7. Verify that the time base operates: Confirm the following statements.
HOne period of the square-wave probe-compensation signal is about five
horizontal divisions on-screen for the 200 s/div horizontal scale setting.
HRotating 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.
HThe horizontal POSITION knob positions the signal left and right
on-screen when rotated.
8. Verify horizontal delay:
a. Center a rising edge on screen:
HSet the horizontal POSITION knob so that the rising edge where the
waveform is triggered is lined up with the center horizontal
graticule.
HChange 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:
HFrom the Horiz/Acq menu, select Horizontal/Acquisition
Setup....
HClick the Horizontal tab in the control window that displays.
HClick the Delay Mode button to turn delay on.
HDouble 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.
