2.4.2 Using the Preamplifier
The R&S ZVH has an internal preamplifier to increase sensitivity. Depending on the
frequency, the gain of the amplifier is in the range from 15 to 20 dB and increases the
sensitivity by 10 to 15 dB.
In the signal path, the preamplifier comes after the RF attenuator and before the input
mixer.
► Press the SCALE/AMPT key.
► Press the "RF Att/Amp/Imp" softkey.
► Select either the "Preamp On" or "Preamp Off" menu item.
The R&S ZVH turns the preamplifier on or off.
The magnitude of amplification depends on the reference level. This coupling to the
reference level makes sure that the dynamic range is at an optimum.
