23.
Move signal generator to the LINE RCV PORT 1 jack (Jl). Do not
readjust any receive level controls. Move the 600-ohm terminated
dB level meter to the COMBINED DIST OUTPUT jack (J9).
24.
Read -10 dBm.
25.
Move the 600-ohm terminated dB level meter to the LINE XMT
PORT 4 jack (J8).
26.
Read system line transmit test tone level -16 dBm for port 4. Ad-
just the LINE XMT PORT 4 level control (R62) for proper reading.
27.
Calibration for the 44118 is now complete. Remove the signal gen-
erator and dB meter.
28.
Remove the 46105 and the 44022 if they are not already removed.
29.
Insert a 1 KHz Tone at a +7 dBm level into port 1 RCV port and
verify that the tone can be seen at C1 Pins 31 and 6, Pins 33 and 8,
Pins 29 and 4, and at B Pins 5 and 6. Level meter should be termi-
nated and it should read -16 dBm.
30.
Move the 1 KHz tone to Port 3 RCV input and verify that the tone
can be seen at C1 Pins 27 and 2 at a -16 dBm level.
31.
Connect the level meter (terminated) to the summing distribution
port. Set the oscillator for a 1 KHz tone at a +7 dBm level and
connect it to B 3 andB 4, observe the level meter, it should read
-10 dBm.
32.
Move the oscillator to C1 Pins 28 and 3 and observe the level meter
for a -10 dBm reading
33.
Move the oscillator to C1 Pins 32 and 7 and observe the level meter
for a -10 dBm reading
34.
Move the oscillator to C1 Pins 26 and 1 and observe the level meter
for a -10 dBm reading
35.
Move the oscillator to C1 Pins 30 and 5 and observe the level meter
for a -10 dBm reading
36.
Remove power, and plug the 44022 back in
37.
Reapply power
38.
Listen to the speaker for a 1 KHz tone.
39.
Place an audio amplifier with a speaker attached to it to B pins 8
and 10. The 1 KHz tone should be heard.
