5.1 Using the Spectrum Analyzer
This chapter provides a short overview of the first steps of the measurements you
can perform with the R&S Spectrum Rider.
5.1.1 Attenuating the Signal
You can attenuate the signal to a suitable level either manually or automatically.
In case of automatic attenuation, the level of attenuation at the RF input depends
on the current reference level. The R&S Spectrum Rider provides two ways of
automatic attenuation.
For the highest possible sensitivity, it provides the "Auto Low Noise" attenuation
mode. For the lowest possible intermodulation, it provides the "Auto Low Distor-
tion" mode.
The main difference between the two modes is that the attenuation level is 5 dB
to 10 dB higher in case of "Auto Low Distortion" than it is for "Auto Low Noise". In
the default state, "Auto Low Distortion" is active.
1. Press [AMPT] key.
2. Select "Att/Amp/Imp" softkey.
3. Select either the "Auto Low Noise" or "Auto Low Distortion" menu item.
The R&S Spectrum Rider shows the current attenuation level in the "Parame-
ter view". The currently active menu item has a blue background and the
selected parameters is indicated with a blue dot in the menu item.
