Getting Started with the Instrument R&S FSMR
1313.9617.12 1.16 E-2
Getting Started with the Instrument
The following section describes how to activate the instrument and how to connect external devices
such as printer and monitor.
Chapter 2 explains the operation of the instrument using simple measurement examples.
Optional notice heading
Prior to switching on the instrument, make sure that the following conditions are fulfilled:
• The instrument cover is in place and tightly screwed on
• Fan
openings are not obstructed
• Signal levels at the inputs are within specified limits
• Signal outputs are connected correctly and not overloaded.
Any non-compliance may cause damage to the instrument
Preparing the Instrument for Operation
remove protective caps
Take the instrument out of the packaging and check whether the
items listed in the packing list and in the lists of accessories are all
included.
Remove the two protective covers from the front and rear of the
R&S FSMR and carefully check the instrument for damage.
Should the instrument be damaged, immediately notify the carrier
and keep the box and packing material.
For further transport or shipment of the R&S FSMR, the original
packing should be used. It is recommended to keep at least the two
protective covers of the front and rear panels in order to prevent
damage to the controls and connectors.
Setting Up the Instrument
Standalone Operation
The instrument is designed for use under general laboratory conditions. The ambient conditions required
at the site of operation are as follows:
Wrist strap with cord
Buildin g ground
Floor mat
Ground connection
of operational site
Heel strap
• The ambient temperature must be in the range specified in
the data sheet.
• All fan openings must be unobstructed and the air flow at
the rear panel and at the side-panel perforations must be
unimpeded. The distance to the wall should be at least
10 cm.
• T
he
mounting surface should be flat.
• To avoid damage of electronic components of the DUT

R&S FSMR Getting Started with the Instrument
1313.9617.12 1.17 E-2
Safety Instruction for Instruments with Tiltable Feet
The feet must be fully folded in or out. Only in this way can the stability of the
instrument be guaranteed and reliable operation be ensured. With the feet out, the total
load for the feet must not exceed 500 N (own weight and additional units put onto the
instrument). These units must be secured against slipping (e.g. by locking the feet of
the unit at the top side of the enclosure).
<500N
When shifting the instrument with the feet out, the feet might collapse and fold in. To
avoid injuries, the instrument must therefore not be shifted with the feet out.
The instrument can be operated in any position.
Rackmounting
For rack installation, ensure that the air flow at the side-panel perforations and the air
exhaust at the rear panel are not obstructed.
The instrument may be installed in a 19" rack by using a rack adapter kit (Order No. see data sheet).
The installation instructions are part of the adapter kit.
EMC Safety Precautions
In order to avoid electromagnetic interference (EMI), the instrument may be operated only with all covers
closed. Only adequately shielded signal and control cables may be used (see recommended accessories).
Page 29
Getting Started with the Instrument R&S FSMR
1313.9617.12 1.18 E-2
Connecting the Instrument to the AC Supply
The R&S FSMR is equipped with an AC voltage selection feature and will automatically adapt itself to
the applied AC voltage (range: 100 to 240 V AC, 40 to 400 Hz). External voltage selection or adaptation
of the fuses are not necessary. The AC power connector is located on the rear panel (see below).
o
I
Power connector
Connect the instrument to the AC power source using the AC
power cable delivered with the instrument.
As the instrument is designed according to the regulations for
safety class EN61010, it must be connected to a power outlet
with earthing contact.
Switching the Instrument On/Off
Do not power down during booting.
Such a switch-off may lead to corruption of the hard disk files

