UNDER
TEST
Front-panel controls are
set
the same
as
for voltage measurements. The
test oscilloscope 0.4 Volts calibrator
signal is
applied to both
the
EVENTS
and
START
INPUTS.
TEST OSCILLOSCOPE
The
test oscilloscope
is
dc coupled and
externally triggered
from
the
CALIBRATOR OUTPUT
only where
1
kHz
calibrator signals are present, and internally triggered on
all
other waveforms.
Tolerances of
voltages and waveforms shown
are
20%.
