Connecting an External Monitor
Screen resolution and format
The touchscreen of the R&S FSMR3 is calibrated for a 16:10 format. If you
connect a monitor or projector using a different format (e.g. 4:3), the calibration is not correct and the screen does not react to your touch actions properly.
The touchscreen has a screen resolution of 1280x800 pixels. Usually, the
display of the external monitor is a duplicate of the instrument's monitor.
If you configure the external monitor to be used as the only display in the
Windows configuration dialog box ("Show only on 2"), the maximum screen
resolution of the monitor is used. In this case, you can maximize the
R&S FSMR3 application window and see even more details. You cannot
change the monitor's screen resolution via the standard Windows configuration dialog box.
However, you can restore the default instrument resolution (1280x800) on
the monitor using the instrument function "Setup" > "Display" > "Configure
Monitor" > "Screen Resolution: Restore to default".
Preparing for Use
The R&S FSMR3 supports a minimum resolution of 1280x768 pixels.
1. Connect the external monitor to the R&S FSMR3.
2. Press the [Setup] key.
3. Press the "Display" softkey.

R&S®FSMR3000
Windows Operating System
Tested software
The drivers and programs used on the instrument under Windows 10 are adapted
to the instrument. Only install update software released by Rohde & Schwarz to
modify existing instrument software.
You can install additional software on the instrument; however, additional software can impair instrument function. Thus, run only programs that
Rohde & Schwarz has tested for compatibility with the instrument software.
The following program packages have been tested:
●
Symantec Endpoint Security – virus-protection software
●
FileShredder - for reliable deletion of files on the hard disk
Service packs and updates
Microsoft regularly creates security updates and other patches to protect Windows-based operating systems. These are released through the Microsoft Update
website and associated update server. Instruments using Windows, especially
those that connect to a network, should be updated regularly.
Preparing for Use
Firewall settings
A firewall protects an instrument by preventing unauthorized users from gaining
access to it through a network. Rohde & Schwarz highly recommends the use of
the firewall on your instrument. Rohde & Schwarz instruments are shipped with
the Windows firewall enabled and preconfigured in such a way that all ports and
connections for remote control are enabled.
Note that changing firewall settings requires administrator rights.
Virus protection
Take appropriate steps to protect your instruments from infection. Use strong firewall settings and scan any removable storage device used with a
Rohde & Schwarz instrument regularly. It is also recommended that you install
anti-virus software on the instrument. Rohde & Schwarz does NOT recommend
running anti-virus software in the background ("on-access" mode) on Windowsbased instruments, due to potentially degrading instrument performance. However, Rohde & Schwarz does recommend running it during non-critical hours.
For details and recommendations, see the following Rohde & Schwarz white
paper:

Passwords
For all default user accounts, the initial password is 894129. Note that this password is very weak, and it is recommended that you change the password for both
users after initial login. An administrator can change the password in Windows 10
for any user at any time via "Start > Settings > Account > SignIn Options > Password > Change".
Auto-login
When shipped, the instrument automatically logs on the default "Instrument" user
to Windows 10 using the default password. This function is active until an administrator explicitly deactivates it or changes the password.
Changing the password and use of auto-login function
Note that when you change the default password, the default auto-login
function no longer works!
Preparing for Use

Considerations for Test Setup
Preparing for Use
4.13 Performing a Self-Alignment
When strong temperature changes occur in the environment of the R&S FSMR3,
or after updating the firmware, you have to perform a self-alignment to align the
data to a reference source.
During self-alignment, do not connect a signal to the RF input connector. Running
a self-alignment with a signal connected to the RF input can lead to false measurement results.
Performing a self-alignment
Before performing this functional test, make sure that the instrument has reached
its operating temperature (for details, refer to the data sheet).
A message in the status bar ("Instrument warming up...") indicates that the operating temperature has not yet been reached.
Depending on the installation settings, an automatic self-alignment is performed
each time the instrument is switched on. A dialog is displayed indicating how
much warm-up time is still required before self-alignment can be performed.
1. Press the [Setup] key.
2. Press the "Alignment" softkey.
3. Select the "Start Self Alignment" button in the "Alignment" dialog box.
Once the system correction values have been calculated successfully, a message is displayed.
To display the alignment results again later
●
Press the [SETUP] key.
●
Press the "Alignment" softkey.

