Basic Safety Instructions

Electrical safety

If the information on electrical safety is not observed either at all to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power

use of the product may have to be changed accordingly.

f

2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with an earthing contact and protective earth connection.

3. Intentionally breaking the protective earth connection either in the feed line or in the product itself is
not permitted. Doing so can result in the danger of an electric shock from the product. If extension
cords or connector strips are implemented, they must be checked on a regular basis to ensure that
they are safe to use.

4. If the product does not have a power switch for disconnection from the AC supply network, the plug of
the connecting cable is regarded as the disconnecting device. In such cases, always ensure that the
power plug is easily reachable and accessible at all times (corresponding to the length of connecting
cable, approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from
the AC supply network. If products without power switches are integrated into racks or systems, a
disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cable on a regular basis to
ensure that it is in proper operating condition. By taking appropriate safety measures and carefully
laying the power cable, you can ensure that the cable will not be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

6. The product may be operated only from TN/TT supply networks fused with max. 16 A (higher fuse
only after consulting with the Rohde & Schwarz group of companies).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket. Otherwise, sparks that result in fire and/or injuries may occur.

8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.

9. For measurements in circuits with voltages V

> 30 V, suitable measures (e.g. appropriate

rms

measuring equipment, fusing, current limiting, electrical separation, insulation) should be taken to
avoid any hazards.

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply
in each case.

11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.

12. If a product is to be permanently installed, the connection between the PE terminal on site and the
product's PE conductor must be made first before any other connection is made. The product may be
installed and connected only by a licensed electrician.

13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fused in such a way that anyone who has access to the product, as
well as the product itself, is adequately protected from injury or damage.

1171.0000.42-05.00 Page 3

Basic Safety Instructions

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

6. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and

1

operating positions", item 1. Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

2. Before you move or transport the product, read and observe the section titled "Transport".

3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.

4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal", item 1.

5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.

6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.

7. If a laser product (e.g. a CD/DVD drive) is integrated into a Rohde & Schwarz product, absolutely no
other settings or functions may be used as described in the product documentation. The objective is to
prevent personal injury (e.g. due to laser beams).

1171.0000.42-05.00 Page 4

Basic Safety Instructions

Repair and service

1. The product may be opened only by authorized, specially trained personnel. Before any work is

R&S®EM100 Functioning of the R&S®EM100

5 Functioning of the R&S®EM100

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 pad in the case of
high signal levels. The preselection as well as the attenuator pad 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®EM100 for further external processing.

Fig. 5-1: Block diagram, frontend

Digital signal processing

Following A/D conversion of the received signal, the signal path splits: The IF spectrum is computed
via a digital downconverter (DDC), a digital bandpass filter and the FFT block. The user can set the
bandwidth of the bandpass filter in a range from 1 kHz to 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. The second DDC and bandpass filter are used
to prepare the signal for level measurement or demodulation. 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. Next, the
measured level is output via the display or 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) representing the digitized signal is output
directly following the AGC/MGC block via the LAN interface.

User Manual R&S® EM100 - 31 EN 22

R&S®EM100 Functioning of the R&S®EM100

The results that are obtained are available in digital format and can be output as required via the LAN
interface. Digital audio data are reconverted to analog signals for output via the loudspeaker.

High receiver sensitivity, high signal resolution

The R&S®EM100 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 1 kHz yields maximum sensitivity.
The IF spectrum is digitally calculated by means of a fast Fourier transform (FFT). Usage of FFTs in
the IF stage has a significant benefit: Significantly more sensitive and higher-resolution reception
compared to conventional analog receivers with the same spectral bandwidth.

IF spectrum

For example, if the setting B

IF spectrum

= 10 kHz is chosen for sensitive signal reception, the following
steps will occur schematically in the FFT computation of the IF spectrum: Due to the finite edge
steepness of the IF filter, the sampling rate f
bandwidth B

IF spectrum

. The quotient of the sampling rate and the IF bandwidth is thus a value > 1 and is

must be greater than the selected IF spectrum

S

a measure of the edge steepness of the IF filter.

