To Ensure Maximum Measurement Accuracy
To increase measurement accuracy, use the oscilloscope’s Select Probe Head dialog
box to indicate the type of probe head that is attached to the probe amplifier.
Making this selection allows the oscilloscope to apply the proper type of correction
filter (S parameter) for your measurement case. The correction filter increases
accuracy by flattening the magnitude and phase response of the probe. The
following two sources of S parameters are automatically used for the filter:
• S parameters of the InfiniiMax III+ probe amplifier. These S parameters are
unique to and stored on the probe amplifier.
• S parameters of the specific probe-head model. For example, the N2836A: DF
Solder-In (Vertical) selection applies S parameters for the N2836A head held in a
vertical position (perpendicular to the surface of the DUT).
To display the dialog box, click Probes > Channel Setup Menu .
