9. Mate the GR connector ends of the 50
W
termination adapter and
the male SMA-to-GR adapter. Connect the mated assembly to the
oscilloscope calibrator output. Insert the probe tip firmly into the
50
W
termination adapter.

10. Press SELECT CHANNEL on the sampling head to enable the
corresponding input channel.
11. Set the oscilloscope volts/division to 5 mV.
12. Adjust the oscilloscope horizontal and vertical position controls
to display a waveform similar to the one shown in Figure 4–8
above.
13. Ensure that Waveform Averaging is enabled. Ensure that the
vertical description rise time filter is enabled. If not, repeat
Step 5 above.
14. Use the oscilloscope measurement capability to determine the
peak-to-peak amplitude of the pulse. Measure, calculate, and
record (in percent) the probe-plus-system aberrations (abs
p+s
) in
the first 4 ns of the waveform. Measure the peak negative-going
aberration (if any) and the peak positive-going aberration (if
any). The sum of the two is the peak-to-peak aberration in
percent.
