Precautions Concerning Measurements (Refer to Electrical Characteristics Test Circuit).
1. Start measurements after making the following adjustments.
2. Although no input conditions are indicated for C measurement Nos. 71 to 117, signal l is input from SG24.
3. Note that in regards to the measurements shown below, the characteristics change depending on the
4. When taking measurements, use metal film resistors with an allowable deviation of 1% for R1, R2, R3, and
1) Recording level (video AGC) adjustment
2) CAR adjustment (normal)
3) Chroma emphasis adjustment
Unless otherwise specified in the input conditions, the frequency for SG24 is 15.734kHz.

R5, and use temperature compensation CH types for C1, C2, C3, and C4.
11 to 13, adjust V31 so that the P34 (Pin 34 Y OUT) output is 500mVp-p when signal b (100% white,
500mVp-p Y signal) is input from SG30.
frequency of the P39 (Pin 39 Y RF OUT) output is 4.2MHz.
