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 given in section 3 of the manual on
the CD-ROM.
3.1 Controlling the RF Attenuator
Depending on the selected reference level, the
R&S FSH sets the attenuator on the RF input to
a suitable value. It offers two modes: one for the
highest possible sensitivity (AUTO LOW NOISE)
and one for the lowest possible intermodulation
products (AUTO LOW DISTORTION). The difference
between the two modes is that the attenuation that
the R&S FSH sets for the RF attenuator is 5 to 10 dB
higher for AUTO LOW DISTORTION than for AUTO
LOW NOISE. The default setting is AUTO LOW
DISTORTION. The table in the chapter on working
with a pre-amplifi er shows the setting for the RF
attenuator as a function of the reference level.
 Press the AMPT key.
 Press the RF ATT/AMP/IMP softkey.
 Select the desired AUTO LOW NOISE or AUTO
LOW DISTORTION mode with the rotary knob
or the cursor keys below the RF ATTENUATION
menu item.
