• 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.

N1027A is a collection of accessories for DCA-X mainframes, modules and stand-alone DCA-Ms in Keysight's Digital Communication Analyzer (DCA) family. The accessories can be grouped into:

• Kits including multiple parts for specific applications (e.g., N1027A-46A for the N1046A 100+ GHz Electrical Remote Sampling Heads)
• Individual components needed for measurements (e.g., N1027A-PT2/PT3 phase trimmers to adjust skew between electrical channels)
• Items for protection and storage (e.g., N1027A-1MC storage case for mini-modules with remote heads)

• Adjust UXR-Series Oscilloscopes up to 110 GHz.
• Ruggedized 1.0 mm Female probe head.
• AutoProbe III interface.
• 3.5 mm Male RF Cable input.
• Probe Head Torque: 10 in-lb.

The Infiniium UXR-Series is the first real-time oscilloscope to offer an optional self-optimization module – capable of performing the frame adjustments to align internal correction constants under site environmental conditions. Optimization modules are available for all UXR-Series bulkhead connector types and supported bandwidths.

A full factory certified calibration consists of frame calibration adjustments, and subsequent testing and performance verification to ensure the oscilloscope is performing to its documented specifications. The optimization module performs only the factory-quality frame adjustment calibration steps. Additional instruments and components are necessary to perform the required horizontal adjustments and vertical performance verification procedures to achieve a full self-verified calibration. If an accredited certified calibration certificate is required, the UXR must be returned to a qualified Keysight service center.

• 21 GHz bandwidth -- when used with InfiniiMax MX0023A probe amp
• Connect to SMA fixtured differential pairs
• Frees additional oscilloscope channels by using a single channel to measure differential signals
• Includes semi-rigid coax to change span between SMA connectors
• Allows for termination to a common DC voltage (± 4 V) rather than a ground
• Max input voltage =2.28 Vrms (Vin-Vcm_term)

The MX0105A is a differential SMA probe head that provides 21 GHz of bandwidth and allows you to connect two SMA cables to make differential measurements on an oscilloscope channel. The SMA head allows for termination to a common DC voltage (± 4 V) rather than a ground that would be required for signal standards such as HDMI and MIPI Mphy. The termination voltage is applied externally using the supplied cable and a DC power supply.

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.
