The N2831A Series InfiniiMax III+ probing system is the next generation of InfiniiMax probing, greatly expanding the measurement capability and usability of a probe capable of measuring all the components of a differential signal. The built-in InfiniiMode technology allows customers to switch differential, single-ended, and common mode without adjusting probe tip connections.

The N2831A Series probe’s InfiniiMode provides the following mode of operation:

• A – B (differential)
• A – ground (signal singled A)
• B – ground (signal singled B)
• (A + B)/2 – ground (common mode)

The InfiniiMax III+ works with the full array of InfiniiMax III probe heads and supports the full bandwidth of the InfiniiMax III+.
