Setting up and Using DP0010A/12A/13A Probes
e
Use the N2787A 3D Probe Positioner to hold the probe in place and to
maintain a steady contact of probe tip with the deskew fixture.

Once the probe is properly connected to the deskew fixture, click the
Start Cal...
button to begin the DC gain/offset calibration.
Similarly, perform the skew calibration once the Atten/offset calibration is
successfully done. Use the
Start Skew Cal..
. button in the Probe Calibration dialog
box to initiate skew calibration.
CAUTION
To avoid damaging the oscilloscope’s Aux Out connector, do
not apply force to the PV fixture. Light probe contact is all that
is needed for the calibration.
NOTE
You can verify whether or not the probe tip is correctly connected to
the deskew fixture by
pressing the oscilloscope’s autoscale
button. If a stable step is displayed on screen, it indicates a
good connection. You will need to re-open the Probe
Calibration dialog box after performing this verification
step.
