2 Welcome to the I/Q Analyzer Application
The R&S FSWP I/Q Analyzer is a firmware application that adds functionality to per-
form I/Q data acquisition and analysis to the R&S FSWP.
The R&S FSWP I/Q Analyzer features:
●Acquisition of analog I/Q data
●Import of stored I/Q data from other applications
●Spectrum, magnitude, I/Q vector and separate I and Q component analysis of any
I/Q data on the instrument
●Export of I/Q data to other applications
Availability of the I/Q Analyzer and Spectrum Monitor
The full I/Q Analyzer becomes available when you equip the R&S FSWP with the
optional Spectrum Analyzer hardware (R&S FSWP-B1).
You can still analyze I/Q data without this hardware option in the Spectrum Monitor
application.
It runs on the phase noise analyzer hardware and is available for free with firmware
version 1.60.
Compared to the full I/Q analyzer, which runs on the optional spectrum analyzer hard-
ware, it has the following characteristics and limitations.
●When you open a spectrum monitor, the frequency, level and input parameters are
initially adopted from the phase noise application (you can change them in the
spectrum monitor, of course).
Those settings are the same as in the full I/Q analyzer.
●Maximum analysis bandwidth of 20 MHz and sample rate of 25 MHz (and no sup-
port of bandwidth extensions).
●Advanced data acquisition settings are unavailable.
●I/Q data import and export are the same as in the full I/Q analyzer.
●Spectrograms, general marker functionality, marker functions and limit lines are the
same as in the full I/Q analyzer.
●Only external triggers are supported.
●Only evaluation of the frequency spectrum is supported.
●Trace mathematics are not available.
All other functionality is the same as that of the I/Q analyzer.
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 FSWP User Manual. The latest version is available for download
at the product homepage http://www.rohde-schwarz.com/product/fswp.

Additional information
Several application notes discussing I/Q analysis are available from the Rohde &
Schwarz website:
1EF85: Converting R&S I/Q data files
1EF92: Wideband Signal Analysis
1MA257: Wideband mm-Wave Signal Generation and Analysis
1EF84: Differential measurements with Spectrum Analyzers and Probes
Installation
The R&S FSWP I/Q Analyzer application is part of the optional Spectrum application
and requires no further installation.
2.1 Starting the I/Q Analyzer Application
The I/Q Analyzer is an application on the R&S FSWP.
To activate the I/Q Analyzer application
1. Select the [MODE] key.
A dialog box opens that contains all applications currently available on your
R&S FSWP.
2. Select the "I/Q Analyzer" item.
The R&S FSWP opens a new channel for the I/Q Analyzer application.
The measurement is started immediately with the default settings.
It can be configured in the I/Q Analyzer "Overview" dialog box, which is displayed
when you select the "Overview" softkey from any menu (see Chapter 5, "Configura-
tion", on page 36).
Multiple Channels and Sequencer Function
When you activate an application, a new channel is created which determines the
measurement settings for that application (channel). The same application can be acti-
vated with different measurement settings by creating several channels for the same
application.
The number of channels that can be configured at the same time depends on the avail-
able memory on the instrument.
