Description

Full Scale (ADC Clipping)

Default settings, signal at CF

Band 0
Band 1 through 4
High Gain setting, signal at CF
(IF Gain = High)
Band 0
Band 1 through 4
Effect of signal frequency
a.
This table is meant to help predict the full-scale level, defined as the signal level for which ADC overload (clipping)
occurs. The prediction is imperfect, but can serve as a starting point for finding that level experimentally. A SCPI
command is also available for that purpose.
b.
Mixer level is signal level minus input attenuation.
c.
The available gain to reach the predicted mixer level will vary with center frequency. Combinations of high gains and
high frequencies will not achieve the gain required, increasing the full scale level.
