Keysight’s MX0025A InfiniiMax Ultra Series probe amplifier improves usability because you can measure differential, single-ended, and common mode signals with a single probe tip.

When you use a probe to connect your signal to your oscilloscope, it becomes part of the circuit affecting your test. Your probe may be hiding signal details, loading down your signal, or distorting it. InfiniiMax Ultra Series probes have the lowest loading for minimal impact to your circuit. Boost your test margins and gain measurement confidence with their unprecedented accuracy. Ensure your entire measurement system is helping you see the truest representation of your signal.

These probes have the lowest noise and capacitive loading and the lowest loading across more frequencies due to their RC high impedance profile. The InfiniiMax Ultra Series supports InfiniiMode and has a user-defined AC calibration mode, a wider input voltage range, more accuracy with unique S-parameter characterization, lower capacitive loading, a wider input voltage range, micro / socketed probe heads for smaller density probing, and more bandwidths. The InfiniiMax Ultra Series has an RC input impedance architecture with the lowest loading and least signal distortion across the widest frequency range.

InfiniiMax Ultra probes have three attenuation ranges — 1:1, 4:1, and 8:1 — giving you superior noise performance and large voltage ranges, all while maintaining maximum bandwidth. The input range automatically configures depending on the size of the input signal and vertical scale of your oscilloscope.

Choose from the three flexible input dynamic ranges from 600 mVpp at 1:1, 2.5 Vpp at 4:1, and 5 Vpp at 8:1. Clearly see and know when your design is satisfactory, keep up with standards, easily probe small devices, and reduce test complexity with the InfiniiMax Ultra Series probes.

The Keysight kelvin probe set consists of two gold-plated flat tweezers with special gripping surfaces. This design assures a very precise contact to the component and very precise measurements. The ground guard connector removes ground-related errors. The gold plating helps to reduce the contact resistance between the surfaces of the test probe and the lead of the component being measured - reducing overall error!

For probing signals with a considerable amount of test points in tight space such as DDR memory system, the N5425B ZIF probe head with the ZIF tip may be the best solution for you.

ZIF (zero-insertion-force) probe heads and tips can reduce probe costs significantly when many measurement points are needed. The ZIF probe head requires ZIF tips that can be soldered down to various places on a circuit board. The ZIF probe head can then be shuttled between these tips to make measurements.

It has a flat frequency response all the way to 18 GHz when used in conjunction with the MX0023A InfiniiMax 25 GHz RC probe amp and is the most economical solder-in probe solution on the market today.

The probe head does not include any ZIF probe tips. Either the N5426A ZIF tips or N5451A long-wired ZIF tips should be ordered with these probe tips.