5.1.8 Trigger Input / Output
Use the female Trigger 1 Input/Output connector to input an external trigger or
gate data. Thus, you can control the measurement using an external signal. The
voltage levels can range from 0.5 V to 3.5 V. The default value is 1.4 V. The typical Input impedance is 10 kΩ.
The rear panel provides two more Trigger Input / Output connectors, see
Chapter 5.2.7, "Trigger 2/3 In/Out", on page 46.
5.1.9 RF Input 50 Ohm
Provides RF input from a connected device under test (DUT) to the R&S FSMR3,
which is then analyzed in an RF measurement. Connect the DUT to the "RF
Input" connector on the R&S FSMR3. Do not overload the input. For maximum
allowed values, see the data sheet.
The RF input can be coupled to the DUT by alternating current (AC) or direct current (DC). AC coupling blocks any DC voltage from the input signal. This is the
default setting to prevent damage to the instrument. However, some specifications require DC coupling. In this case, you must protect the instrument from
damaging DC input voltages manually. For details, refer to the data sheet. For
details on coupling, see the chapter on radio frequency input in the R&S FSMR3
user manual.
See also Chapter 4.14, "Considerations for Test Setup", on page 30.
5.1.10 Probe
The R&S FSMR3 provides a connector for supply voltages of +15 V to -12 V and
ground for active probes and preamplifiers. A maximum current of 140 mA is
available. This connector is suitable as a power supply for high-impedance
probes.
5.1.11 AF Out and Volume

5. Tap the "Calibration Frequency RF" option. Leave the frequency at the default
64 MHz, with a narrowband spectrum.
The calibration signal is now sent to the RF input of the R&S FSMR3. By
default, a continuous frequency sweep is performed, so that the spectrum of
the calibration signal is now displayed in the standard level versus frequency
diagram.

Activating Additional Measurement Channels
You see the spectrogram compared to the standard spectrum display. Since
the calibration signal does not change over time, the color of the frequency
levels does not change over time, i.e. vertically. The legend at the top of the
spectrogram window describes the power levels the colors represent.

6.3 Activating Additional Measurement Channels
The R&S FSMR3 features multiple measurement channels, i.e. you can define
several measurement configurations in parallel and then switch between the
channels automatically to perform the measurements sequentially. We will demonstrate this feature by activating additional measurement channels for a different
frequency range, a zero span measurement, and an I/Q analysis.
To activate additional measurement channels

7.1.1 Channel Bar
Using the R&S FSMR3 you can handle several different measurement tasks
(channels) at the same time (although they can only be performed asynchronously). For each channel, a separate tab is displayed on the screen. To switch
from one channel display to another, simply select the corresponding tab.
If many tabs are displayed, select the tab selection list icon at the right end of the
channel bar. Select the channel you want to switch to from the list.
MultiView tab
An additional tab labeled "MultiView" provides an overview of all active channels
at a glance. In the "MultiView" tab, each individual window contains its own channel bar with an additional button. Tap this button, or double-tap in any window, to
switch to the corresponding channel display quickly.
Icons in the channel bar
The yellow star icon on the tab label (sometimes referred to as a "dirty flag")
indicates that invalid or inconsistent data is displayed, that is: the trace no longer
matches the displayed instrument settings. Thiscan happen, for example, when
you change the measurement bandwidth, but the displayed trace is still based on
the old bandwidth. As soon as a new measurement is performed or the display is
updated, the icon disappears.

