Active Differential Probes
InfiniiMax probes provide a versatile probing solution for both single-ended active and differential probing. InfiniiMax probes consist of the probe amplifiers and probing heads listed below that attach to the probe amplifiers. All InfiniiMax probes connect to the oscilloscope using an AutoProbe interface.

Single Ended Probes
Single-ended active probes contain a small, active amplifier built into the probe body near the probe tip. This arrangement makes it possible to keep the probe input capacitance very low, usually less than 2 pF. This low capacitance results in high input impedance on high frequencies. It has the best overall combination of resistive and capacitive loading. With such low loading, active probes can be used on high-impedance circuits that would be seriously loaded by passive probes. Active probes are the least intrusive of all the probes.
