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.
