notice This diagnostics may fail if multiple iteration numbers are set even though there is no problem in SRFD3. If this issue occurred, perform the following. Perform TPS reset. pen RF Amplifier Diagnostics menu and set Iteration Number to '1' . Run RF Amplifier Diagnostics. If the fail is occurred, perform TPS reset and perform same diagnostics again (step1 ~ step3). If the same fail is occurred, perform troubleshooting. The problem may exist in CAN communication between CAM Lite2 and SRFD3 or SRFD3 itself.

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 an overload detection function of Peak Forward Power Overload 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 Overload Circuit Test, the trip point for detecting the overload is temporary adjusted below the level of the inject test input voltage in order to verify the functionality of the circuit.

This diagnostic provides self-test functions of internal amplifier circuitry. This self-test is performed on a measurement function of Peak Forward Power 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.
