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 the 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 ap­
plied to the Channel 2 input. A Tektronix SG 503 provided the sine wave and a Tektronix FG 502 provided
the square wave.
The 442 controls were set as follows:

Channel 2 VO LTS /D IV 1 V
Other controls were set as needed to obtain a stable display.
For waveform 7, the SEC/DIV switch was set to 0.2 ms.