This relationship is expressed by the following two formulas:

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

F spectrum

I

wide, a sampling rate of f

= 10 kHz, this constant is equal to 1.28. In order to display an IF spectrum that is 10 kHz

= 12.8 kHz is thus required. The R&S®EM100 uses a standard FFT length

S

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 BW

of the frequency slices is

bin

obtained as follows:

BW

S

===

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 floor
(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 = –174 dBm + NF + 10 · log(BW

bin

/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. BW

) than would be expected for the wide display range of 10 kHz.

bin

Another advantage of the high spectral resolution used in the FFT calculation is that signals located
close together (e.g. f

, f2, f3) can be captured and represented in the IF spectrum as discrete signals

(see figure "Signal display in IF spectrum"). If, comparable to the operation of an analog receiver, a
resolution bandwidth equal to

a sum signal f
discrete signals f

would be displayed instead of the three

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"). Analogous to 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 the start and stop frequency, the R&S®EM100
automatically determines the required FFT length and the width of the frequency windows 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").

In the panorama scan mode, the resolution bandwidth of 100 kHz yields the maximum scan speed,
while the resolution bandwidth of 125 Hz yields maximum sensitivity. The resolution bandwidth (bin
width) for the panorama scan (selectable between 125 Hz and 100 kHz) therefore corresponds to the
resolution bandwidth (BWbin) used in the DANL calculation for the IF spectrum (see DANL formula
under "IF spectrum" above), and can thus be used for calculating the DANL for the panorama scan.
Moreover, the user selects the resolution bandwidth to obtain the desired frequency resolution (see
figure "Bin width and channel spacing").

connection can be used to input all of the SCPI commands and observe the responses. UDP streams
cannot be monitored in this manner.

It is assumed here that the IP address and subnet mask are known, or DHCP is activated and the
hostname is known.
See section "Setting the TCP parameters" (p. 37) for a description of how to set these parameters in
case they are not known.

R Connect the LAN cable to the PC and the EM100 (direct connection), or connect the EM100 to the

office network (network connection). The EM100 will automatically detect crossed and uncrossed
LAN cables.

R In case of a direct connection, set the IP addresses and subnet masks for the EM100 and PC so

that a connection can be established.

R In case of a network connection, set the EM100 to DHCP and configure the DHCP server as

required, or (without DHCP) set the IP addresses and subnet masks like for a direct connection.

User Manual R&S® EM100 - 31 EN 35

R&S®EM100 Initial Operation

R Open a DOS window and ping the EM100 as follows:

ping –a 172.17.75.1

The parameter –a returns the hostname of EM100 .

R If the connection is working, open a hyperterminal on the PC as follows:

Start-Program s-Accessories-Communication-Hyperterminal

Fig. 6-2: Hyperterminal connection setup

R In Hyperterminal, enable transmission of line ends and local echo as follows:

File – Properties – Settings – ASCII Configuration

R&S®EM100 Initial Operation

Fig. 6-3: Hyperterminal configuration

R In Hyperterminal, enter the SCPI command

*IDN? (+Return)

and the receiver should respond with
"Rohde&Schwarz", instrument type, serial number, firmware version.

Note: You might need to enter *IDN? several times before the receiver responds.

Fig. 6-4: Hyperterminal SCPI command

R Instead of Hyperterminal, you can also use a DOS window and open a telnet connection to the

receiver as follows:
telnet –t vt100 172.17.75.1 5555

Setting the TCP parameters

Method 1

Method 1 always works but requires an additional cable.

The following equipment is needed to set the IP address, subnet mask, port or DHCP setting:

 A special serial cable (R&S part number 4070.4481.00) in order to connect a COM port on a

PC to the EM100. This cable converts the levels from RS232 levels to low-level TTL.

