COLOR CAMERA
EBI-6351
Viewfinder Switcher Board,
PL -7674431
The viewfinder switcher enables all video
switching for the viewfinder to be accom-
plished by d -c controlled diode switches.
The switcher board contains five identical
amplifiers and eight identical diode switch-
ing networks. Two of the amplifier stages,
luminance and auxiliary, are operated as
emitter
followers.
The remaining three
stages, red, blue, and green, are used as
both emitter collector followers in order
to obtain both polarities of these signals.
A coaxial connector for an external monitor
output is furnished and is located at the rear
of the Camera under the registration con-
trol panel.
Sync Adder Board, PL -7782689
The sync adder board is used to provide
sync pulses for triggering an external moni-
tor. There sync pulses are not NTSC but
are adequate to drive a monitor.
Viewfinder Video Amplifier Board,
PL -7672681 G3
The viewfinder video amplifier is a fixed -
gain,
broadband video amplifier designed
to drive the cathode of the viewfinder picture
tube.
Viewfinder Sweep Board, PL -767379702
The viewfinder sweep board furnishes the
horizontal and vertical sweep and blanking
for
the viewfinder cathode-ray tube. The
horizontal and vertical sweep voltages are
adjustable by using the horizontal and the
vertical sine controls.
General
Viewfinder High -Voltage Power Supply
Board, PL -778168402
This power supply is designed to provide
regulated 16 kilovolts for the Camera view-
finder cathode-ray tube from a
15,750 -
hertz sine wave input.
Iris Control Servo Amplifier Board,
PL -7782027G2
The iris control servo amplifier is de-
signed to drive a motor which in turn ro-
tates
the
lens iris. The servo amplifier
can be remotely controlled.
Iris Control Servo Power Supply
Board, PL -7673613
This board contains a transformer and re-
lated components necessary to generate +20
and -20 volts d -c. Both of these positive
and negative supplies are well regulated.
Two sets
of
rectifiers are connected in
opposite polarity
and supply the positive
and negative unregulated voltages for ap-
plication to the two series regulated cir-
cuits.
Intercom Amplifier Board, PL -7781675
An intercom amplifier board is located on
the left side of the Camera. The audio gain
control is panel -mounted under the registra-
tion control panel at the rear of the Camera
and is used to raise or lower the headset
volume. Telephone type dual jacks are pro-
vided as inputs to the Camera headsets.
117 -Volt AC Outlet
A 117 -volt a -c outlet and switch, provided
at the back of the Camera on the intercom
panel, may be used for a lead light, Soldering
iron, etc.
INSTALL A TION

has been tested and inspected before ship-
ment and should be ready for operation
when installed. Exercise care when handling
the Camera because of the optical and de-
flection assemblies. Be careful not to dis-
