Tektronix T921 User Manual

VI .2
VOLTAGE
CONDITIONS
Voltages shown on this schematic digaram were measured with a Tektronix DM 501 - Digital Multimeter . Voltage
measurements can vary as much as ±20% . No signals were applied to the vertical or the X (external trigger) input . See Waveform
Conditions for T922
or T922R control settings .
WAVEFORM CONDITIONS
Waveforms below were monitored with a Tektronix 7704A Oscilloscope, 71371 Time Base, and 7A15A Amplifier and a 10X
probe . The oscilloscope Input coupling was set to ac . Waveforms may vary as much as ±20% .
A 1 kHz, 50 mV sine wave was applied to Channel 1 input and a 1 kHz, 50 mV square wave was applied to Channel 2 input .
A Tektronix FG 501 Function Generator provides either of the input waveforms . .
The

As required
The other controls
were set as needed to obtain a display .
The CH 1 POSITION control was adjusted
so
that the
bottom of
the sine wave
was on
the first horizontal graticule line
above the center and the CH 2 POSITION control was adjusted so that the top of the square wave was on the first horizontal
graticule line below the center .
*Screen positions for waveforms 2, 3, 4, and 5 are affected by settings of the T922 or T922R POSITION controls .
