW and FREQ_HIGH are not used
by:
f (level n) = f ( start ) + n RBW
where:
n = PSCAN sample number, starting from 0 at the PSCAN start
frequency.
f (start ) = PSCAN start frequency,
RBW = “RF Panorama Scan Resolution BW”

Figure 5 shows the payload of a PSCAN UDP package where the trace
selector flags “LEVEL”, “FREQ_LOW”, “FREQ_HIGH”, and
“OPTIONAL_HEADER” are set.
A PSCAN cycle is a single scan from start till the stop frequency.
The last sample of a cycle will be the “end marker” value.
A single PSCAN cycle consist of 1 or more PSCAN UDP packges.
