2. Set the TIME/DIV switches to X-Y and the VERT
MODE switch to CH 2. Apply the vertical signal to the
CH 2 OR Y input connector and the horizontal signal to
the CH 1 OR X input connector.
3. Advance the INTENSITY control until the display is
visible. If the display is not visible with the INTENSITY
control at midrange, press the BEAM FINDER pushbutton
and adjust the CH 1 and CH 2 VOLTS/DIV switches until
the display is reduced in size, both vertically and horizon-
tally. Center the compressed display with the POSITION
controls (CH 2 POSITION vertically, CH 1 POSITION
horizontally}; release the BEAM FINDER pushbutton.
Adjust the FOCUS control for a well-defined display.
SINGLE SWEEP DISPLAY
1. Obtain a Normal Sweep Display. For random
signals, set the trigger circuit to trigger on a signal that is
approximately the same amplitude and DT as the
random signal.
2. Push the SINGL SWP button on the A TRIG MODE
switch. The next trigger pulse starts the sweep and
displays a single trace. If no triggers are present, the
READY lamp lights, indicating the A Sweep Generator
circuit is set and waiting to be triggered.
3. After the sweep is complete, the circuit is “locked
out" and the READY lamp is out. Press the SINGL SWP
button to prepare the circuit for another single-sweep
display.
