Agilent Technologies  has introduced the InfiniiMax III oscilloscope probing system with bandwidth of 30 GHz. Four new probe amplifier models offer bandwidths from 16 to 30 GHz. A wide range of probe heads allows connection using a browser, ZIF (zero insertion force) tip, 2.92-mm or 3.5-mm SMA cable or solder-in tips. These probing solutions complement the new Infiniium 90000 X- Series oscilloscopes with bandwidth of 32 GHz.

Engineers working with high-energy physics, emerging wireline communication standards and high-speed serial data links, such as USB, SAS or PCI Express, use oscilloscopes to capture fast, single-shot events and to make critical measurements like jitter, while ensuring compliance to industry standards for interoperability. With data rates in the next few years extending beyond 10 Gbps, engineers need oscilloscopes that can deliver higher-bandwidth measurements. The probing system is a critical part of the solution.

Agilent used a proprietary indium phosphide (InP) integrated circuit process and state-of-the-art thick film packaging technology to achieve breakthrough performance within tight geometric constraints. The InfiniiMax III browser uses a novel "crisscross" blade grounding system for lower inductance grounding, a poly-iron wrap of coax tips to reduce standing waves, and very-low parasitic replaceable resistor tips to achieve industry-leading 30-GHz performance.

The InfiniiMax III probing system enables:

  • Real-time oscilloscope measurement system with the Infiniium 90000 X-Series oscilloscopes
  • Probing investment protection with bandwidth upgradability on probe amplifiers from 16 GHz to 30 GHz
  • Full-featured sampling oscilloscope probing solutions to 30 GHz with the Infiniium 86100C DCA-J
