About External Mixers (Input)

The External Mixer tab in the Input dialog is used to configure an external mixer attached to the LO/IF port of an X-Series Signal Analyzer.

Here is a list of the properties shown in the External Mixer tab:

Mixer Selection
Harmonic Table
Cable IF Loss
Bias
Mixer Paths
Aux IF Frequency
USB Mixer status
Input Attenuation
Cable Correction

The External Mixer tab is modeled after the external mixer settings in the X-Series Analyzer. For more information, see the help for the external mixer topics located in the Input/Output > External Mixer section in the X-Series Help.

Amplitude Corrections

To correct for amplitude variations of the external mixer, you can use the corrections defined in the X-Series Analyzer by setting the Instrument User Corrections parameter to On or by defining an RF Filter with User Corrections.

The amplitude corrections supplied by the smart mixer to the X-Series Analyzer will be applied to the time data sent to the VSA.
