PTRLNV/2/S3 and PTRL-NV/2/HP/S3 - Technical and Maintenance Manual
should be moved (the other end of the strip-line is connected to
the cathode of the varicap via caapacitor CX).
4)
If the calibrion procedure is being carried out after a change of
frequency, capacitor CX and impedance L4, situated on the VCO card, will
also have to be changed according to Table D.
5.8 STEREO CODER ADJUSTMENT
After replacement of the Stereo Coder, the following procedure
should be followed SETUP 3 (Fig.6):
1)
Select 0 dBm with the INPUT LEVEL selector (with stereo coder and
pilot tone inserted).
2)
Connect a low distortion sine wave audio generator to the inputs
L, R.
3)
Connect the RF output of PTRL-NV/S3 to a suitable load (50 Ohm-20W).
4)
Connect
a -30 dB
coupler
to
the
RF
input
of
F.A.M. (or other
Modulation Analyzer type).
