Step 5. Set the CHl 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 display 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 acquisition system has been triggered and the
display is updated, the sweep logic circuit is locked out.
Another acquisition cannot be generated until the SGL
SWP RESET button is pressed again to set the sweep to
the READY state.
Step 9. Disconnect the test signal from the CHl or X input and
apply 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. When the random trigger pulse occurs, the acquisition
will be started, and one single acquisition will be dis-
played on the crt 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.
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.
