Aux IF Out
This menu controls the signals that appear on the SMA output on the rear panel labeled "AUX IF OUT
The Aux IF Out functionality is only valid for RF and External Mixer inputs.
NOTE
When using the External Mixing path, the Aux IF Out levels (for all three Options
CR3, CRP, and ALV) will be uncalibrated because the factory default Aux IF level
was set to accommodate the expected IF levels for the RF path.

In the PSA, the IF output has functionality equivalent to the "Second IF"
function in the X-Series' Aux IF Out menu. In the X-Series, it is necessary to
switch the Aux IF Out to "Second IF" to get this functionality, whereas in
PSA it is always on, since there are no other choices. Hence a command to
switch this function to "Second IF" will have to be added by customers
migrating from PSA who use the IF Output in PSA.
