Table 5-14.Error Message 114

Down Converter

Error 114 Down Converter LO not Locked

Description: The local oscillator in the down converter assembly is not phase-locked.

Step 1. Disconnect cable W112 at A3J2.

Step 2. Using a spectrum analyzer, verify the presence of a +5 dBm ￿6 dB, 500 MHz signal at A3J2.

qIf present, go to step 3.

If not present, replace the A3 PCB.

Step 3. Reconnect cable W112 to A3J1, then disconnect cable W112 at J2 of the down converter assembly.

Step 4. Using a spectrum analyzer, verify the presence of a +5 dBm ￿6 dB, 500 MHz signal at the end of cable W112.

qIf present, replace the down converter assembly. If not present, replace cable W112.
