NTSC MODULE
< 1a
1. 50/60 Hz detector
Disconnect 3000 from 15-1210. Inject a signal of 500 mV-55 Hz square wave (e.g. PM5107) into 3000. Adjust 3009 until the voltage on 11-7016 is at minimum. Measure the voltage on 2-7016. Now increase the voltage on 11-7016 by 3009 until the voltage on 2-7016 changes. Connect 3000.
2. Chrominance and Luminance bandpass
Disconnect 3052 from 13-1210. Inject a signal of 1.8 MHz, 500 mVpp into 3052 (PM5334). Connect an oscilloscope to 3-7092. Adjust 5076 for minimum signal amplitude of the oscilloscope picture.
Change input signal to 4.5 MHz, 500 mVpp. Adjust 5055 for minimum signal amplitude of the oscilloscope picture.
- Change input signal to 6.0 MHz, 500 mVpp. Adjust 5054 for minimum signal amplitude of the oscillos-
- cope picture.
Connect 3052
Disconnect 3025 from 2025.
Inject a signal of 4.5 MHz, 500 mVpp into 3025.
Connect the oscilloscope to 10-7092. Adjust 5028 for minimum signal amplitude of the oscillos-
cope picture. Change the input signal to 3 58 MHz, 500 mVpp.
Adjust 5029 for minimum signal amplitude of the oscilloscope picture. Connect 3025.
3. Brightness
Apply a signal from NTSC pattern generator (e.g. PM5512). Connect an oscilloscope to 9-1210. Adjust 3095 for black level at 2 Vdc.
4. Oscillator frequency
Connect the oscilloscope to 11-7092. Adjust 3095 for 2 Vdc on the oscilloscope picture. Connect 10-7092 to earth (27-7092). Apply a NTSC -4.43 MHz signal from an adapted PM5519 to the aerial input. Connect 6-7092 to 1-7092. Adjust 3050 in such a manner that the colour on the screen has practically come to a standstill. Now apply a NTSC -3.58 MHz signal from a PM5512 to the aerial input. Connect 10-7092 via a 10k resistor to 1-7092. Adjust 2084 in such a manner that the colour on the screen has practically come to a standstill. Remove the interconnections and the resistor.

ADJUSTMENTS
For adjustment 1 any colour signal may be used. Adjustment 2 and 3 are effected with a colour pattern generator PM5515 or PM5519.
1. Subcarrier oscillator
Apply a colour signal and set the receiver controls to their normal settings. Interconnect points 23 and 24 of 7292.
Include a 470 Ω resistor between point 6 and point 1 of 7292.
Adjust 2233 in such a manner that the colour on the screen has practically come to a standstill. Remove the resistor and the interconnection.
2. PAL-delay line
Apply a generator signal. Set the generator to position "DEM", adjust brightness to normal and the saturation control to 3/4 of its range. Adjust 3215 so that the venetian blinds effect in the third bar disappears.
Next, adjust 5210 so that the venetian blinds effect in the first and fourth bar disappears.
Readjust 3215.
Set the generator to "Colour Bar" position and adjust 5219 so that the venetian blinds effect in the third and/or the fifth bar from the left hand side (resp. cyan and magenta) disappears.
3. The 4.43 MHz trap in the luminance circuit
Use a colour bar pattern. The receiver is normally adjusted.
Connect an oscilloscope to point 10 of 7292 and adjust 5298 to minimum amplitude of the chrominance signal present on the various brightness steps of the luminance signal.
ADJUSTMENTS
For adjustment 1 any colour signal may be used. Adjustment 2 till 7 are effected with a colour pattern generator PM5515 or PM5516.
1 Subcarrier oscillator
Apply a colour signal and set the receiver controls to their normal settings.
Interconnect points 23 and 24 of 7082.
Include a 470 Ω resistor between point 6 and point 1 of 7082
Adjust 2038 in such a manner that the colour on the screen has practically come to a standstill. Remove the resistor and the interconnection.
2. PAL-delay line
Apply a generator signal. Set the generator to position "DEM", adjust brightness to normal and the saturation control to 3/4 of its range.
Adjust 3066 so that the venetian blinds effect in the third bar disappears. Next, adjust 5064 so that the venetian blinds effect in the first and fourth bar disappears. Readiust 3066.
Set the generator to "Colour Bar" position and adjust 5059 so that the venetian blinds effect in the third and/or the fifth bar from the left hand side (resp. cyan and magenta) disappears

ted
Set the generator to position "DEM", PAL system. Adjust 5064 until the two arey blocks in the top centre of the picture have the same colour If necessary repeat the adjustment of 3066 (see "PAL de-
lav line").
5. Secam demodulator
Set the generator to position "CONV.", SECAM system. Connect an oscilloscope to pin 3 on 7082. Adjust the time base of the oscilloscope such that at least 2 complete line durations are visible. Turn 3011 fully anti-clockwise, viewed from the component side.
Adjust 5010 until the amplitude of the chroma signal during one line equals that of the chroma signal of the next line. Adjust 3011 for minimum signal amplitude. If the signal of one line and the signal of the adjacent line do not reach their minimum simultaneously, 5010 should be readjusted slightly.
6. Chrominance response curve
Switch off the apparatus.
Apply the signal of a signal generator to 14-1200 via a 100 pF capacitor.
Connect an oscilloscope, aquipped with a 10:1 attenuation head to pin 4 on 7025.
Set the frequency of the signal generator to 4,32 MHz, unmodulated
Adjust 5004 for maximum signal amplitude of the oscilloscone picture Transfer the signal of the signal generator to 8-7025 via a
100 pF capacitor
Connect an oscilloscope to pin 3 of 7082.
Set the frequency of the signal generator to 4,3 MHz, unmodulated
Adjust 5036 for maximum signal amplitude of the oscilloscope picture. Set the frequency of the signal generator to 2,4 MHz.
Adjust 5034 for minimum signal amplitude.
7. 8.867 MHz rejection
Switch on the apparatus.
Apply a signal of 8.867 MHz of a signal generator (e.g. PM5326) to pin 20 of 7025 (± 30 mVpp). Connect an oscilloscope to the same point. Adjust 5013 for minimum signal amplitude of the oscilloscope picture.
.
8. Phase 8.867 MHz reference
Switch of the apparatus. Apply a signal of 6.5 MHz 100 mVpp via a resistor of 75 Ω to pin 25 of 7082. Connect an oscilloscope to 7 of 7025. Adjust 5041 for maximum signal amplitude of the oscilloscope picture.