 A PC or laptop with a COM port (D-Sub, 9 pins)
 A terminal program on the PC, e.g. Hyperterminal; see section "Setting up a connection" (p.

35)

Notes:

1) PCs without a COM port can be connected via a USB-to-RS232 cable + R&S cable, assuming
the terminal program can be operated with COM via USB.

User Manual R&S® EM100 - 31 EN 37

R&S®EM100 Initial Operation

2) A TCP cable can remain connected while setting the TCP parameters, but it cannot be
addressed since a TCP stack is not yet available during this time.

R Launch Hyperterminal
R In Hyperterminal, configure the RS232 connection as follows:

Fig. 5: RS232 settings for the AUX connection

R Switch off the R&S®EM100
R Connect the R&S cable via AUX2 to the R&S®EM100
R Make Hyperterminal the active window by clicking on it

(top bar blue, not gray)

R Repeatedly press the spacebar on the PC and switch on the R&S®EM100
R The following screen should appear in Hyperterminal:

User Manual R&S® EM100 - 31 EN 38

R&S®EM100 Initial Operation

Fig. 6: Terminal with network settings

R Modify the IP address, subnet mask, port and DHCP as required
R Start the EM100 with S
R It can also be started with F, but this will delete all of the user settings.

Method 2

Method 2 presumes that the receiver can be addressed via TCP (i.e. the IP address, etc. are known).
An additional cable is not required.

R Set up a telnet connection to the receiver; see section "Setting up a connection" (p. 35).

R Enter the commands for the required changes in a single line, e.g.:

"127.10.290.11"; :SYST:COMM:LAN:SUBM "255.0.0.0"

SYST:COMM:SOCK:ADDR

Note: The reason for entering the commands in a single line is that command lines (unlike queries) are
executed as a whole; all commands in the line are either executed jointly or rejected.

Command lines for TCP modification are also executed immediately. If each TCP command is sent in
a separate line, there is the risk that the user will be blocked out of the TCP connection if the receiver
becomes inaccessible after executing the first line.

R After execution of the TCP modification, the existing TCP connection terminates because the

receiver is now accessible via the new address.

R To test this, set up a telnet connection using the new address.

Firmware update

n order to be able to use all of the features of the R&S®EM100, it is recommended to update the

I
instrument to the latest firmware version.

The latest firmware can be downloaded from the R&S
terms EM100 firmware).

6.1.2 Preparations for updating the firmware

Interrupt any running scans

A currently running scan will significantly slow down the process of downloading the firmware files to
the SD card. Accordingly, you should interrupt it beforehand using the SCPI command ABORT or
*RST (or by switching the instrument off and back on again).

Exchange and format SD card if necessary

®

website (www.rohde-schwarz.com, search

The high recording speeds of the "Internal Recording" option necessitate the use of a high-quality,
class 6 SD card with a write speed of at least 133x / 20MB/s. A suitable card (4 GB, class 6) is
available from Rohde & Schwarz under part number 4070.4475.00.

SD cards with a size up to 32 GB can be used in the R&S®EM100.

For performance-related reasons, the card should be formatted using the SCPI command

MMEMory:INIT

(p.143).

User Manual R&S® EM100 - 31 EN 40

R&S®EM100 Initial Operation

6.1.3 Firmware Update with the Firmware Upgrade Tool

Starting with version 1.22, the firmware is supplied in the form of individual files for the SD card (see
above) as well as an update program. The update program works well if the SD card or the whole

eceiver is inaccessible.

r

The update program makes it possible to update the firmware via LAN without direct access to the SD
card. This is especially beneficial with the R&S®EM100 since its SD card can only be accessed by
opening the enclosure.

R Prior to the update

 Make sure that an SD card is inserted into the EM100. Approx. 30 MB of storage space must

be free on this card.

 Set up and test a LAN connection to the EM100; see section "Setting up a connection" (p. 35).

