instrument be guaranteed and reliable operation be ensured. With the feet out, the total
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
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).
1313.9617.12 1.17 E-2
Getting Started with the Instrument R&S FSMR

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).
Connect the instrument to the AC power source using the AC

In standby mode, the AC power voltage is present within the instrument
STANDBY - ON/STANDBY switch is not pressed.
The yellow LED (STANDBY) is illuminated. Only the power supply is supplied with power and the quartz oven is maintained at normal operating temperature.
1313.9617.12 1.18 E-2
R&S FSMR Getting Started with the Instrument
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

Connection of USB Devices R&S FSMR

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:
1313.9617.12 1.36 E-2
R&S FSMR Connection of USB Devices
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.

R&S FSMR Instrument overview

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)

The measurement of an unstable signal requires the measuring receiver to use a wide bandwidth. The FSMR offers a wideband detector mode to acquire wideband signals with high accuracy
In the RF LEVEL menu press the DETECTOR WIDE softkey.
The wideband detector mode acquire signals with the full acquisition
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).

3 Manual Operation
Chapter 3 provides an overview of the operating concept and the basic steps of manual operation of the R&S FSMR. This includes a des cription of the s creen, of the control of menus and of the setting of parameters. An overview of the menus will be listed at the end of this chapter.
The functions of the menus are described in detail in Chapter 4. Chapter 2 contains a short introduction on step-by-step simple measurements. The remote control of the instrument is described in Chapters 5, 6 and 7
The operation of the spectrum analyzer is menu-controlled via keys, hotkeys and softkeys. The setting of the ins trument and test parameters in the m enus is made either directly via s oftkeys or by entry of values in entry fields and by selection in tables . The operating mode and the s creen mode is selected via the hotkeys. If required, data entry windows and tables are superimposed on the screen.

The Screen

The screen informs continuously on the r esults and parameters of the selected measuring functions. It shows the as signment of the s oftkeys and m enus, which are required for setting the measuring parameters. The display of test results, the s oftkey labeling and the type of menu depend on the selected measuring function. The screen is subdivided into three areas:

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.
The keys reach a particular position in the string.
The keys

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.
1. Activating the table
2. Selection of the parameter
If the menu has only one table, the latter is activated
automatically subsequent to c alling this menu in most cases and the m arking cursor is positioned to the top field of the left column.
If the m enu contains various tables, the table of interest
must be selected using the s oftkey which is labeled w ith the title of the table.
