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

directly  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  insure  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  mod-ulation  (peak
deviation) to 25 kHz with the audio modulation
adjustment.    A  known  off-air  signal  and  a  TV
may be used to set adjust-ment for equal audio
level.

7.

Connect  the  "RF 

OUTPUT"

  to  a  proper

combining network.

T

he  Federal  Communications  Commission

requires  that  cable  system  modulators  which
operate  in  the  aircraft  communications  and
navigation bands be offset 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 beat products.  The technique is used in expensive phase-locked headends where all
units are tied to a master 6.0003 MHz oscillator with a maximum error of 1 Hz.
