7. Verify horizontal delay:
a. Center a rising edge on screen:
■
Set the horizontal
Position
knob so that the rising edge where the
waveform is triggered is lined up with the center horizontal graticule.
■
Change the horizontal
Scale
to
20 μs/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:
■
Pull down the
Horiz/Acq
menu to select
Horizontal/Acquisition
Setup. . .
.
■
Click the
Horizontal
tab in the control window that displays.
■
Click the
Delay Mode
button to turn delay on.
■
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
1 ms
and then click the
ENTER
key.
c. Verify the waveform:
Verify that a rising edge of the waveform is within
a few divisions of center screen.
d. Adjust the horizontal delay:
Rotate the upper multipurpose knob to
change the horizontal delay setting. Verify that the rising edge shifts
horizontally. Rotate the front-panel horizontal
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:
■
Rotate the front-panel horizontal
Position
knob to center the rising
edge horizontally on the screen.
■
Change the horizontal
Scale
to
50 ns/div
(< 4 GHz models) or
40 ns/
div
(≥ 4 GHz models). The rising edge of the waveform should
remain near the center graticule.
■
Readjust the delay setting to position the rising edge 2 divisions to
the right of the center graticule line.
■
Push the front-panel
Delay
button several times to toggle delay off
and on and back off again. Verify that the display switches quickly
between two different points in time (the rising edge shifts
horizontally on the display).
8. Remove the test hookup:
Disconnect the test hookup from the instrument.
