Using InfiniiMax III+ Series Probes
To Use InfiniiMode
InfiniiMode allows you to switch between differential, single-ended, and common
mode measurements without needing to change or reconnect the probe or probe
leads. Switching measurements is accomplished using the oscilloscope’s probe
configuration dialog box.
The N2848A QuickTip, N2836A Solder-In head, and N5444A SMA head are
InfiniiMode compatible.
The following table shows, depending on the probe tip and InfiniiMode setting,
which signal types can be measured.
Making InfiniiMode connections
When probing a differential or common mode signal, connect the probe tips as
shown in Figure 15 . The positive (+) and negative (–) leads can be reversed by
swapping the connections at the probe amplifier.
NOTE
InfiniiMode is available when using InfiniiMax III+ N2830/1/2A and N7000/1/2/3A probes.
InfiniiMode is not available when using InfiniiMax I, II, or III probe amplifiers.

NOTE
Because the N5445A browser tip has two leads instead of three, it is not InfiniiMode
compatible. However, you can still use the browser tip to measure single-ended signals by
selecting differential mode and touching one tip to ground.
