Voltage Conditions
Voltages shown on this schematic diagram were measured w ith a Tektronix DM 502A Digital Multimeter.
Voltage measurements can vary as much as ±20%. No signals were applied to the vertical inputs or to EXT-
ernal trigger input.
Waveform Conditions
Waveforms below were taken from a Tektronix 475A Oscilloscope. Waveforms may vary as much as
±
20
% .
A 50 kHz, 100 mV sine wave was applied to the Channel 1 input and a 50 kHz, 2 V square wave was
applied to the Channel 2 input. A Tektronix SG 503 provided the sine wave and a Tektronix FG 502
provided the square wave.
