1. Video S/N 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. S/N=20 log 0.7 X V 0 det NOISE 2. Video Band width: BW 1. Measure the 1MHz component level of Video output TP22A with a spectrum 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. 2. Reduce f2 and measure the value of (f2-f1) when the (f2-f1) component level reaches -3dB from the 1MHz component level as shown below. (dB)
