You only need to perform the Bandwidth Performance Verification test with the ZIF tip as described
N OT E
above. If the probe passes with the ZIF probe head then it will pass with the browser probe head as well.
You are not required to test the bandwidth specification with both probe heads. If you have the choice
between using the ZIF probe head or the browser, Keysight suggests using the ZIF probe head because
measurements are more repeatable with it and it is easier to make a proper connection.
To measure the performance of the N5445A Browser with the N2803A probe amp, the
same procedure as described above is used except the browser is held in position with a
probe positioner. This setup is shown in
N2787A 3D Probe Positioner.
1 Tilt the browser slightly so the two tips touch the center trace and the ground plane on the
PV fixture at about the same time.
2 Probe the halfway point between the where the pinchers are and where the microstrip
transitions into the rectangular coax line.
3 Set the span of the browser to the minimum possible as should in this picture:
