InfiniiMax Ultra Probe Amplifier, 25 GHz
MX0025A
Best probes for measuring signals found in the latest DDR5 and MIPI standards.
- Test and validate high-speed technologies such as DDR5 / MIPI with the 25 GHz probe amplifier (AP2).
- Experience the highest input impedance in midband frequencies for low-energy probing.
- Boost test margins with the lowest signal degradation.
- Probe small devices with the super-flexible micro probe head or choose from the widest variety of compatible probe heads for your unique application.
- Measure differential, single-ended, and common mode signals with a single probe tip.
- Use with Infiniium UXR-, 90000 X-, Q-, V-, and Z-Series oscilloscopes.
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 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.

Common Interface Unit
E7770A
The Keysight E7770A common interface unit (CIU) provides a bidirectional intermediate frequency (IF) interface to the device under test.
The Keysight E7770A common interface unit (CIU) provides a bidirectional intermediate frequency (IF) interface to the device under test (DUT) by up- or down-converting a sub-6 GHz uplink or downlink RF signal into a 6 to 12 GHz, or 7.7 to 14.5 GHz IF signal. This solution gives you the control, power, and local oscillator frequency input to the Keysight M1740A millimeter-wave (mmWave) transceiver for 5G remote radio heads (RRHs). As an up/down converter and RRH controller, the CIU supports the extension of the frequency coverage from sub-6 GHz to a high IF and mmWave bands.
The CIU is a key component of a wide range Keysight 5G solutions. These solutions provide the stimulus and analysis capabilities necessary to verify transceiver (Tx) and receiver (Rx) performance for 5G chipsets, devices, and base stations.
Quickly validate DUT performance over-the-air (OTA) with chambers designed for different test cases across the device workflow.
