OUT
NOTE
Aux IF Out is valid for the RF Input and for the External Mixer input. In external
mixing, the Aux IF output level is set by factory default to accommodate expected
IF levels for the RF path. When using the External Mixing path, the Aux IF Out
levels (for all three options CR3, CRP and ALV) will therefore be uncalibrated.

Notes
In PSA, the IF output had functionality equivalent to the SIF option in X-Series’ Aux IF Out menu. In X-
Series, it is necessary to switch Aux IF Out to SIF to get this functionality, whereas in PSA it is always
on, since there are no other choices
Hence, if you are migrating remote code from PSA, and you use the IF Output in PSA, you will need to
add a command to switch this function to SIF
Option Details
The Aux IF Output options are:
Source SCPI Notes
Off
OFF
No signal is output from the AUX IF OUT connector on the rear panel
The connector appears as an open-circuit (that is, it is not terminated in any way)
Second IF
SIF
The 2
nd
IF output is routed to the rear panel connector. Annotation on the menu panel
shows the current 2
nd
IF frequency in use in the instrument
Arbitrary IF
AIF
The 2
nd
IF output is mixed with a local oscillator and mixer to produce an arbitrary IF
output between 10 MHz and 75 MHz with 500 kHz resolution. The phase noise in this
mode will not be as good as in Second IF mode
The IF output frequency is adjustable, through an active function which appears on the
menu panel, from 10 MHz to 75 MHz with 500 kHz resolution
Note that, in instruments with Options B2X or B5X, the Arbitrary IF Output is only