Page 30
R&S FSMR Getting Started with the Instrument
1313.9617.12 1.19 E-2
Switching On the Instrument
In order to switch on the R&S FSMR, set the power switch on the rear panel to position I.
Set the R&S FSMR to operating mode by pressing the ON/STANDBY key on the front panel. The
green LED must be illuminated.
Startup Menu and Booting
After switching on the instrument, a message indicating the installed BIOS version (e.g. Analyzer BIOS
Rev. 1.2) appears on the screen for a few seconds.
Subsequently Windows XP is booted first and after that the instrument firmware will boot. As soon as
the boot process is finished the instrument will start measuring. The settings used will be the one that
was active when the instrument was previously switched off, provided no other device configuration than
FACTORY had been selected with STARTUP RECALL in the FILE menu.
Switching Off the R&S FSMR
Switch the ON/STANDBY key on the front panel to standby mode by pressing it once.
The R&S FSMR will write the current instrument settings to disk before performing a Windows XP
shutdown. At the end of the shutdown procedure the power supply will be switched to STANDBY mode.
The yellow LED must be illuminated.
Only when removing the R&S FSMR completely from the AC power source:
Set the power switch at the rear panel to position 0.
Operating the R&S FSMR with the Removable Hard Disk Option R&S FSMR-B18
The R&S FSMR-B18 option allows the instrument to be operated with differently configured hard disks.

same time the data entry for the delay time is opened.
3. Define the delay time
Enter the required response time in minutes and confirm the entry using the ENTER key.
The screen will be blanked out after the selected time period has elapsed.
Hard disk:
A power-save mode is preset for the built-in hard disk which is automatically closed down 15 minutes
after the last access.
Recalling the Most Recent Instrument Settings
The R&S FSMR stores its current instrument settings onto the hard disk every time it is switched off via
the ON/STANDBY key. After each power-on, the R&S FSMR is reloaded with the operational
parameters which were active just prior to the last power-off (STANDBY or AC power OFF) or were set
with STARTUP RECALL (see Chapter 4 "Saving and Recalling Data Sets").
Storing the current instrument se
ttings is not possible if the instrument is switched off
using the POWER ON switch at the rear panel or when unplugging the mains cord.
After power-on the instrument settings stored previously on the hard disk will be
loaded in this case.
Function Test
After turning on the AC power, the R&S FSMR will display the following message on the display screen:
Rohde & Schwarz GmbH & Co. KG
Analyzer BIOS Vx.y
After appearance of the above message, a selftest of the controller hardware is performed.
Subsequently, the Windows XP controller boots and the measurement screen will appear.
The system self-alignment is activated via CAL key, CAL TOTAL softkey. The individual results of the
self-alignment (PASSED / FAILED) can be displayed in the CAL menu (CAL RESULTS).
With the aid of the built-in selftest functions (SETUP key, SERVICE, SELFTEST soft keys), the
functional integrity of the instrument can be verified and/or defective modules can be localized.

1313.9617.12 1.36 E-2
Connection of USB Devices
Up to two USB devices can be directly connected to the analyzer via the USB interface on the rear of the
R&S FSMR. This number can be increased as required by interconnecting USB hubs.
Owing to the wide variety of available USB devices, the R&S FSMR can be expanded with almost no
limitations. The following list shows a selection of USB devices suitable for the R&S FSMR:
• Power Sensor R&S NRP-Z11 or R&S NRP-Z21 (Adapter Cable R&S NRP-Z4 required)
• Pendrive (memory stick) for easy data transfer from/to the PC (e.g. firmware updates)
• CD-ROM drive for easy installation of firmware applications
• PC keyboard for entering comments, file names, etc
• Mouse for easy operation of Windows dialogs
• Printer for documentation of measurement results
• Modem for remote control of the R&S FSMR over great distances
The installation of USB devices is quite simple under Windows XP since all USB devices are Plug&Play.
Apart from the keyboard and the mouse, all USB devices can be connected to or disconnected from the
R&S FSMR while the instrument is running.
After the instrument is connected to the USB interface, Windows XP automatically searches for a
suitable device driver.
If Windows XP does not find a suitable driver, you will be prompted to specify a directory where the
driver software can be found. If the driver software is on a CD, a USB CD-ROM should first be
connected to drive to the R&S FSMR.
As soon as the connection between the R&S FSMR and the USB device is interrupted, Windows XP will
again recognize the modified hardware configuration and will deactivate the corresponding device driver.
Example:
Connecting a pendrive (memory stick) to the R&S FSMR:
1. After the pendrive is connected to the USB interface, Windows XP will recognize the newly
connected hardware:
2. Windows XP installs the corresponding driver.
After successful installation, XP signals that the unit is ready for operation:
3. The pendrive is now available as a new drive and is displayed in Windows Explorer:
Page 48
R&S FSMR Connection of USB Devices
1313.9617.12 1.37 E-2
The pendrive can be used as a normal drive to load or save files.
4. If the pendrive is no longer required or if files are to be transferred to another computer, the
pendrive is simply disconnected. Windows XP will then deactivate the driver.
If the corresponding drive is still selected in Explorer, an error message will be displayed indicating
that the drive is no longer available.

