5-2-3.
Note:
Video Signal
Polarity: Positive
Signal level: Analog 0.7Vp-p/75 ohm
Horizontal Synchronization Signal
Polarity: Positive/Negative
Signal level: TTL level separate sync
Frequency : 30 kHz to 37 kHz continuous.
Auto size and center at 31.5 kHz,
35.2 kHz VGA/SVGA/8514A
standards.
Vertical Synchronization Signal
Polarity: Positive/Negative
Signal level: TTL level separate sync
Frequency: 50 Hz to 90 Hz continuous.
Non Interlaced or Interlaced modes.
Auto size and center for VGA/
SVGA/8514A standards.
The monitor detects vertical & horizontal sync
polarity and? automatically select its polarity and
frequency.
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.
