8. Connect the probe output to the oscilloscope vertical input.
9. Connect the probe tip through the probe-tip-to-BNC adapter and a 50 W
termination to the positive-going fast-rise output of the calibration generator.
(The light gray probe-body shell must be removed before inserting the probe
tip into the probe-tip-to-BNC adapter.)
10. Verify that the high-frequency aberrations do not exceed +6% (5.30
divisions), –6% (4.70 divisions), or 9% (0.45% division) peak to peak, in
addition to the system aberrations noted in step 5 above.
11. If the probe aberrations are within tolerance, proceed to step 14 below. If the
probe aberrations are not within tolerance, continue with step 12 below.
12. Adjust R2021 for the best overall waveform flat response. See Figure 8 for
the location of all adjustments.
13. Adjust R2020, R2010, and C1010 for the best corner response without
ringing. See Figure 9 for the waveform area effected by each adjustment.
NOTE. High-frequency compensation adjustments affect probe bandwidth.
Following the compensation adjustments, verify the probe bandwidth specifica-
tion using the procedure on page 8. A small overshoot on the leading edge of
the pulse may be tolerated in order to meet the bandwidth specification. The
overshoot should not exceed the typical aberrations described in step 10 above.
14. Reinstall the compensation box cover by performing the procedure described
in step 7 above in reverse order.
15. Disconnect the test setup.
