ELECTRICAL CHARACTERISTICS TEST METHOD

P/N Video S/N

1. Input SG3 and measure the rms value of output signal a

pin 52.

2. P/N is defined as follows:

P/N = 20 log

VONEG Measured Value(VP-P)X103

Measured Value(mVrms)

(dB)

BW Video frequency characteristics

1. Input SG4 and set the frequency f2 to 37.9MHz so that

the beat element of 1MHz is output to pin 52.

2. Then set the applied voltage at pin 4 so that the beat

element of 1MHz at pin 52 may be 100dBµ.

3. Decrease f2 to the level at which the beat element

becomes 3dB smaller than the element of 1MHz, and

read the value at that level.

Vin min. Input sensitivity

1. Decrease SG5 level until the video detector output is 3dB

smaller than the measured value of Parameter V3 "Video

detector output".

Vin max. Maximum permissible input

1. Input 90dBu SG6.

2. VA is the output level at pin 52. Increase SG6 voltage

until the output at pin 52 becomes 3dB smaller than VA.

The input level at that time is the maximum permissible

input.
