Figure 4: Probe Comp connections.
Connect the probe tip to the 1 kHz source and the ground clip to the ground. For best results, remove any probe tip accessories and
hold the probe tip directly onto the 1 kHz connector.
Note: Connect only one probe at a time to the PROBE COMP terminals.
3.
Turn off all channels.
4.
Turn on the channel to which the probe is connected.
5.
Push the front-panel Autoset button. The screen displays a square wave.
6.
Double-tap the badge of the channel that you want to compensate.
7.
Tap the Probe Setup panel.
If the Probe Compensation Status says Pass, the probe is already compensated for this channel. You can move the probe to another
channel and start again from step 1 or connect a different probe to this channel and start from step 1.
If the Probe Compensation Status says Default, continue with this procedure.
8.
Tap Compensate Probe to open the Probe Compensation dialog.
9.
Tap Compensate Probe to run the probe compensation.
10. The probe compensation is finished when the Probe Compensation Status displays Pass. Disconnect the probe tip and ground from
the PROBE COMP terminals.
11. Repeat these steps for each supported passive probe that you want to compensate for this channel.
12. Repeat these steps to compensate supported probes on other channels of the oscilloscope.
Note: For most accurate measurements, open the Probe Setup panel and verify the Probe Compensation Status is Pass
whenever you attach a probe to a channel.
Note: A probe compensation failure is most likely due to intermittent connection of the probe tip or ground connection during
the probe compensation operation. If a failure occurs, the oscilloscope will re-use the old probe compensation values if they
existed prior to the failed probe compensation operation.
Compensate passive probes
Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. Use this
procedure to adjust probe compensation for probes with a manual adjustment.
About this task
A passive probe is only adjusted for one channel at a time. If you move a passive probe to another channel, you must compensate that
probe to that channel.
Procedure
1. Connect the probe to the channel where you want to use it to take measurements. Remove all other probes.
