No beam on Xevo TQ-S due to short on the StepWave - WKB30214

Article number: 30214

SYMPTOMS

  • Increasing the Diff Ap 2 to 30 increases the beam significantly
  • Checking the StepWave diagnostics shows that the T-Wave 2 RF Amplitude and RF current are reading back incorrectly
  • Unplugging the TW2 D-type from the enhanced source transfer PCB shows the correct T-Wave 2 RF Amplitude and RF current readback; this indicates that the board is ok but there is a short downstream from the board

ENVIRONMENT

  • Xevo TQ-S

CAUSE

Short on StepWave

FIX or WORKAROUND

Clean or replace the StepWave (700011117).
