b. Modify the initialized front-panel control settings:
H Do not adjust the vertical position of any channel during this
procedure.
H Set the horizontal SCALE to 500 ps.
H Press SHIFT; then press ACQUIRE MENU.
H Press the main-menu button Mode, and then press the side-menu
button Average 16.
c. Hook up the test-signal source:
H Connect the sine wave output of a sine wave generator (item 19 or,
optionally, 25) to a 50 W precision coaxial cable followed by a 50 W
termination, and a dual-input coupler. See Figure 1–10.
H Connect the coupler to both CH 1 and CH 2. See Figure 1–10.

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 about six divisions in CH 1.
Hint: As you are adjusting the generator amplitude, push SET LEVEL
TO 50% frequently to speed up the updating of the waveform amplitude
on screen.
