4.4.3 RF Preamp
Control the state of the internal preamplifier (PA) located in the RF input signal path. When the
signal-under-measurement is small, turning on the preamplifier can reduce the displayed average
noise level to aid distinguishing small signals from the noise.
The corresponding icon “ PA ” will appear at the left side of the screen when the preamplifier is
turned on.

when the scale type is set to “ log ”.
⚫ By changing the scale, the displayed amplitude range is adjusted.
⚫ Current signal amplitude range that can be displayed:
The Minimum range: Reference level –10 × current scale value.
The Maximum range: The reference level.
