2.4 Using the Spectrum Analyzer (Option R&S ZVH-K1)
Equipped with option R&S ZVH-K1 (order no. 1309.6823.02), the R&S ZVH is able to
perform spectrum measurements.
► Press the MODE key.
► Press the "Spectrum Analyzer" softkey.
The R&S ZVH turns on spectrum analyzer mode.
2.4.1 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 ZVH 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 Distortion" mode.
The main difference between the two modes is that the attenuation level is 5 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.
► Press the SCALE/AMPT key.
► Press the "RF Att/Amp/Imp" softkey.
► Select either the "Auto Low Noise" or "Auto Low Distortion" menu item.
The R&S ZVH shows the current attenuation level in the hardware settings
overview ("Att.:" caption). The currently active menu item has a green background.
