To get the most out of your Keysight Technologies, Inc. Infiniium oscilloscope, you need the right probes and accessories for your particular applications. Whether you need the high bandwidth and low loading of an active probe, an easy way to connect to surface mount ICs, or a passive probe to measure high voltages, there’s a wide selection of high-quality probes and accessories for your Infiniium oscilloscope.
Probe Compatibility Table
To assist you in selecting the proper probe for your application use our probe compatibility table below to find the probes that are recommended for use with your Infiniium scope.

InfiniiMax Active Probe System Overview
For All High-Speed Digital Design Engineers
Get the highest performance available for measuring differential and single-ended signals on high[1]density ICs and PCBs. As devices get smaller and faster, accurately probing signals becomes more challenging. Keysight’s InfiniiMax Probing System has the most accurate probe amplifiers, the widest variety of probe heads, and all the accessories you need to get the job done.

Industry-Leading
The InfiniiMax probes can be divided into two main categories: RC and RCRC architecture. As pictured above, an RC input impedance architecture has the lowest loading and least signal distortion across the widest frequency range. At lower frequencies, you can see that the input impedance is driven by input R of the probe. It then intersects the capacitance of the probe. The RCRC architecture is best when higher bandwidth is necessary, or for signals that have low source impedance. You can see here that at higher frequencies the RCRC input impedance is slightly higher, making it a better choice for high bandwidth measurements. InfiniiMax I, II, RC, and Ultra all have RC architecture, whereas InfiniiMax III and III+ have RCRC architecture. You will need to choose the probe loading that best fits your application. Here are a few recommendations of when to use RC vs. RCRC probes.
InfiniiMode
In many of today’s high-speed serial bus standards, the accurate measurement of single-ended and common-mode components of a differential signal is often compromised by having to rely on multiple probe channels and a scope’s internal math functions, but these methods are prone to errors and cumbersome to use. InfiniiMode allows you to measure differential, single-ended and common-mode characteristics of a differential signal with a signal connection. You will need to connect four inputs consisting of two differential signal inputs: +lead, -lead and two ground connections to make the multi[1]mode measurements possible with a single connection. Once you connect all input leads to the target, you don’t need to reconnect the probe and it just takes one channel on the scope to make all three measurements. To make InfiniiMode measurements, you need both a probe amplifier and probe heads that are InfiniiMode capable.
Auto-Selected
Input Attenuation Ranges More attenuation ranges give you superior noise performance and larger voltage ranges all while maintaining maximum bandwidth. With auto-selected input attenuation ranges, the input range is automatically configured depending on the size of the input signal and the vertical scale of the scope.
True View and Source Estimate Probe Response Correction Modes
You can choose whether you want your probe to show you the voltage at the tip of probe (Vout/Vin - True View) as loaded by the probe or the estimate of the voltage at the probe point before the probe load was applied (Vout/Vsource - Source Estimate).