2 Getting Started
This chapter provides a fast introduction to operation by guiding the user step by step through
measurement examples .
Before starting any measurement with the FSMR, please note the instructions given in chapter 1 of the
users manual for putting the instrument into operation. In chapter 3 you will find detailed information on
customizing the instrument and the display.
For a systematic explanation of all menus, functions and parameters and background information refer
to the reference part in chapter 4.
Instrument overview
The R&S FSMR is a very versatile instrument that combines many measurement capabilities required
for calibration, troubleshoot and development into a single box instrument. The following functions are
included:
• RF Power Meter, for highest accuracy RF power measurement.
• RF Level Meter, for measurements of low level signals.
• Modulation Analyzer, for AM/FM and 4M modulated signals.
• Audio Analyzer, for Audio Signal level and distortion, using the Audio input.
• Frequency Counter, fastest frequency measurements with „mHz“-resolution.
• Spectrum Analyzer, for high performance spectral analysis capabilities.
The R&S FSMR still offers an easy-to-use operation which does not require expert knowledge to
perform the basic measurements.
This product note is designed to explain the functions and operation of the Measuring Receiver R&S
FSMR. In the following descriptions, each step is explained in detail so that the instrument can be
immediately used without the need for learning all of the available functions.
Setup the instruments
Most of the following examples use the same test setup. To perform the measurements, in addition to
the Measuring Receiver R&S FSMR a signal generator and a power sensor is required. The examples
in this paper will require a single, stable RF test signal at lower RF frequencies (for example 100 MHz).
The generator shall offer analog modulation capabilities (at least AM modulation) at a variable
modulation rate from 1 kHz to 3 kHz and 30 % modulation depth.
For the audio measurement examples a LF generator is required. Most of the R&S signal generators
are equipped with a modulation generator which is sufficient for these measurements (for example R&S
SML, R&S SMIQ).
The power sensor used in the examples shall be one of the sensors from the R&S NRP series. There
are many different sensors available, a terminating average power sensor will best fit to the
requirements (for example R&S NRP-Z21)

AVERAGING
[10]
The FSMR is now performing a calibrated measurement at – 110
dBm. The reading will be flickering due to a low signal to noise ratio.
For a more stable reading, the FSMR does offer several functions.
The stability of a low level measurement is mainly depending on the
measurement time. A longer acquisition of the signal does allow for
a more accurate measurement. The averaging of several single
acquisitions will lead to an effective longer measurement time.
Press the RF LEVEL hotkey.

bandwidth. The acquisition bandwidth (DEMOD BW) of the FSMR
can be set in the BW menu, the preset value is 12.5 kHz. The
bandwidth must be set wide enough to capture the maximum
frequency deviation of the input signal. In this example, the
frequency deviation is set to 3 kHz and the default bandwidth is 12.5
kHz.
Note: The wideband detection is not only suitable for unstable signals,
it can also be used to accurately measure modulated signals
Next steps:
The following steps will be performed as described in the previous
example (Tuned RF Level).