R To perform the update, launch the update program RS_PR_MR_<identification>.exe,

e.g. RS_PR_MR_V2_10.exe

User Manual R&S® EM100 - 31 EN 41

R&S®EM100 Initial Operation

Follow the instructions that appear on the screen.

Upon completion of the update, the following message will appear on the PC:

Notes:

The update program will not start if firmware version 1.21 (or earlier) is installed on the EM100.

Options

Existing options will be retained by the firmware update.

R Note: In case of a firmware update from versions 1.04 or 1.12 to a newer version, all of the option

codes must be entered initially.

For a description of how to enable new options which might be present for the first time in the current
firmware, see section “” (p. 43).

6.1.4 Firmware Update with the SD Card

This method works well only if the SD card is directly accessible. It is not recommended for the
R&S®EM100 since the R&S®EM100’s enclosure must be opened to access the SD card.

The firmware to be installed must first be copied to an SD card (e.g. R&S HA-Z231, order number

1309.6217.00).

The following files must be copied to the SD card:

The version numbers of the individual files (e.g. V2_00) are dependent on the current firmware
version.

User Manual R&S® EM100 - 31 EN 42

R&S®EM100 Initial Operation

Note!

Only one file of each type may be saved in the root directory of
the SD card. The update procedure will be interrupted if two
different versions of a given file type are found.

R Switch off the instrument.
R Insert the SD card into the SD card slot on the right side.
R Start the update using the SCPI command SYSTem:FIRMware:UPDate
R Wait 5 minutes, then read out the new firmware version using the following SCPI command:

*IDN?

Caution!

THE R&S®EM100
MUST NOT BE SWITCHED OFF DURING THE FIRMWARE
UPDATE!

R&S®EM100 Troubleshooting

7 Troubleshooting

ymptom: IP address changes unexpectedly.

S

ossible cause: DHCP was activated / deactivated. When DHCP is activated, the receiver obtains a

P
new IP address from the DHCP server. When DHCP is deactivated, the old static address is
reenabled.

Action: Set the desired DHCP status.

Side effects of action: None

Symptom : High load in entire network.

Possible cause: UDP stream in the EM100 was activated but the UDP sink (PC) cannot (or can no
longer) be reached. As a result, the UDP packets are broadcast via switches and routers in the entire
network, resulting in a high load.

Action: Disable the UDP stream or reenable the UDP sink.

Side effects of action: None

Symptom : Poor recording quality, missing data sets

Possible cause: SD card too slow.
Incorrect type, fragmented or not formatted in the EM100.

Action: Make sure that a class 6 SD card that handles 20 MB/s is used.
Format the card in the EM100.

Side effects of action: Formatting erases the data on the card.

All of the available remote-control commands for the R&S®EM100 (SCPI commands) are described in
detail hereafter in this manual.

R&S®EM100 SCPI Interface

8 SCPI Interface

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 EM100
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 EM100 is defined with the following rules:

1. If an EB200 SCPI command relates to functionality that is not supported by the EM100, 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 EM100.

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 EM100 also offers the data in another format that can be sent via the
UDP/IP protocol .

R&S®EM100 SCPI Commands

9 SCPI Commands

SCPI Introduction

SCPI (Standard Commands for Programmable Instruments) describes a standard command set for

rogramming devices, irrespective of the type of device or manufacturer. The goal of the SCPI

p
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 9-1 (S. 63) illustrates this tree structure
using a section of command system SYSTEM. The other examples regarding syntax and structure of
the commands are derived from the command system SENSE, which operates the sensor functions of
the devices.

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 consist of several keywords. Queries are formed by directly appending a
question mark to the header.

9.1.1Common Command Structure

Common commands consist of a header preceded by an asterisk "*" and one or several parameters, if

ny.

a

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.

