Freq Resp Above 3.6 GHz Preamp On Adjustment

This adjustment applies to the following models equipped with Preamplifier:

This adjustment procedure performs the following steps (for Options P07, P08, P13, P26, P43,P44, and P50):

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 3.6 GHz to 50 GHz depending on the preamp option. The measured error is normalized to 4800 MHz and the error is stored in the analyzer memory as frequency/amplitude pairs.