points is changed temporarily (graphical zoom).
Operating the Instrument
Touchscreen Gestures
For example:
●
Dragging horizontally in a spectrum display changes the center frequency.
●
Dragging vertically in a power vs frequency (spectrum) or power vs. time display changes the reference level (for absolute scaling) or the min and max
power values (for relative scaling).
●
Dragging horizontally in a time domain display changes the trigger offset value
(if available, not in free run).
●
Spreading or pinching a spectrum display changes the center frequency and
span (horizontal) or reference level and range (vertical), or a combination of
these settings (diagonal).
●
Spreading or pinching a time domain display changes the sweep time and
trigger offset (horizontal) or reference level position and range (vertical), or a
combination of these settings (diagonal).
You can prevent the firmware from changing specific settings using the options in
the context menu for the measurement zoom icon. By default, the reference level
is locked and thus not changed automatically due to touch gestures.

7.5 Displaying Results
The R&S FSMR3 provides several instrument applications for different analysis
tasks and different types of signals, for example the Measuring Receiver application, the Spectrum application or the I/Q Analyzer. For each application, a new
measurement channel is created and displayed in a separate tab on the screen.
The results of a measurement channel can be evaluated in many different ways,
both graphically and numerically. For each evaluation method the results are displayed in a separate window in the tab.
The R&S FSMR3 allows you to configure the display to suit your specific requirements and optimize analysis.
7.5.1 Activating and Deactivating Channels
When you activate an application, a new measurement channel is created which
determines the measurement settings for that application. The same application
can be activated with different measurement settings by creating several channels for the same application. Whenever you switch channels, the corresponding
measurement settings are restored. Each channel is displayed in a separate tab
on the screen.
An additional tab ("MultiView") provides an overview of all currently active channels at once.
Only one measurement can be performed at any time, namely the one in the currently active channel. However, in order to perform the configured measurements
consecutively, a Sequencer function is provided.

Displaying Results
7.5.2 Laying out the Result Display with the SmartGrid
Measurement results can be evaluated in many different ways, for example
graphically, as summary tables, statistical evaluations etc. Each type of evaluation is displayed in a separate window in the channel tab. Up to 16 individual windows can be displayed per channel (i.e. per tab). To arrange the diagrams and
tables on the screen, the Rohde & Schwarz SmartGrid function helps you find the
target position simply and quickly.
(For details on evaluation methods see the User Manual.)
Principally, the layout of the windows on the screen is based on an underlying
grid, the SmartGrid. However, the SmartGrid is dynamic and flexible, allowing for
many different layout possibilities. The SmartGrid functionality provides the following basic features:
●
Windows can be arranged in columns or in rows, or in a combination of both.
●
Windows can be arranged in up to four rows and four columns.
●
Windows are moved simply by dragging them to a new position on the screen,
possibly changing the layout of the other windows, as well.
●
All evaluation methods available for the currently selected measurement are
displayed as icons in the evaluation bar. If the evaluation bar contains more
icons than can be displayed at once on the screen, it can be scrolled vertically.
The same evaluation method can be displayed in multiple windows simultaneously.
●
New windows are added by dragging an evaluation icon from the evaluation
bar to the screen. The position of each new window depends on where you
drop the evaluation icon in relation to the existing windows.
●
All display configuration actions are only possible in SmartGrid mode. When
SmartGrid mode is activated, the evaluation bar replaces the current softkey
menu display. When the SmartGrid mode is deactivated again, the previous
softkey menu display is restored.

SmartGrid display
During any positioning action, the underlying SmartGrid is displayed. Different
colors and frames indicate the possible new positions. The position in the SmartGrid where you drop the window determines its position on the screen.
Figure 7-8: Moving a window in SmartGrid mode
The brown area indicates the possible "drop area" for the window, i.e. the area in
which the window can be placed. A blue area indicates the (approximate) layout
of the window as it would be if the icon were dropped at the current position. The
frames indicate the possible destinations of the new window with respect to the
existing windows: above/below, right/left or replacement (as illustrated in Fig-

ure 7-9). If an existing window would be replaced, the drop area is highlighted in a
darker color shade.
Positioning the window
The screen can be divided into up to four rows. Each row can be split into up to
four columns, where each row can have a different number of columns. However,
