8)
Measure the MONO signal level output by the receiver into the
audio
signal analyzer.
9)
Adjust TR3 for the maximum value and TR4 for the minimum.
10)
Set the audio analyzer to a measure audio distortion percentage with
a low-pass filter at 30 KHz.
11)
Adjust TR3 and TR4, alternately, to obtain the minimum MONO
distortion figure (typically 0.8%).
Having optimized the MONO figure, the STEREO figure should also be
optimized (typically 0.2%).
If this is not the case, adjust P1, TR1 and TR2, taking care not
to reduce excessively the amplitude of the 10.7 MHz IF signal.
5.4 CALIBRATION OF THE MUTING CARD
To carry out this procedure, configure the unit as detailed in
SETUP3:
1)
Inject a -83 dBm signal into the R.F. input of the receiver.
2)
Adjust potentiometer P2, situated on the 70 MHz IF card, to its
halfway position.
3)
Adjust trimmer R2, situated on the MUTING card, until the receiver
disables the audio signal.
5.5 CALIBRATION OF THE AUDIO PROCESS CARD
To carry out this procedure, configure the unit as detailed in
SETUP2:
1)
Check that trimmers R41 and R42, corresponding to the MONO and MPX
inputs, are at maximum.
2)
Check that jumper JP1 is in the correct position for the desired
de-emphasis (position A = 50µs "Europa" version; position B = 75µs
"America" version).
