Absolute Amplitude Adjustment

This test 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 adjustment generates an amplitude correction at the reference frequency (50 MHz) for every attenuator level (0-30 db attenuator, every 5 dB step).
