FM SIGNAL GENERATOR CONDITION
1.Test equipment connection is shown in figure. Modulation
2.Set the unit to "FM” mode. Modulation frequency
3.Set the radio frequency display and signal generator to Output leve!
100.10MHz.
4.Adjust the core of T201 so that the voltage measured in
signal mode is OmV(O0+20mV) in 300mV range.
5.Adjust T202 so that the distortion factor of L-CH is mini-
mized.
6.Repeat steps 4 and 5.
7.Make sure that the distortion factors of L-CH and R-CH
are nearly the same and minimum.
Note: The adjusting screwdriver used should be made of
resin.
MPX VCO ADJUSTMENT
1.Test equipment connection is shown in figure.
2.Set the unit to “on/auto” position.
3.Set the radio frequency display and signal genarator to