9.1.2Device-Specific Command Structure

Hierarchy

Device-specific commands are of hierarchical structure (see Figure 9-1 (S. 63)). Commands of the
highest level (root level) consist of only one keyword. This keyword denotes a complete command
system.

Figure 9-1: Tree-Structure example of command system " 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:

User Manual R&S® EM100 - 31 EN 63

R&S®EM100 SCPI Commands

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.

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:

User Manual R&S® EM100 - 31 EN 64

R&S®EM100 SCPI Commands

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.

9.1.3Structure 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

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 9-1 (S. 63)). 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

9.1.4Responses 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 66).

Example: FORMat:BORDer?

Response: SWAP

9.1.5Parameters

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 11 (p.93)).

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:

R For frequencies GHz, MHz or MAHz, kHz and Hz, default unit is Hz
R For times s, ms, us, ns; default unit is s
R For levels dBcV; default unit is dBcV

User Manual R&S® EM100 - 31 EN 66

R&S®EM100 SCPI Commands

R 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

Table 9-2: Special numerical values

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).

INF INFinity stands for +

output.

NINF Negative INFinity (NINF) stands for - d. 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.

d. For queries the numerical value 9,9E37 is

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:

User Manual R&S® EM100 - 31 EN 67

R&S®EM100 SCPI Commands

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

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 flow­control that is not sent as ASCII characters.

Expressions

Expression must always be in parentheses.

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 (up to 5 cients are possible) 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.

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 carriage­return, 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 9.1.8.2.

9.1.6Structure of an SCPI Status Register

Each SCPI register consists of 5 sections each having a width of 16 bits (see Figure 9-2 (p. 70) ). 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.

User Manual R&S® EM100 - 31 EN 69

R&S®EM100 SCPI Commands

Figure 9-2: Status Register Model

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.

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

User Manual R&S® EM100 - 31 EN 70

R&S®EM100 SCPI Commands

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').

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 9-3: Status Registers

9.1.7Description of the Status Registers

9.1.7.1 Status 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 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 9-4: 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
EXTended-status register.

1 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.

2 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.

3 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.

4 MAV bit (message available)

This bit is set when the message queue is not empty.

5 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.

6 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.

7 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.

User Manual R&S® EM100 - 31 EN 73

R&S®EM100 SCPI Commands

9.1.7.2 IST 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.

9.1.7.3 Event 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.

Table 9-5: Bit allocation of event status register

Bit No. Meaning

0 Operation Complete

On receipt of the command *OPC, this bit is set exactly when all previous commands have been
executed.

2 Query Error

This bit is set if a query is faulty and hence cannot be executed.

3 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 “Error Messages” (p. 81)).

4 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 “Error Messages” (p. 81)).

5 Command Error

This bit is set if an undefined and syntactically incorrect command is received. An error message
with a number between -100 and -199 denoting the error in greater detail is entered into the
error queue (see section “Error Messages” (p. 81)).

7 Power On (supply voltage on)

This bit is set when the device is switched on.

9.1.7.4 STATus: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 executed since the last reading. It can be read using the commands

"STATus:OPERation:CONDition?" or
"STATus:OPERation[:EVENt]?".

either set to normal receive mode (Fixed Frequency Mode FFM) or to one of several scan modes
(FSCAN, MSCAN, PSCAN).

The status is determined by using the command SENSe:FREQuency:MODE. The CW|FIXed status is

This bit is set when the IF section is overdriven by an excessively high input signal. The result of a level measurement
is then suspect.

9.1.8Use 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.

9.1.8.1 Service Request, making use of the hierarchy structure

Under certain circumstances, the device can send a "service request" (SRQ) to the host. As Section

9.1.6 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 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 9.1.6):

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 carriage-return,
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.

User Manual R&S® EM100 - 31 EN 79

R&S®EM100 SCPI Commands

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 R&S EM100 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.

