6. Verify horizontal delay:
a. Center a rising edge on screen:
H Turn the HORIZONTAL POSITION knob so that the rising edge
where the waveform is triggered is lined up with the center
horizontal graticule.
H Change the HORIZONTAL SCALE to 20 s/div. The rising edge of
the waveform should remain near the center graticule, and the falling
edge should be off screen.
b. Turn on and set horizontal delay:
H From the Horiz/Acq menu, select Horizontal/Acquisition Setup to
open the Horizontal/Acquisition Setup control window.
H Click the Horizontal tab in the control window that displays.
H On the Horizontal tab, click Delay Mode to toggle delay mode On.
H Click on the Horiz Delay control text box to display the pop-up
keypad. Click the keypad icon to open the keypad. Use the keypad to
set the horizontal delay to 500 s, and click ENTER.
c. Verify the waveform: Verify that a falling edge of the waveform is within
a few divisions of the center graticule.
d. Adjust the horizontal delay: Rotate the upper multipurpose knob to
change the horizontal delay setting. Verify that the falling edge shifts
horizontally. Rotate the front-panel HOR IZONTAL POSITION knob.
Verify that this knob has the same effect (it also adjusts delay, but only
when delay mode is on).
e. Verify the delay toggle function:
H Rotate the front-panel HORIZONTAL POSITION knob to center
the falling edge horizontally on the screen.
H Change the HORIZONTAL SCALE to 40 ns/div. The falling edge
of the waveform should remain near the center graticule. If not,
readjust the delay setting to center the falling edge.
H Push the front-panel DELAY button several times to toggle the
delay off and on and back off again. Verify that the display switches
quickly between two different points in time (the rising and falling
edges of the signal).
7. Remove the test hookup: Disconnect the probe from the channel input and
the probe compensation terminal.
