1 General Information
The Rohde & Schwarz FS-K40 application extends the functionality of the R&S FSP,
R&S FSU and R&S FSQ spectrum analyzers to enable phase noise measurements.
This manual supports the user in working with R&S FS-K40. It aids the preparation,
execution and evaluation of a measurement and gives many helpful hints and examples.
For the user wanting to make a quick start to using R&S FS-K40, the Quick Start Guide
section below works step-by-step through an ordinary phase noise measurement. The
remainder of this section describes all of the basic information about how the R&S FS-K40
application works, without covering phase noise measurements in detail. A detailed
description of all measurement modes, settings and results can be found in section 2.
Section 3 covers remote control operation of R&S FS-K40.

1.1 Introduction to R&S FS-K40 & Phase Noise
Measurements
Phase Noise Measurement Software R&S FS-K40 extends the measurement capabilities
of Rohde&Schwarz spectrum analyzers to give a phase noise tester. The R&S FSP, R&S
FSU & R&S FSQ are ideal for this purpose because of their low inherent phase noise and
noise figure. The high phase noise measurement speed is achieved through the high sweep
rates of all analyzers. It is possible to trade off speed against accuracy at small resolution
bandwidths (M1 kHz) by using either FFT or digital filters. The software allows different
settings within a phase noise diagram, e.g. FFT close to the carrier and analog/digital filters
far off the carrier.
1.2 Installation
From the analyzer select firmware update.
1. Press the SETUP hardkey followed by NEXT, FIRMWARE UPDATE and finally the
FIRMWARE UPDATE softkey. Following the instructions displayed.
Once the installation has completed the analyzer will reboot.
Once the option has been installed it needs to be activated:
