Ratio between 32fH component and 32.5fH
component
T28A VIN = white 50% + CW (15.8 mVp-p)
Ratio between 32fH component and 32.5fH
component
T34A Apply VIN = 0.5 Vp-p video signal to pin 4,
and determine ratio between T34A output
level and input level
T34A VIN = white 50% + CW (f = 1 MHz, 158
mVp-p)

T34 With VIN = white 100% and T34A at 1.0
Vp-p, measure electric potential for each of
the pin 34 video output sync tip, pedestal,
and white peak, and assign the measured
values to LSYN, LPED, and LWHI, respectively
T34 Measure pin 34 DC voltage when 5 V is
–80
applied to pin 33, and assign the measured
value to LVDP, and calculate the difference
with LSYN
∆ VDP = LSYN – LVDP
T34 Measure pin 34 DC voltage when 2.7 V is
–300
applied to pin 33, and assign the measured
value to LHDP, and calculate the difference
with LPED
∆HDP = LPED – LHDP
T34 Measure pin 34 DC voltage when 1.3 V is
20
applied to pin 33, and assign the measured
value to LWHP, and calculate the difference
with LWHI
∆WHP = LWHI – LWHP

T32 VIN = 0.5 Vp-p video signal, T32 output pulse 4.4
width
T32 VIN = 0.5 Vp-p video signal, measure delay 0.9
time of output SYNC versus input SYNC
T30 Measure DC level of T30 in REC mode
