Trigger 4A Description
Sequence: All
Trigger 4A (Quiet Test: LP Biasing effect on CAPS)
This mode is designed to step through a series of bias voltage values for
the LP and allow the other instruments to check for interference.

Bands ABC require 2.945 sec to complete, H1 requires 26.457 sec, and
H2 requires 20.365 sec for a total of 49.767 sec per sweep. The hfr
cycle time is 51.000 seconds.
