The Horizontal UDC / Transmitter Control (Unit 2 A1 A3 A2 A2) is essentially identical to the Vertical UDC /
Transmitter Control (Unit 2 A1 A3 A2 A3) and the procedures for Troubleshooting, Maintenance, and
Calibration and Alignment are identical. The only exception is the Signal Generator (Unit 2 A1 A3 A2 A2 A6)
and the Frequency Multiplier (Unit 2 A1 A3 A2 A2 A5), which mounts on the Horizontal Assembly ONLY.
When troubleshooting the Vertical Assembly, the aforementioned subcomponents in the Horizontal Assembly
will remain a part of the Troubleshooting Procedures.
The UDC/Transmitter Control Unit controls the power, communication, and signal for all
components in the Transceiver Assembly. Use the following procedures to troubleshoot the
Horizontal Transmitter.
1. Step 1 (Power):
Check the power per Paragraph 2.1.3.2.
Check the Status Lights on the Transceiver Power Supply.
Is the power output correct? Are the status lights properly lighted?
YES: Continue to Step 2
NO: Replace the Transceiver Power Supply and restart the troubleshooting steps.
