Compensation Adjustments
These probes can be adjusted for
low-frequency and high-frequency
compensation. For the best
measurement results you should
compensate your probe
to match its characteristics to
the oscilloscope. A poorly
compensated probe can
introduce measurement errors. Low-
frequency compensation should be
performed before performing high-
frequency compensation.
Low-frequency adjustment

Low-frequency compensation
1. Connect the probe from the
appropriate oscilloscope channel to
the 1-kHz square wave source.
2. Press Autoscale. Adjust the
oscilloscope to display two to three
cycles of the waveform over two to
six vertical divisions.
3. Set the low-frequency
compensation adjustment on the
probe for the flattest pulse possible
(see Figure 2).
Incorrect

High-frequency compensation

High-frequency adjustment
1. Using the BNC adapter, connect the
probe to a square wave generator
operating between 10-kHz and
1-MHz, and terminated into 50-Ω.
2. Press Autoscale. Adjust the
oscilloscope to display one cycle
of the waveform over two to six
vertical divisions.
3. Set the high-frequency
compensation adjustment on the
probe for the flattest, most square,
and most horizontal pulse possible
(see Figure 4).
