Notes
1. Measure the 1MHz component level of Video output TP22A with a spectrum
2. Reduce f2 and measure the value of (f
1. Input SG5 (Vi=90dBµ) into VIF IN , and measure the level of the 20KHz
2. Gradually increase the Vi of SG and measure the input level when the
analyzer when SG3(f2=57.75MHz) is input into VIF IN. At that time,
measure the voltage at TP10 with SW10, set to position 2, and then fix
V10 at that voltage.

output reaches -3dB.
Input SG4 (Vi=90dBµ) into VIF IN , and then gradually reduce Vi and measure
the input level when the 20KHz component of Video output TP22A reaches -
3dB from Vo det level.
Input SG2 into VIF IN and measure the video out(Pin 22) noise in r.m.s
at TP22-B through a 5MHz (-3dB) L.P.F.
