4–7
the 1103 probe power supply; the offset control setting is not
important.
5. Mate the GR ends of the male SMA-to-GR and 50
W
termination
adapters. Connect the mated assembly to the oscilloscope
calibrator output. Insert the P6205 probe tip firmly into the
termination adapter. See Figure 4–5 above.
6. Adjust the oscilloscope horizontal and vertical position controls
to display a waveform similar to the one shown in Figure 4–6
below.

7. Use the oscilloscope measurement capability to display and
measure the waveform rise time (from the 10% to 90% amplitude
points).
8. Verify that the probe rise time is equal to or less than 467 ps.
Rise Time Approximation
Use the following procedure to approximate the probe rise time
without an 11801B oscilloscope. The procedure requires a pulse
generator capable of producing a rise time step of 250 ps or less.
1. Use a 50
W
coaxial cable to connect the output of the pulse
generator directly to the oscilloscope input.
2. Set the time base to 1 ns/division and the vertical amplifier to
50 mV/division. Adjust the pulse for a duration of greater than
10 ns with an amplitude of 250 mV.
3. Save and then recall the waveform.
