The Keysight InfiniiMax III+ probing system is the next generation of InfiniiMax probing, greatly expanding the measurement capabilities and usability of a probe capable of measuring all components of a differential signal. The built-in InfiniiMode technology allows you to switch to differential, single-ended, and common mode without adjusting probe tip connections.

Each individual InfiniiMax III+ probe amp contains its unique S-parameters, and this frequency response data is used with the S-parameters of the various probe heads to further flatten the probe’s magnitude and phase response for accuracy. Traditionally, probe correction uses a nominal model based on a typical probe amplifier instead of the specific amplifier. Generally, the biggest variation between probing systems is a result of the probe amplifier. The ability to correct a specific probe amplifier’s response results in a more accurate probe correction, which yields a more accurate measurement.

The N7000A Series probes come with new InfiniiMode operation modes. The InfiniiMode allows convenient measurements of differential, single-ended, and common mode signals with a single probe tip without reconnecting the probe from its connection point. Switching measurements is accomplished using the oscilloscope’s probe configuration dialog box. The N7000A probe InfiniiMode provides the following modes of operation.

•  A – B (differential)
•  A – ground (single-ended A)
•  B – ground (single-ended B)
• (A+B)/2 – ground (common mode)