The softkeys have different functions depending on the instrument state. Therefore, their labeling can be
varied. The labeling of all softkeys which call a submenu includes a ⇓ arrow.
The function and current state of the softkeys is indicated in the label by different texts and colors. The
color assignment is factory-set as follows:
Table 3-1 Factory-set color assignment of soft keys
Softkey color Meaning
gray Softkey switched off
green Softkey switched on
red Softkey switched on and data entry active
These colors can be changed by the user as desired in the DISP - CONFIG DISPLAY menu.
A softkey is switched on or off by pressing the respective hardkey (see following section "Setting the
Parameters").
Softkeys are masked out, too, if the functionality which they represent is not available. A dis tinction has
to be made between two cases:
• If an instrument function depends on an option, and if this option is not fitted, the associated softkey is
masked out,.
• If the instrument function is not available temporarily due to specific settings, the softkey is displayed
without the 3D frame.
The label
on the r ight lower corner of the softkey area indicates that a s ide menu is available. T he
side menu is called by pressing the NEXT key.

Calling and Changing the Menus
The operation of the s pectrum analyzer is menu-controlled via k eys and s oftkeys. Various softkey
menus are displayed depending on the instrument status. The individual menus constitute the so-called
menu tree. The top menu (the root of the menu tree) is always called by means of a keystroke. Arrows
at the lower edge of the softkey area indicate whether a supplementary menu can be entered or not.
Softkeys with an arrow allow for branching into further menus (so-called submenus): The field "
" at the
lower right side of the softkey area indicates that this menu has a side menu.
The menu change keys on the front panel below the softkey area allow for switching between the main
menu and the side menus and submenus.
NEXT
The NEXT key calls the side menu.
PREV
The PREVIOUS key returns to the next higher menu.
Several menus provide for automatic change, i.e., return to the next higher
menu is caused automatically after pressing a softkey.
Selection of a submenu is always effected via a softkey.

Setting Parameters
Parameters are set either by simple selection (selection parameters) or by (alpha)numeric entries in
data entry windows or tables.
The numeric keypad on the f ront panel, an ex ternal keyboard (optional), a s pinwheel and the c ursor
keys are provided for the entry of instrument parameters in an entry window or in a table.
The external keyboard is optional. If it is not fitted, the help line editor is called automatically for entry of
alphanumeric parameters. The help line editor provides for selection of individual letters and a number
of special characters which are copied into the actual entry window.

parameter.
A "-" is inserted at the cursor position in case of an
alphanumeric parameter.
• Unit keys (GHz/-dBm, MHz/dBm, kHz/dB and Hz/dB)
– Provide the numeric value entered with the selected unit
and terminate the entry.
The unit k eys are all as signed the value "1" for
dimensionless quantities or for level entries (e.g., in dB).
The unit k eys thus assume the f unction of an ENTER
key. The same applies for an alphanumeric entry.
– Open and close the selection windows of tables.
• BACK key
– Deletes the character left to the c ursor with numeric
entry.
– Allows for toggling between the current and the previous

Spinwheel and Cursor Keys
The spinwheel and the cursor keys are arranged besides the numeric keypad.
The spinwheel has various functions:
• With numeric entry, the ins trument parameter is incremented (turning
clockwise) or decremented (turning counterclockwise) at a defined step
size.
• In tables, the s pinwheel can be us ed to s hift the cursor horizontally or
vertically when no entry window is open. The direction (horizontal/ vertical)
is switched over using the cursor keys.
• The spinwheel is used with the help- line editor to s elect the individual
letters.
• It can be used to shift markers, display lines, limit lines etc.
• Pressing the spinwheel terminates the input of parameters.
In tables, the c ursor keys are used to shift the cursor between the lines and
columns of the table.

Selection and Setting of Parameters via Tables
The spectrum analyzer uses numerous tables for display and configuration of instrument parameters.
The tables differ considerably in the num ber of lines, columns and inscriptions. The basic steps of
operation for the selection and setting of parameters are, however, the same for all tables. Shown below
is the typical entry of parameters into a table.
Note:
Most of the tables are coupled to a softkey menu which provides further functions for editing table
entries such as deletion of tables , copying of lines or columns, marking of table elements , restoring
default states.
The definition of individual tables and the operation of particular editing functions can be looked up in the
description of the corresponding softkey menu.
