TEST WAVEFORM SETUP INFORMATION
The numbered waveforms below were obtained
at
the test points indicated on the accompanying schematic diagram and
board dolly. The waveforms are representative
of
signals that may be expected
at
the associated points when the following
setup conditions are observed. Any change(s) from the given setup conditions required
to
produce
a
given waveform are
noted with that waveform illustration. Where
B
Sweep setup conditions are referenced with
a
waveform,
it is
assumed that
the
B
SEC/DIV knob is set
to
100 ^s/div unless otherwise noted.
