High-Frequency Probe Compensation
The probe high-frequency compensation should seldom require
adjustment; however, your probe may require high-frequency
adjustment if any of the following are true:
H
the probe has high-frequency aberrations
H
the probe doesn’t perform at the rated bandwidth
H
the oscilloscope input capacitance is near the limits of the probe
compensation range in Table 1 on page 10.
To perform the high-frequency compensation adjustment you will
need a signal source that has all of the following characteristics (see
figure 3):
H
a square-wave output at 1 MHz
H
a fast rise output with rise time less than 1 ns
1 MHZ
t
r
<1 ns
90%
10%
>1 vpp

The Tektronix PG506A Calibration Generator meets these require-
ments when properly terminated.
