7. Verify that the time base operates: Confirm the following statements.
H
One period of the square-wave probe-compensation signal is about five
horizontal divisions on-screen for the 200
s/div horizontal scale setting.
H
Rotating the horizontal SCALE knob clockwise expands the waveform
on-screen (more horizontal divisions per waveform period), counter-
clockwise rotation contracts it, and returning the horizontal scale to
200
s/div returns the period to about five divisions.
H
The horizontal POSITION knob positions the signal left and right
on-screen when rotated.
8. Verify horizontal delay:
a.
Center a rising edge on screen:
H
Set 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 . . . .
H
Click the
Horizontal
tab in the control window that displays.
H
Click the Delay Mode button to turn delay on.
H
Double click the Horiz Delay control in the control window to
display the pop-up keypad. Click the keypad buttons to set the
horizontal delay to
500 s , and then click the ENTER key.
c. Verify the waveform: Verify that a falling edge of the waveform is within
a few divisions of center screen.
