2 Welcome to the Spectrum application
The R&S ZNL "Spectrum" application is a firmware application that adds functionality
to perform spectrum analysis to the R&S ZNL.
Availability of the "Spectrum" application
The "Spectrum" application becomes available when you equip the R&S ZNLxx with
the optional spectrum analyzer hardware option R&S ZNLxx-B1.
This hardware option is not available for the R&S ZNLE and for R&S ZNL14 and
R&S ZNL20 with serial numbers below 101200.
This user manual contains a description of the functionality that the application pro-
vides, including remote control operation.
All functions not discussed in this manual are the same as in the base unit and are
described in the R&S ZNL User Manual. The latest version is available for download at
the product homepage http://www.rohde-schwarz.com/product/ZNL.
2.1 Starting the Spectrum application
"Spectrum" is an application on the R&S ZNL.
To activate the "Spectrum" application
1. Select the [MODE] key.
A dialog box opens that contains all applications currently available on your
R&S ZNL.
2. Select the "Spectrum" item.
The R&S ZNL opens a new channel setup for the "Spectrum" application.
For details see Chapter 3.1, "Available applications", on page 20
The measurement is started immediately with the default settings.

2.2.1 Channel Setup bar
Using the R&S ZNL you can handle several different measurement tasks (channel set-
ups) at the same time (although they can only be performed asynchronously). For each
channel setup, a separate tab is displayed on the screen. To switch from one channel
setup to another, simply select the corresponding tab.
Understanding the display information - Spectrum application
Welcome to the Spectrum application
R&S®ZNL
9User Manual 1178.5972.02 ─ 17
If many tabs are displayed, select the tab selection list icon at the right end of the chan-
nel setup bar. Select the channel setup you want to switch to from the list.
MultiView tab
If more than one channel setup is active, an additional tab labeled "MultiView" provides
an overview of all active channel setups at a glance. In the "MultiView" tab, each indi-
vidual window contains its own channel setup bar with an additional button. Tap this
button, or double-tap in any window, to switch to the corresponding channel setup
quickly.
Icons in the channel setup bar
The yellow star icon on the tab label (sometimes referred to as a "dirty flag") indi-
cates that invalid or inconsistent data is displayed, that is: the trace no longer matches
the displayed instrument settings. This can 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 disap-
pears.
The icon indicates that an error or warning is available for that channel setup. This is
particularly useful if the MultiView tab is displayed.
The icon indicates the currently active channel setup during an automatic measure-
ment sequence (Sequencer functionality).

channel setup specific setting
Beneath the channel setup name, information on specific settings for the measurement
is displayed in the channel setup bar. Channel Setup information varies depending on
the active application.
In the "Spectrum" application, the R&S ZNL shows the following settings:
Table 2-1: Channel Setup settings displayed in the channel setup bar in the Spectrum application
Ref Level Reference level
Att RF attenuation that has been set.
Ref Offset Reference level offset
SWT Sweep time that has been set.
If the sweep time does not correspond to the value for automatic coupling,
a bullet is displayed in front of the field. The color of the bullet turns red if
the sweep time is set below the value for automatic coupling. In addition,
the UNCAL flag is shown. In this case, the sweep time must be increased.
For FFT sweeps, an estimated duration for data capture and processing is
indicated behind the sweep time in the channel setup bar.
Meas Time/AQT Measurement (acquisition) time, calculated from analysis bandwidth and
number of samples (for statistics measurements)
RBW Resolution bandwidth that has been set.
If the bandwidth does not correspond to the value for automatic coupling,
a green bullet appears in front of the field.
VBW Video bandwidth that has been set.
If the bandwidth does not correspond to the value for automatic coupling,
a green bullet is displayed in front of the field.
AnBW Analysis bandwidth (for statistics measurements)
Compatible Compatible device mode (FSV, default; default not displayed)
Mode Indicates which sweep mode type is selected:
"Auto FFT": automatically selected FFT sweep mode
"Auto sweep": automatically selected swept sweep mode
"Sweep": manually selected frequency sweep mode
"FFT": manually selected FFT sweep mode
Icons for individual settings
A bullet next to the setting indicates that user-defined settings are used, not automatic
settings. A green bullet indicates this setting is valid and the measurement is correct. A
red bullet indicates an invalid setting that does not provide useful results.
Common settings
The channel setup bar above the diagram not only displays the channel setup-specific
settings. It also displays information on instrument settings that affect the measure-
ment results even though it is not immediately apparent from the display of the mea-
sured values. This information is displayed in gray font and only when applicable for
the current measurement, as opposed to the channel setup-specific settings that are
always displayed.

2.3 Configuring result displays
Measurement results can be evaluated in many different ways, for example graphically,
as summary tables, statistical evaluations etc. Thus, the result display is highly config-
urable to suit your specific requirements and optimize analysis. Here you can find out
how to optimize the display for your measurement results.

