Freq Resp Above 3 GHz Preamp On Adjustment

This adjustment applies to the following models:

This adjustment procedure performs the following steps (for Options P07, P13, and P26):

The analyzer's internal flatness corrections are turned off. The Preamp is turned on and 10 dB of RF attenuation is set (this is the reference state). Amplitude error is measured as a function of frequency from 13.6 GHz (Opt. P13) or 26.5 GHz (Opt. P26). The measured error is normalized to 50 MHz and the error is stored in the analyzer memory as frequency/amplitude pairs.

The related performance test for this adjustment is Frequency Response Above 3 GHz (Preamp On).
