V-Correction Adjustment (D02)

Preparation:
1. Ap ply a Crosshatch pattern.
2. Adjust (D01) so that V-Size is regular size.
3. If b- a<-1.5mm (in top and bottom) , increase (D02)
by one step and adjust (D01) so that V-Size is
regular; repeat steps until b-a≤1.5mm
4. If b- a> -1.5m m (in top and bottom), decrease (D02)
by one step and adjust (D01) so that V-Size is
regular; repeat steps until b-a≤1.5mm.

MTS Circuit Adjustments

The MTS Circuit Adjustments require two steps:
1. Inp ut Level Adjustment.
2. Ste reo Separation Adjustment.

Input Level Adjustment (M00)

Preparation:
1. Con nect an RMS meter with filte r jig as shown in
Fig. 37.
2. Con nect an RF signal generator to the RF
antenna input.
Procedure:
1. Ap ply the following signal from the RF signal
generator:
Video: 100 IRE flat field, 30% modulation.
Audio: 300Hz, 100% modulation, monaural
(70 ±5dB, 75Ω OPEN, P/S 10dB).
2. Ad just the MTS Input Level Adj ustment (M0) until
the voltage measured is 106 ± 6.0mV rms.

Stereo Separation Adjustment

(M01 & M02)

Preparation:
1. Connect an RF signal generat or to the RF antenn a
input.
2. Con nect oscilloscope to TPE10.
Procedure:
1. Se lect Stereo Mode in Audio menu
2. Ap ply the following signal from the RF signal
generator:
Video: 100 IRE flat field, 30% modulation.
Audio: 300Hz, 100% modulation, stereo (left only)
(70 ±5dB, 75Ω OPEN, P/S 10dB).
3. Ad just the MTS Low-Level Separat ion Adjustment
(M01) until the amplitude displayed on the scope
is minimum.
4. Apply the following signal from the RF
signal generator:
Video: 100 IRE flat field, 30% modulation.
Audio: 3KHz, 100% modulation, stereo (left only)
(70 ±5dB, 75Ω OPEN, P/S 10dB).
5. Ad just the MTS Hig h-Level Separ ation Adjustmen t
(M02) until the amplitude displayed on the scope is
minimum.
6. Rep eat above steps 2 through 5 until the amplitude
is minimum for both signals.
