Installation Procedures

Adherence to these precautions will help prevent problems during

initial installation of the PFAM 550SUB.

1.Connect the I.F. jumper from the I.F. output to the I.F. input on the rear panel.

2.Connect the PFAM 550SUB to a 115 VAC ground- ed receptacle. Observe the lit LED light indicating power is on.

3.Using a signal level meter or spectrum analyzer, set the output level.

4.Check the aural carrier level. It should be set at 15 dBmV below the video carrier.

.

WARNING: When connecting the PFAM 550SUB di- rectly to a TV set, attenuate the output sufficiently to prevent overdriving the TV. The front panel test point is useful for monitoring modulator output.

5.Connect a 1.0 volt peak-to-peak video source to the “VIDEO IN” on rear panel. Connect the “RF OUT” to a TV set, and compare the contrast and brightness to a known signal (use off-air signal to ensure a proper modulation level). If necessary, adjust the video modulation until proper contrast is observed.

6.Connect an audio source to the “AUDIO IN” on rear of the unit. Set audio modulation (peak deviation) to

25 kHz with the audio modulation adjustment. A known off-air signal and a TV may be used to set adjustment for equal audio level.

7.Connect the “RF OUTPUT” to a proper combining network.

FREQUENCY OFFSETS

The Federal Communications Commission requires that cable system modulators which operate in the aircraft communications and navigation bands be off- set in frequency by 12.5 kHz. The PFAM 550SUB PLL

oscillator is factory set to comply with FCC requirements for frequency accuracy (+/- 5 kHz) in the aeronautical communication and navigation bands.

Harmonically Related Coherent (HRC) video carriers and Incrementally Related Coherent (IRC) video carriers are CATV channel assignment methods to reduce the effect of intermodulation products. The technique is used in ex- pensive phase-locked headends where all units are tied to a master 6.0003 MHz oscillator with a maximum error of 1 Hz.
