Nominal frequency: (Channel frequency - 7.5kHz) ±0.002%
Repeat the measurements for Clearance Tx2.
Record the frequency readings in Table 6-11.
6.4.2 LF Frequency check.
90/150 Hz MODULATION FREQUENCY checks
Switch on Course Tx1.
• Connect the Frequency Counter to CSB test connector on Course Tx1 Section via a 50
ohm test cable. (Use high impedance input port of counter)
• Turn off the 90 Hz modulation for Course Tx1 through the Local Display and Keyboard or
the RMM Program.
• Read the 150 Hz frequency. Tolerance ±0.05 Hz.
• Turn the 90 Hz modulation on and turn 150 Hz modulation off through the Local Display
and Keyboard or the RMM Program.
• Read the 90 Hz frequency. Tolerance ±0.05 Hz.
Repeat the test for Course Tx2.
Record the frequency readings in Table 6-12.
6.4.3 Transmitter waveforms checks.
Carry out the tests outlined in paragraphs a)...f) for Cou Tx2, CLR Tx1 and CLR Tx2.
Record the results of the outlined tests in Table 6-8.
6.4.3.1 PHASE CORR. check.
Switch on Course Tx1.
• Connect the Oscilloscope to PHASE CORR test connector on Course Tx1 Section via a 50
ohm test cable.
• Set Oscilloscope input mode to DC.
The waveform observed should take a continuous form without limiting segments or deep
notches or other discontinuities.
(Each modulator develops it's own waveform shape due to spreads in insertion phases).
The dynamic maximum point should be approximately -4 volt.
6.4.3.2 SBO waveform checks.
Switch on Course Tx1.
• Connect the Oscilloscope to SBO test connector on Course Tx1 Section via 50 ohm test
cable.
• Set Oscilloscope input mode to DC.
• Check that the waveform resembles the graph below, left.
For best signal resolution on the scope, it is advisable to set the oscilloscope in double sweep
rate and FREE RUN trigger mode ("kissing pattern" mode). The two halves of the 30 Hz wave-
form will then overlap and look like one waveform when perfect power balance is achieved.
