2 Purpose

Notice Image
  • 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.
    • Open 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 MGD and SRFD3 or SRFD3 itself.

This document describes the theory of each test in RF Amplifier Diagnostics - PSU Voltage Test.

3 PSU +15 Voltage Test

This diagnostic tests the auxiliary PSU voltage (+15 Volts) of internal amplifier.

4 PSU -15 Voltage Test

This diagnostic tests the auxiliary PSU voltage (-15 Volts) of internal amplifier.

5 PSU +48 Voltage Test

This diagnostic tests the auxiliary PSU voltage (+48 Volts) of internal amplifier.

6 PSU High Voltage Test

This diagnostic tests the auxiliary PSU voltage (High Voltage; +160 Volts) of internal amplifier.
