Keysight Introduces High-Bandwidth Oscilloscope Probes


Keysight Technologies, Inc. introduces the InfiniiMax 4 Series high-bandwidth oscilloscope probes, expanding its portfolio of high-frequency probes to cover bandwidths up to 52 GHz. As the industry’s only solution with a high-impedance probe head operating at more than 50 GHz, the InfiniiMax 4 series provides digital designers with a turn-key probing solution for high-speed digital, semiconductor, and wafer applications.

As devices get smaller and faster, accurately probing signals becomes significantly more complex. The high-density integration and rapid signal speeds require advanced probing solutions that can maintain accuracy and minimise interference in such compact and fast-paced environments.

The Keysight InfiniiMax 4 Series probes address these challenges by providing a high-impedance probing solution for system verification without loading the device under test (DUT) that accelerates high-speed digital design, validation, and testing.

The new InfiniiMax 4 Series offers the following benefits:

  • Unparalleled bandwidth – Delivers the industry’s only probing solution operating up to 52 GHz Brickwall and 40 GHz Bessel-Thomson for PCIe 6.0 / 7.0, DDR5 / DDR6, MIPI Gear 5 / 6, and 802.3CK.
  • Faster debugging – Saves time and minimises errors as a turnkey solution with a high-impedance probe head and a modular design featuring an amp with multiple access points that bypasses the need for custom evaluation boards or interposers.
  • Innovative design – Offers industry’s first RCRC design with a flexible PCA probe head that uses the natural flexibility of the PCA to take the strain off the delicate tip wires. The removable flex PCA tips allows the most delicate portion of the tip to be removed and replaced.
  • Built on proven Keysight technology – Extends equipment investments through compatibility with Keysight’s real-time UXR-B Series oscilloscopes as well as the InfiniiMax III probe head.

Robert Saponas, Vice President, Keysight Digital Photonics Centre of Excellence, said: “The introduction of the InfiniiMax 4 enhances the future of probing with unmatched bandwidth and an unparalleled turn-key probing solution. The InfiniiMax 4 probes provide the precision, adaptability, and efficiency required to meet the demanding requirements of current and future high speed digital applications, ensuring that engineers and developers can keep pace with the rapid advancements in technology.”