9.1.8.2 Query 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.

9.1.8.3 Error-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.

9.1.9Resetting Values of the Status Reporting System

Table 9-12 comprises the different commands and events causing the status reporting system to be

reset. None of the commands, except for *RST, influences the functional device settings. In particular,
DCL does not change the device settings.

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).

Commands Description

9.1.10Notation

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:

SENSe
. :BANDwidth|:BWIDth

The two following commands of identical meaning can be formed. They set the bandwidth of the
device to 150 kHz:

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.

User Manual R&S® EM100 - 31 EN 84

R&S®EM100 SCPI Commands

[ ] 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

mitted.

o

{ } Curly Braces

Parameters in braces can be inserted in the command once or several times, or be omitted altogether.

9.1.11Unprotected commands

Most of the SCPI commands described in this chapter are protected, meaning that they can only be
used if the Remote Control option has been installed (see SYSTem:SECurity:OPTion and *OPT?
commands).

Without this option a protected command will be refused with error -203 “Command protected”.

The following commands are unprotected (so they are always accepted):

User Manual R&S® EM100 - 31 EN 88

R&S®EM100 Instrument Behaviour

10 Instrument Behaviour

The behaviour of the R&S EM100 is defined by the following aspects:

Error Situations

R

There are several types of error situations that apply to a number of, otherwise unrelated,
commands.

R Ranging and Rounding

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 Value Representation

This applies to all commands that return a value. This value must be presented to the user with an
adequate accuracy.

R Default Values

Each parameter that can be set or queried via SCPI has a default value after applying the *RST
command.

R Instrument States

The behaviour of a command may vary between instrument states.

Error Situations

The common behaviour of the instrument in error situations is as listed below (unless other behaviour
has been explicitly specified for a specific command or query):

R Do a command or query in an instrument state in which the command/query is not supported

The error -221 “Settings conflict” is returned

R 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.

R 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].

Differences with EB200/EM050 Devices:

R A similar error situation may produce a different error code and message on the R&S EM100 and

on the EB200/EM050.

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:

User Manual R&S® EM100 - 31 EN 89

R&S®EM100 Instrument Behaviour

R 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.

R round the supplied value to the device’s resolution. For specific parameters (e.g. bandwidth), R&S

EM100 can choose to round up or down instead of rounding towards the closest value.

R if the supplied value results in an error situation, return an error appropriate for that situation

without changing the parameter.

R accept the rounded value.

Differences to EB200/EM050 devices:

R The EB200 operates as described above, but does rounding before the range checking. That

means that a value is accepted if it is out of range, but within the resolution of the minimum or
maximum.

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.

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 R&S EM100 do not use the same set of default parameters and their values are
not the same either.

Instrument States

10.1.1Introduction

In order to get a good overview of how the R&S EM100 reacts to SCPI commands, one should study
the various instrument states the device can have. If an SCPI command is disallowed or allowed
depends on the state the instrument is in. When a command is allowed, two situations can be
distinguished:

R the command triggers a state transition and executes from there
R 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 sections. Each command is assigned to
one or more states in which it can execute.

10.1.2Receiver States

CALCulate . :PSCan . . :AVERage . . . :TYPE MINimum|MAXimum|SCALar| OFF

CALCulate:PSCan:AVERage:TYPEMINimum|MAXimum|SCALar|OFF

Setting of the averaging procedure for the panorama-scan data. Each FFT sample is processed
separately, e.g. for the MAXimum type a maximum value is kept for each bin in a panorama scan.

Parameters

MINimum Keep minimum value of obtained measurements

MAXimum Keep maximum value of obtained measurements

SCALar Average measurements over the measurement time

OFF Do not process obtained measurements

Example

CALCulate:PSCan:AVERage:TYPE MINimum

CALCulate . :PSCan . . :AVERage . . . :TYPE?

CALCulate:PSCan:AVERage:TYPE?

Query of the averaging procedure for the panorama-scan data.

Result

MIN, MAX, SCAL, OFF
