4. ADJUSTMENT

Note 1 :

Perform this adjustment more than 30 minutes after power ON.

4.1 Devices Used

1. Spectrum analyzer (Equivalent to Advantest R3265A)
2. Oscilloscope (Equivalent to IWATSU SS-5711)
3. Digital voltmeter (one which can display more than 2 decimal

places)

4. Video SG (Equivalent to SHIBASOKU TG7/1)
5. Variable resistance attenuator (Equivalent to ANRITSU

MN510D)

6. Audio analyzer (Equivalent to HP 8903B)
7. TV modulator (Equivalent to EIDEN TV IF MOD 115K + UP

CONV 115K)

8. CATV terminal (Equivalent to PIONEER BA-6300)
9. TV demodulator (Equivalent to EIDEN 463B-B)
10. CW generator (One which can output 100.15 MHz, 60 dBmV/

75 

Ω

)

11. BTSC audio multiplexing modulator (Equivalent to EIDEN 465Z

series)

12. BTSC audio multiplexing demodulator (Equivalent to EIDEN

466B)

13. VHF amplifier (Equivalent to EIDEN 801C)

Video System

Note 2 :

If the time axis on the oscilloscope screen deviates or to
move to a clearer position on the screen, adjust finely using
Delay. However, do not change the vertical axis and
horizontal axis ranges.

Note 3 :

When reading the waveform on the oscilloscope screen,
read the center of the waveform noise.

Note 4 :

If the oscilloscope signal waveform is difficult to read,
adjust the luminance.
