Verifying Transmitter Circuitry Procedure

Procedure:

1 Connect and set up test equipment as shown in Figure 37: Test Equipment Setup for Verifying

Transmitter Circuitry on page 85.

2 Apply input power (AC or DC) to the repeater. The power supply, modem, and PA fans should

run a few seconds to confirm fan operation.

3 Press the PTT switch of the microphone and observe the PA Keyed LED indicator on the

Repeater Front Panel.

If PA Keyed fails to light, suspect the following:

• Faulty Power Amplifier Module

• Faulty Modem Module

• Loose or bad Exciter-to-PA RF cable

• Loose or bad PA-to-antenna RF output cable

• Improperly terminated PA RF output cable

• Faulty Power Supply Module

4 Measure output power by pressing the PTT button and observing reading on an in-line

wattmeter.

• If PA output is not at proper power (as set for particular site), adjust the output power as

described in the CPS online help.

5 If PA output power is proper, set up the Service Monitor for spectrum analyzer display. Press the

PTT button and observe the display. The display should show a single frequency carrier:

• If the display shows multiple carriers evenly spaced about the carrier, suspect a faulty Exciter

module or PA module.

• If the display shows a solid carrier but it is off frequency, suspect the following:

• Faulty Modem Module

• Faulty external 5/10 MHz reference source (if used)

• If the display shows a single carrier moving erratically, suspect a faulty Modem Module.

6 If display is proper, set up Aeroflex 3900 Series Communications System Analyzer to display

modulation. Using the microphone, push the PTT button and speak into the microphone. Verify

that the display shows an audio signal.

• If the proper display is not obtained, suspect faulty SCM or Exciter Module

7 Set the Aeroflex 3900 Series Communications System Analyzer for GEN/MON MTR. Press the

PTT button and speak loudly into the microphone to cause maximum deviation. Display should

read:

• 4.60 kHz maximum for a 25 kHz system

• 3.68 kHz maximum for a 20 kHz system

• 2.30 kHz maximum for a 12.5 kHz system

If the proper display is not obtained, suspect faulty SCM or Exciter Module.

8 This completes the Verifying Transmitter Circuitry test procedure. If all displays and

measurements are correct, the transmitter circuitry may be considered to be operating properly.
