MX0025A
Best probes for measuring signals found in the latest DDR5 and MIPI standards.
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.
N2796A
Ideal for digital system design, component design/characterization, and educational research applications.
The N2796A is a new generation of low-cost, single-ended active probe with the AutoProbe interface. The probe integrates many of the characteristics needed for today’s general-purpose, high-speed probing - especially in digital system design, component design/characterization, and educational research applications. Its 1MΩ input resistance and extremely low input capacitance (1 pF) provide ultra low loading of the DUT. This, accompanied with superior signal fidelity, makes this probe useful for most of today’s digital logic voltages. And with its wide dynamic range (±8 V) and offset range (±12 V), the probe can be used in a wide variety of applications.
For high signal integrity probing, the N2796A 2 GHz active probe is a perfect complement to Keysight’s 1 GHz bandwidth Infiniium and InfiniiVision Series scopes. The N2796A can also be used with Keysight’s 2.5 GHz or higher bandwidth Infiniium 9000 or 90000 Series scopes as a low-cost alternative to 1156A-1158A active probe or InfiniiMax probe.
The N2796A is equipped with a white LED headlight to illuminate the circuit under test. The probe is powered directly by the InfiniiVision and Infiniium AutoProbe interface, eliminating the need for an additional power supply. The probe also comes with a number of accessories that allow for easy connections to the circuit under test.
11059A

The N2873A passive probe offers DC to 500 MHz and 10:1 attenuation factor to address a wide range of measurement needs.
Compact 2.5-mm probe head diameter, low input capacitance, and various fine-pitch probe tip accessories make the Keysight N2870A Series passive probes ideal for probing densely populated IC components or surface-mount devices used in today’s high-speed digital applications.
The sharp probe tip is spring loaded to help engineers keep the probe from slipping off the device under test. Insulating IC caps keep the small probe tip centered on the IC lead and keep it from shorting adjacent leads. Standard flat blade ground connector and self-adhesive copper ground pad help reduce ground inductance while offering easy ground access. Optional probe tip accessories provide specialized capabilities for demanding applications.
Compatible with Keysight InfiniiVision and Infiniium Series oscilloscopes with 1 MΩ input. This probe ships with Keysight’s 9000 Series Infiniium oscilloscope.

N5425B
Probe signals with a considerable amount of test points in tight spaces, such as a DDR memory system.
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.
