Waveforms
Waveforms
shown
on this diagram were obtained under
the following
conditions:
7623
OSCILLOSCOPE UNDER
TEST. Front
panel
controls
are set the same as for voltage measurements. A
7A15AN Vertical plug-in
unit and a 7B53AN Time Base
unit are
installed in
the mainframe under test. The test
oscilloscope 4 Volts calibration
signal is applied
to the
vertical
amplifier. The vertical amplifier is set for 1
V/Division
deflection centered
on the CRT. The
7B53AN is set for
free running sweep, 1 ms/Division
sweep
rate.
TEST
OSCILLOSCOPE. The test oscilloscope is
externally
triggered
from
the +GATE OUT (MAIN) of
the 7623
mainframe under
test. The test oscilloscope
is
AC
coupled.
Voltmeter common is connected to
chassis ground.
Tolerances
of
voltages and
waveforms shown are 20%.
