H Set the horizontal SCALE to 500 ps.
H From the tool bar, touch Horiz and select the Acquisition tab.
H Touch Average and set the number of averages to 16.
c. Hook up the test-signal source:
H Connect the sine wave output of a sine wave generator to a 50 Ω
precision coaxial cable followed by a power divider.
H Connect the power divider to both CH 1 and CH 2.See
Figure 4--21.

2. Confirm all four channels are within limits for channel delay:
a. Set up the generator: Set the generator frequency to 250 MHz and the
amplitude for six to eight divisions in CH 1.
Hint: As you are adjusting the generator amplitude, push PUSH TO
SET 50% frequently to speed up the updating of the waveform
amplitude on screen.
b. The horizontal SCALE should already be set to 500 ps. Now set it to
200 ps.
c. Save a CH 2 waveform: Press the CH 2 Vertical button. From the button
bar, touch the Refs button and select the Ref 2 tab. Touch the Save Wfm
to Ref2 Save button.
