• Clamp the probe leads to the PV fixture’s signal or ground. Position the probe
tips on the PV fixture as shown in Figure 21 . When using the solder-in tip, use
the fixture’s spring-loaded clamps to hold the leads.

Shown)
• On 90000 Q/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.
NOTE You can check that the probe leads are correctly connected by pressing the
front panel autoscale button. A stable step should be shown on the screen.
Pressing autoscale will close the Probe Calibration dialog box.
