Preamp (Option P03)
a
a. The preamp follows the input attenuator, AC/DC coupling switch, and precedes the input mixer. In
low-band, it follows the 3.6 GHz low-pass filter.

b. Preamp Gain directly affects distortion and noise performance, but it also affects the range of levels that
are free of final IF overload. The user interface has a designed relationship between input attenuation
and reference level to prevent on-screen signal levels from causing final IF overloads. That design is
based on the maximum preamp gains shown. Actual preamp gains are modestly lower, by up to nomi-
nally 5 dB for frequencies from 100 kHz to 3.6 GHz.
