• 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 Keysight R347B noise source covers a 26.5 to 40 GHz frequency range. This waveguide noise source allows you to make accurate and convenient noise figure measurements on millimeter-wave devices. The R347B provides highly precise broadband noise at the input of the system or component under test. The noise figure meter then processes the ON/OFF ratio of noise power present in the system IF, and provides an accurate reading of noise figure and gain. The R347B noise source has remarkable ENR stability over time, which allows longer recalibration cycles and more accurate noise figure measurements.

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)
   

The Keysight 346B noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty, which are reflections of the test signals. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.

• Frequency range: 10 MHz to 18 GHz    
  
• VSWR: < 1.3:1
• Connectors: BNC (f) input bias / 3.5 mm (m)
• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies
