TEST OSCILLOSCOPE SETUP
Test Oscilloscope Control Settings
Apply a 20 mV

p,
positive-going
square wave from the
Calibration Generator to the
CH 1 or X input connector.
Connect the 465B
A +GATE (from the 465B rear panel)
to
the test oscilloscope external
trigger input connector.
Use
no terminations.

Connect a 10X probe to the Channel
1 input of the test
oscilloscope.
Apply the probe tip
to
the
test point or Com
ponent lead as indicated
on
the
schematic and the com-
ponent
board layout Figure associated
with that schematic.
DC VOLTAGES
Typical
voltage
measurements were obtained with the instrument operating under the
conditions noted in
the control
settings adjacent to each schematic diagram. Voltage measurements
were taken with no signal applied
to
the
vertical or
trigger inputs. All voltages measured with reference to chassis ground. Voltages rounded
to the nearest tenth of
a
volt.
