Non-Store Displays
Single Sweep Display
You can use the following procedure to display a single sweep in
the SGL SWEEP trigger mode:
Step 1. Switch the 2212 on and obtain a baseline display in Non-
Store mode.
Step 2. Apply a test signal to the CH 1 OR X input to be used for
setting the trigger LEVEL control.
For random signals, set the Trigger LEVEL control to
trigger the sweep on a signal that is approximately the
same amplitude as the random signal.
Step 3. Set the CH1 VOLTS/DIV switch and adjust the Vertical
POSITION control to display the waveform correctly
within the graticule area.
The Horizontal POSITION control should be adjusted to
place the start of the sweep about one division from the
left edge of the crt.
Step 4. Toggle the Trigger MODE to NORM and adjust the Trigger
LEVEL control carefully until the display is stable.
Step 5. Toggle the Trigger MODE to SGL SWP and check that the
sweep triggers when the RESET button is pressed.
If it does not trigger, readjust the Trigger LEVEL control
slightly so that the sweep triggers each time the RESET
button is pressed.
If no trigger signal is present, and the RESET button is
pressed, the READY indicator LED should illuminate to
indicate that the sweep generator circuit is set and ready
to initiate a sweep when a trigger is received.
Step 6. When the single sweep has been triggered and the sweep
is completed, the sweep logic circuit is locked out.
Another sweep cannot be generated until the SGL SWP
RESET button is pressed again to set the sweep to the
READY state.
Step 7. Disconnect the test signal from the CH1 or X input, apply
the random signal to the CH1 OR X input and press the
RESET button to set the sweep to the READY state.
