Follow the instructions on the oscilloscope to clamp the wires to either
the signal or ground. When connecting the probe wires to the fixture,
press down on the spring-loaded fingers described in Step 12 and
insert the probe wires. You can check that the wires are connected
correctly by pressing the autoscale button on the front panel and
checking that you have a stable step on screen (note that pressing
autoscale will close the Probe Calibration dialog box).
People tend to have their own preference for this step in terms of the
angle to view and insert the probe wires under the spring-loaded
fingers. Try different angles to determine your optimum method.
C A U T I O N When connecting the probe head to the fixture, do not press down with much force
or you could snap off the fixture from the Cal Out connection. Light contact is all that
is needed for the calibration.

If you are using the browser probe head, it is recommended that you
use the N2787A 3D Probe Positioner to hold the browser in place (as
shown below). The browser uses spring-loaded tips so you do not
need much force to get a solid contact. You can check that the tips are
connected correctly by pressing the autoscale button on the front
panel and checking that you have a stable step on screen (note that
pressing autoscale will close the Probe Calibration dialog box).
