charge and installed by Rohde & Schwarz, is also available from the taskbar or "Start"
menu.
For details on the IECWIN tool, see Chapter 11.4, "The IECWIN tool", on page 337.
All necessary system settings can be defined in the "Start > Settings" menu.
For required settings, refer to the Windows 10 documentation and to the hardware
description.
Windows 10 requires that users identify themselves by entering a user name and password in a login window. By default, the R&S FSMR3 provides two user accounts:
●
"Instrument" : a standard user account with limited access
●
"Admin" or "Administrator" (depends on firmware image): an administrator
account with unrestricted access to the computer/domain
Some administrative tasks require administrator rights (e.g. the configuration of a LAN
network). Refer to the description of the basic instrument Setup ([Setup] menu) to find
out which functions are affected.
Secure user mode
If the secure user mode option (R&S FSMR3-K33) is installed, an additional account is
provided: the "SecureUser".
The "SecureUser" is a standard user account with limited functionality. In particular,
administrative tasks such as LAN configuration or general instrument settings are not
available. Furthermore, for a "SecureUser", data that the R&S FSMR3 normally stores
on the solid-state drive is redirected to volatile memory instead. You can access data
that is stored in volatile memory during the current instrument session. However, when
the instrument’s power is removed, all data in volatile memory is erased.
For details, see Chapter 9.2, "Protecting data using the secure user mode",
on page 237.
Passwords
For all default user accounts, the initial password is 894129. Note that this password is
very weak, and we strongly recommend 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".

Preparing for use
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!
In this case, you must enter the new password manually to log on.
Adapting the auto-login function to a new password
If you change the password that is used during auto-login, this function no longer
works. Adapt the settings for the auto-login function first.
1. Select the "Windows" icon in the toolbar to access the operating system of the
R&S FSMR3 (see also "To access the "Start" menu" on page 20).
2. Open the C:\R_S\INSTR\USER\user\AUTOLOGIN.REG file in any text editor
(e.g. Notepad).
3. In the line "DefaultPassword"="894129", replace the default password
(894129) by the new password for automatic login.
4. Save the changes to the file.
5. In the Windows "Start" menu, select "Run".
The "Run" dialog box is displayed.
6. Enter the command C:\R_S\INSTR\USER\user\AUTOLOGIN.REG.

In a table, move the selection bar horizontally.
●
In windows or dialog boxes with horizontal scroll bar, move the scroll bar.
●
The [Undo] key reverts the previous action, i.e. the status before the previous
action is retrieved.
The Undo function is useful, for example, if you are performing a zero span measurement with several markers and a limit line defined and accidentally select a different measurement. In this case, many settings would be lost. However, if you
press [Undo] immediately afterwards, the previous status is retrieved, i.e. the zero
span measurement and all settings.
●
The [Redo] key repeats the previously reverted action, i.e. the most recent action is
repeated.
The [Undo] function is not available after a [Preset] or "Recall" operation. When these
functions are used, the history of previous actions is deleted.
4.3.1.8 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 Chap-
ter 4.3.2.7, "Trigger 2/3 In/Out", on page 36.
4.3.1.9 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.

This chapter introduces the most important functions and settings of the R&S FSMR3
step by step. The complete description of the functionality and its usage is given in the
R&S FSMR3 User Manual. Basic instrument operation is described in Chapter 4.5,
"Operating the instrument", on page 58.
Prerequisites
●
The instrument is set up, connected to the mains system, and started up as described in Chapter 4.2, "Preparing for use", on page 12.
For these first measurements, you use the internal calibration signal, so you do not
need any additional signal source or instruments. Try out the following:
● Measuring a basic signal in the spectrum application.............................................39
● Displaying a spectrogram........................................................................................41
● Activating additional measurement channels..........................................................43
● Performing sequential measurements.................................................................... 47

● Zooming into the display permanently.................................................................... 53
● Saving settings........................................................................................................56
● Printing and saving results......................................................................................57
4.4.1 Measuring a basic signal in the spectrum application
We will start out by measuring a basic signal, using the internal calibration signal as
the input.
To display the internal 64 MHz calibration signal
1. Press the [PRESET] key to start out in a defined instrument configuration.
2. Press the [Setup] key on the front panel.
3. Tap the "Service + Support" softkey.
4. Tap the "Calibration Signal" tab.
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.

Instrument warmup time
Note that the instrument requires an initial warmup time after switching it on. A message in the status bar ("Instrument warming up...") indicates that the operating temperature has not yet been reached. Wait until this message is no longer displayed before
you start a measurement.
To optimize the display
To optimize the display for the calibration signal, we will adjust the main measurement
settings.
1. Set the center frequency to the calibration frequency:
a) Tap the "Overview" softkey to display the configuration "Overview".
b) Tap the "Frequency" button.
c) In the "Center" field, enter 64 on the number pad on the front panel.
d) Press the "MHz" key next to the number pad.
2. Reduce the span to 20 MHz:
a) In the "Span" field of the "Frequency" dialog box, enter 20
MHz.
b) Close the "Frequency" dialog box.
3. Set the reference level to -25 dBm:
a) In the configuration "Overview", tap the "Amplitude" button.
b) In the "Value" field of the "Amplitude" dialog box, enter -25 dBm.
The display of the calibration signal is now improved. The maximum at the center
frequency (=calibration frequency) of 64 MHz becomes visible.

