The RF Amp Diagnostic reads the board level information from RF Amp.

This document describes the theory of each test in RF Amplifier Diagnostics.

This diagnostic provides self-test functions of internal amplifier circuitry. This self-test is performed on a measurement function of PSU +48V Voltage Measurement Circuit. The test signal that is input from the amplifier to control board is replaced by a test voltage that is generated by circuitry on the control board under software control. For Measurement Circuit Test, the diagnostic will inject a test voltage into the measurement circuit, cause an analog to digital conversion to occur, and read and compare the conversion results to an expected value.
