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 4
Volt
Calibration signal
from the mainframe under test
isconnected
to
the input of 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 AC
coupled
and
internally triggered.
Voltmeter common is connected to
chassis ground.
Tolerances
of voltages and
waveforms shown are
20%.
