Digital Storage Displays
Step 5. 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 so
that the start of the display is about one division from
the left edge of the crt.
Step 6. Set the Trigger MODE to NORM and adjust the Trigger
LEVEL control carefully until the display is stable.
Step 7. Toggle the Trigger MODE to SGL SWP and check that
the display is updated when the RESET button is
pressed.
If it does not trigger, readjust the Trigger LEVEL control
slightly so that the display is updated 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 trigger circuit is set and ready to update
the display when a trigger is received.
Step 8. When the single sweep has been triggered and the dis-
play is updated, the sweep logic circuit is locked out.
Another acquisition cannot be generated until the
RESET button is pressed again to set the acquisition
system to the READY state.
Step 9. Disconnect the test signal from the CH1 or X input, ap-
ply the random signal to the CH 1 OR X input and press
the RESET button to set the acquisition system to the
READY state.
Step 10. The trace starts rolling on from the right to the left of the
screen. Until the trigger event occurs, the READY light
will be on to show that the oscilloscope is armed and
ready to start the acquisition when the trigger occurs.
When (after the pretrig time) the random trigger pulse
occurs, the acquisition will be started, and one single
acquisition will be displayed on the crt screen.
Step 11. When the single sweep has been triggered and com-
pleted, another acquisition cannot be started until the
RESET button is pressed again to rearm the acquisition
circuit.
