1
Using the 50-
Ω
feedthrough and the
BNC
cable, connect the signal
generator to channel 1 of the oscilloscope.
2
Set the frequency of the signal generator to 250 kHz and the
amplitude to about 800 mV.
3
Press
Autoscale
.
4
Adjust the output of the signal generator for exactly 8 divisions of
vertical deflection.
5
Change the frequency of the signal generator to the value shown
below for your instrument.

Channel 3 — 100 MHz 250 MHz —
Channel 4 — 100 MHz 250 MHz —
*1mv/div to 5 mv/div dc = 100 MHz.
6
Change the sweep speed of the oscilloscope to 5 ns/div and observe
the display.
The vertical amplitude of the signal on the display should be equal to or
greater than 5.66 divisions (
−
3 dB point). If the result is not
≤−
3 dB, see
"Troubleshooting the Oscilloscope," on page 4–40.
7
Repeat steps 1 through 6 for channel 2 (channels 2 to 4 on the
HP 54601B and HP 54602B).
