5-3. Signal Timing
See figures on page 8.
5-4. Video Output
Amplifier response
The video amplifier produces a drive signal at the
cathodes
of the
CRT
of sufficient
amplitude
to
produce a spot luminance with rise and fall times of
less than 12 nsec. from 10% to 90% pulsed level,
Cathode
voltage is 30Vp-p./Signal source is 75
ohm
impedance
and oscilloscope impedance
is
5pF,1M ohm.
