Stability of mod.
depth
Differential gain
Differential phase
Amplitude response of video signal; V
sine signal between black and white
Period of time required for peak white detector to reach steady state for full modulation depth with
1-white pulse per half frame when control is already in the steady state
Setting time for video signal change from 0 Vpp to 1.4 Vpp; video blanking signal content is
uniform white level
Setting time for video blanking signal from 100% white level to 42% grey level with subsequent
rise in grey level to 71% of video blanking signal (due to decontrol process)
