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.
NOTE . If the waveform front corner appears rounded or rolled-off, set
the left-limit measurement cursor at the first 100% amplitude point
of the waveform to determine aberrations. Refer to Figure 4–9.

7. Disconnect the coaxial cable from the oscilloscope calibrator
output and reconnect it to the channel 1 output of the 1103 probe
power supply. Remove the SMA-to-BNC adapter from the
oscilloscope calibrator output. See Figure 4–10 below.
8. Connect the P6205 probe output to the 1103 power supply
channel 1 input. The P6205 does not use the offset capability of
the 1103 probe power supply; the offset control setting is not
important.