2.3.1 Laying out the result display with the smartgrid
In NWA mode, the R&S ZNL does not provide different result windows. Thus, the
SmartGrid functionality is only available in the (optional) Spectrum mode.
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 setup tab. Up to 16 individual windows can be dis-
played per channel setup (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 Chapter 6.2.2, "Basic evaluation methods",
on page 98.)
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, pos-
sibly changing the layout of the other windows, as well.
All evaluation methods available for the currently selected measurement are dis-
played 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 eval-
uation icon in relation to the existing windows.
All display configuration actions are only possible in SmartGrid mode. When Smart-
Grid mode is activated, the evaluation bar replaces the current softkey menu dis-
play. When the SmartGrid mode is deactivated again, the previous softkey menu
display is restored.

2.3.1.1 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 2-1: 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 win-
dow 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 2-2). If an existing win-
dow 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).

SmartGrid functions
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 remain-
ing windows.
2.3.1.2 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 Smart-
Grid 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.
To close the SmartGrid mode and restore the previous softkey menu select the "Close"
icon in the right-hand corner of the toolbar, or press any key.

3 Operating modes, applications, channel set-
ups, and result displays
If the spectrum analysis hardware option R&S ZNLxx-B1 is installed, the R&S ZNL is
actually two instruments in one: a vector network analyzer (VNA) and a spectrum ana-
lyzer (SA). The R&S ZNL integrates the functionality of the two as separate operating
modes in one instrument. The advantage is that you can perform typical network ana-
lyzer tasks on a dedicated network analyzer, and spectrum analyzer tasks on a dedica-
ted spectrum analyzer, without having to buy, maintain, and set up two individual
instruments. Furthermore, you can easily and quickly switch between measurement
tasks in different operating modes, and hardly notice the difference in operation. Both
are just different applications on the same instrument. Internally, however, the data is
processed using entirely separate hardware, always optimized to the selected operat-
ing mode.
A spectrum analysis" hardware option is not available for the R&S ZNLE and for
R&S ZNL14 and R&S ZNL20 with serial numbers below 101200.
Note that interruptions in analog output may occur if you switch between a VNA
and a spectrum application, due to the separate hardware. In particular, if you run a
sequence of measurements including both measurement types, switching between
both modes can interrupt the signal from the output connector.
The Spectrum operating mode allows you to perform all sorts of different analysis tasks
on different types of signals, e.g. Analog Demodulation, I/Q analysis or basic spectrum
analysis. Depending on the task or type of signal, a different set of measurement func-
tions and parameters are required. Therefore, the Spectrum operating mode provides
various applications - some of which are included in the base unit, others are optional.
The default application when you start the R&S ZNL is "VNA", for basic network analy-

When you activate an application, a new channel setup is created which determines
the measurement settings for that application. The same application can be activated
with different measurement settings by creating several channel setups for the same
application.
The number of channel setups that can be configured at the same time depends on the
available memory on the instrument.
For more information on creating channel setups, see Chapter 3.3, "Defining channel
setups", on page 22.

3.1 Available applications
Access: [Mode]
Without the spectrum analysis hardware option R&S ZNLxx-B1, the R&S ZNLxx only
provides the VNA application.
The "Spectrum analysis" hardware option adds the Spectrum and I/Q Analyzer
applications.
The "Analog Demodulation" software option R&S FPL1-K7 adds the Analog
Demod application.
The "Noise Figure" software option R&S FPL1-K30 adds theNoise Figure applica-
tion.
Each application is described in a separate manual.
For the R&S ZNLE and for R&S ZNL14 and R&S ZNL20 with serial numbers below
101200, these options are not available and hence there is only the VNA application.

VNA
In the VNA application the provided functions correspond to those of a conventional
vector network analyzer.
Remote command:
INST:SEL VNA, see INSTrument[:SELect] on page 408
Spectrum
In the "Spectrum" application the provided functions correspond to those of a conven-
tional spectrum analyzer. The analyzer measures the frequency spectrum of the RF
input signal over the selected frequency range with the selected resolution and sweep
time. Alternatively, it displays the waveform of the video signal for a fixed frequency.
The "Spectrum" application requires a R&S ZNLxx equipped with the spectrum analy-
sis hardware option R&S ZNLxx-B1.
Note: For the R&S ZNLE and for R&S ZNL14 and R&S ZNL20 with serial numbers
below 101200, a spectrum analysis hardware option is not available.
The "Spectrum" application is described in the R&S ZNL Spectrum Analyzer Mode
User Manual.
Remote command:
INST:SEL SAN, see INSTrument[:SELect] on page 408
I/Q Analyzer
The I/Q Analyzer application provides measurement and display functions for I/Q data.
