gain of the amplifier is in the range from 15 dB to 20 dB and increases the sensi-
tivity by 10 dB to 15 dB.
In the signal path, the preamplifier comes after the input protection circuit and
before the RF attenuator of the R&S Spectrum Rider to provide excellent sensitiv-
ity when the preamplifier is switched on.
1. Press [AMPT] key.
2. Select "Att/Amp/Imp" softkey.
3. Enable or disable the "Preamp" checkbox to turn on or off the preamplifier of
the R&S Spectrum Rider.
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.

Measuring CW Signals
A basic task for spectrum analyzers is to measure the level and frequency of sin-
ewave signals. The following examples illustrate an effective way of performing
these measurements.
A signal generator, e.g. R&S SMBV provides the signal source.
