Compensate the TPP Series probes
Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. The
oscilloscope can automatically test and store compensation values for an unlimited number of probe/channel combinations.
About this task
To access the user interface on a Low Profile instrument, connect a monitor to a video port on the rear of the instrument, and connect a
mouse to any USB Host port. You do not need to connect a mouse if your remote monitor is touch-capable. You can also remotely access
the user interface of a network-connected instrument by entering the instrument's IP address in a web browser.
To remotely set a control or run this task on a Low Profile instrument, see the instrument Programmer Manual (Tektronix part number
077-1305-xx) for the correct command or commands to use.
The oscilloscope stores the compensation values for each probe/channel combination, and automatically recalls the compensation values
when you plug in the probe. Probe compensation status is shown in the Probe Setup panel of the Channel configuration menu.
• If the Probe Compensation Status field displays Pass, the probe is compensated and ready for use.
• If the Probe Compensation Status field displays Default, the attached probe has not been compensated and needs to have this probe
compensation procedure run.
• If the Probe Compensation Status field displays Fail, the attached probe has failed the probe compensation procedure. Reconnect the
probe and run probe compensation again.
• If there is no probe compensation status field shown in the panel, the oscilloscope cannot store compensation values for that probe.
See the oscilloscope Help for how to manually compensate passive probes not supported by the probe compensation function.
Before you begin
The oscilloscope must be powered on for at least 20 minutes before compensating a probe.
Procedure
Use this procedure to compensate supported TPP-family probes that show a Default status when connected to the oscilloscope.
Note:
Doing a Default Setup does not delete probe compensation values. A factory calibration does delete all stored probe
compensation values.
1. Connect a supported probe to an input channel.
2. Connect the probe tip and ground lead of the probe to the PROBE COMP terminals.
Note:
Connect only one probe at a time to the PROBE COMP terminals.
