2 Getting Started
This section explains the basic operation of the Handheld Spectrum Analyzer R&S FSH using some
simple measurements as examples. A more detailed description of operation and functions, such as
selecting menus and setting measurement parameters, is provided in section 3 of this manual.
Measurements on CW
Signals
A basic task performed by spectrum analyzers is measuring the level and frequency of sinewave
signals. The following examples illustrate the most effective way of performing these measurements
with the R&S FSH.
A signal generator is used as a signal source, e.g. the Signal Generator R&S SML.
Measurement setup:
Connect the RF output of the signal generator to the RF input of the R&S FSH.
Signal generator settings:
Frequency 100
MHz
Level
-30
dBm
Level measurement
First, set the R&S FSH to its default settings to show all the operating steps that are required.
Press the PRESET key.
The analyzer displays the frequency spectrum from
100 kHz to 3 GHz or 100 kHz to 6 GHz (dependent on
the model) – the R&S FSH’s maximum frequency
span. At 100 MHz, the generator signal is displayed as
a vertical line. Generator harmonics can also be seen
as lines at frequencies that are multiples of 100 MHz.
To analyze the generator signal at 100 MHz in more
detail, reduce the frequency span. Set the R&S FSH’s
center frequency to 100 MHz and reduce the span to
10 MHz.
