In the dialog box, select the probe head and the type of
calibration. Click Start and follow the instructions shown on
the oscilloscope.

When performing the skew calibration, you will be instructed
to use the PV fixture. Observe these points:
❏
Connect the PV fixture's input to the oscilloscope's
calibration output. Connect a 50 ohm terminator to the
PV's output.
Figure 10
❏
Position the probe so that the signal lead touches the
PV fixture's center conductor next to the dialectric
area. The ground lead should touch the PV fixture's
ground plane. On 90000 X- series oscilloscopes, use an
N5442A adapter when instructed to connect the probe
to one of the oscilloscope's channel inputs.
CAUTION
To avoid damaging the oscilloscope's Cal Out connector, do not apply force
to the PV fixture. Light probe contact is all that is needed for the
calibration.
CAUTION
NEVER solder a probe tip to the thick-film gold. The gold will immediately
dissolve into the solder and disappear.
NOTE
If you are using the browser tip, it is recommended that you use the
N2787A 3D Probe Positioner to hold the probe in place.
