1730–Series Theory of Operation

4–8

and R885 generates a pulse through Q764. Q765 inverts the blanking pulse,
which is input to the blanking circuitry on Diagram 4.

The Calibrator is a common base amplifier, Q587, that is driven by a 100 kHz
square wave from the Microprocessor (Diagram 5). It is switched at the 100 kHz
rate. The gain is set by adjusting R689, the Cal Amp. The emitter current drives
the Low Pass filter (which is at least 30 dB down at 3.58 to 4.43 MHz) through
an analog switch, U585C, which is activated by the Microprocessor-generated
CAL.

VERTICAL OUTPUT
Diagram 2

The filtered video signal drives the signal input of a gain cell whose gain is
controlled by the front-panel V CAL and, when selected, VAR VERTICAL
GAIN. The gain normalized video signal drives an amplifier that can be
clamped at back porch time with either a fast or slow time constant clamp, which
is also selected by front-panel selection.

The Switchable Gain Amplifier input is the dc level shifted (Vertical Position)
output of the Gain Cell Amplifier. Amplifier gain is switchable between X1 and
X5 as selected by the front-panel X5 VERTICAL GAIN. Amplifier output
drives a Bridge Limiter that prevents the Vertical Output Amplifier from being
overdriven.

The Vertical Output Amplifier is driven by the processed video signal or, in Line
Select, by an appropriate combination of video and the Y-Axis portion of the
readout signal. The output amplifier has enough gain to drive the CRT
deflection plates, while providing the compensation for the deflection plate
capacitance.

The picture monitor out signal from the Channel Switch (Diagram 1) is
amplified and compensated to drive a 75

W

load by the Pix Mon Out amplifier.

In addition, a bright-up pulse is added to the picture monitor output signal.

Q684 drives the Gain Cell. It is a low impedance (to terminate the filters)
common base amplifier. The signal voltage off collector is approximately 0.5 V.

The Gain Cell (U578) is driven differentially; pin 1 is the signal input with a
–3.0 Vdc level plus the signal voltage. R675 determines the maximum gain of
the Gain Cell. The amount of gain is controlled by varying the difference
between the bases of the two transistor pairs controlling the signal current
flowing out of pin 6 or pin 12. The front-panel V CAL control, R700, sets an
input dc level on pin 10 of the Gain Cell. When Variable Gain is selected, the
