IF Frequency Response Adjustment

This adjustment applies to the following models with firmware below A.09.00:

All adjustments will require the CFG Option. Refer to the CFG Option section for more information.

The SA calibration consists of five different adjustments that should be performed in succession in the following order. For more information, click here.Closed

  1. LO Feedthru

  2. Absolute Amplitude

  3. Frequency Response

  4. Attenuator Slope

  5. IF Frequency Response

This procedure characterizes the hardware IF filter and stores the characterization information in the FieldFox. A characterization is performed for each SA band. The characterization information is used to improve measurement accuracy when post-processing the raw measurement data.