4.4.2 Displaying a spectrogram
In addition to the standard "level versus frequency" spectrum display, the R&S FSMR3
also provides a spectrogram display of the measured data. A spectrogram shows how
the spectral density of a signal varies over time. The x-axis shows the frequency, the yaxis shows the time. A third dimension, the power level, is indicated by different colors.
Thus you can see how the strength of the signal varies over time for different frequencies.
1. Tap the "Overview" softkey to display the general configuration dialog box.
2. Tap the "Display Config" button.
The SmartGrid mode is activated, and the evaluation bar with the available evalua-
tion methods is displayed.
3.
Drag the "Spectrogram" icon from the evaluation bar to the diagram area. The blue
area indicates that the new diagram would replace the previous spectrum display.
Since we do not want to replace the spectrum, drag the icon to the lower half of the
display to add an additional window instead.

4.4.3 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
1. Press the [Mode] key on the front panel.
2. On the "New Channel" tab of the "Signal + Spectrum Mode" dialog box, tap the

4.5.1.3 Marker information
Marker information is provided either in the diagram grid or in a separate marker table,
depending on the configuration.
Marker information in diagram grid
Within the diagram grid, the x-axis and y-axis positions of the last two markers or delta
markers that were set are displayed, if available, as well as their index. The value in
the square brackets after the index indicates the trace to which the marker is assigned.
(Example: M2[1] defines marker 2 on trace 1.) For more than two markers, a separate
marker table is displayed beneath the diagram by default.
Marker information in marker table
In addition to the marker information displayed within the diagram grid, a separate
marker table may be displayed beneath the diagram. This table provides the following
information for all active markers:
Type Marker type: N (normal), D (delta), T (temporary, internal), PWR (power sensor)
Ref Reference (for delta markers)
Correction data is not used.
Trc Trace to which the marker is assigned

Touch gestures in diagrams change measurement settings
When you change the display using touch gestures, the corresponding measurement
settings are adapted. This is different to selecting an area on the screen in zoom
mode, where merely the resolution of the displayed trace points is changed temporarily
(graphical zoom).
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.
Mouse vs. touch actions
Any user interface elements that react to actions by a mouse pointer also react to finger gestures on the screen, and vice versa. The following touch actions correspond to
mouse actions:

4.5.5 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.
Touch, then drag and release

4.5.5.1 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.

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.
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.

Background information: the smartgrid principle
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 4-30: 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 Figure 4-31). 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, rows
always span the entire width of the screen and may not be interrupted by a column. A
single row is available as the drop area for the window in the SmartGrid. The row can
be split into columns, or a new row can be inserted above or below the existing row (if
the maximum of 4 has not yet been reached).

Once the evaluation icon has been dropped, icons in each window provide delete and
move functions.
The "Move" icon allows you to move the position of the window, possibly changing the
size and position of the other displayed windows.
The "Delete" icon allows you to close the window, enlarging the display of the remaining windows.
How to activate smartgrid mode
All display configuration actions are only possible in SmartGrid mode. In SmartGrid
mode the evaluation bar replaces the current softkey menu display. When the SmartGrid mode is deactivated again, the previous softkey menu display is restored.
► To activate SmartGrid mode, do one of the following:
●
Select the "SmartGrid" icon from the toolbar.
● Select the "Display Config" button in the configuration "Overview".
● Select the "Display Config" softkey from the [Meas Config] menu.
The SmartGrid functions and the evaluation bar are displayed.

Applications
R&S multiview
The R&S FSMR3 is a dedicated Measuring Receiver whose main feature is the measuring receiver application.
When equipped accordingly (with optional hardware or software), it is able to provide
several additional applications for different analysis tasks (for example the spectrum
application).
When you activate an application, the R&S FSMR3 creates a new measurement channel which in turn determines the measurement settings for that application. You can
use the same application with different measurement settings by creating several
channels for the same application. Each channel is represented by a separate tab on
the screen.
Note that the number of channels can be limited by the available memory of the
R&S FSMR3.

Applications
Running a sequence of measurements
The instrument can only activate one specific channel at any time. Thus, 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, which changes the channel of the instrument as
required. If activated, the measurements configured in the currently defined "Channel"s
are performed one after the other in the order of the tabs.
For each individual measurement, the sweep count is considered. Thus, each measurement may consist of several sweeps. The currently active measurement is indicated by a

●
Single Sequence
Similar to single sweep mode; each measurement is performed once, until all measurements in all defined "Channel"s have been performed.
●
Continuous Sequence
Similar to continuous sweep mode; the measurements in each defined "Channel"
are performed one after the other, repeatedly, in the same order, until sequential
operation is stopped. This is the default Sequencer mode.
●
Channel-defined Sequence
First, a single sequence is performed. Then, only "Channel"s in continuous sweep
mode are repeated continuously.
