This adjustment is used to calibrate the internal diagnostics measuring
ADC.
This adjustment is used to determine the optimal power out of the A7A2
20 GHz Frequency Multiplier. If the power is too low, it will impact the
ability of the system to deliver enough output power. If the power is too
high, it will increase the harmonic content of the output.
This adjustment is used to linearize the ALC detector for the best power
accuracy.
This adjustment measures the absolute power at the mid-point of the ALC
vernier and generates a cross calibration file for the ALC calibration and
attenuator calibration. This adjustment also calibrates the first two
attenuator steps (bypass, 0 dB and 5 dB), covering the frequency range of
9 kHz to 50 MHz.
