VOLTAGE
CONDITIONS
Voltages shown
on this schematic diagram were measured with a
Tektronix DM 501 Digital
Multimeter . Voltage
measurements can vary as much
as ±20% . No signals were applied to the vertical input orthe X (external trigger) input . Referto
Waveform Conditions for T921, T922, or T922R control
settings . In the crt circuit, set the INTENSITY control for a voltage
measurement of +22 volts at the collector
of 0426 and of Q434 before attempting to measure voltages in the rest of the circuit .
WAVEFORM CONDITIONS
NOTE
Waveforms are for T922,
unless otherwise noted .
Waveforms below were monitored with a Tektronix 7704A
Oscilloscope, 71371 Time Base, 7A15A Amplifier and 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 CH 1 input and a 1 kHz, 50 mV square wave was applied to CH 2 input . A Tektronix
FG 501 Function Generator provides either
of
the input
waveforms .
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 .
For waveforms 6 and 7, the AC-GND-DC
switches were set to GND and SOURCE to LINE . Also for waveforms 6, and
7,
the LEVEL and INTENSITY controls were set to approximately midrange .
