Source: Keysight Technologies, Inc.According to Keysight Technologies, the new InfiniiMax micro probe head (MX0100A) is not only optimized for modern high-speed devices, but it’s also the industry's smallest solder-in probe head for high-performance oscilloscopes.

The MX0100A addresses some key issues: As the size of electronic devices continues to shrink, customers must contend with smaller pads and narrower pitch spacing; as data rates for applications such as DDR memory increase, conventional probing pads work as a stub and become a source for electromagnetic interference (EMI). As Dave Cipriani, Keysight’s VP of the Digital and Photonics Center of Excellence, explained, oscilloscope probe head solutions on the market are even larger than the devices being tested in some cases, making signal probing access a continual challenge.

The new probe head is designed for customers actively seeking high-density, small-geometry solutions for probing modern electronic technologies, and analyzing and measuring signals without interference. It is intended for use with the company's InfiniiMax I/II probe amplifiers. Lead wires can be adjusted to accommodate targets from 0 mm to 7 mm apart; when used in conjunction with the InfiniiMax II probe amplifier, the MX0100A will deliver up to full 12 GHz bandwidth.

Keysight also noted that the MX0100A offers the best probe-loading performance in its class (0.17 pF, 50 kΩ differentially), along with extremely low input capacitance that minimizes the probe loading effect and maximizes signal integrity when measuring high-speed signals.

"Unlike conventional solder-in probe heads in this class, Keysight specifically designed this micro probe to be less than half the size of existing solder-in probe heads for high density, fine pitch devices,” Cipriani added. “It is the first, and only, of its kind on the market today."

Keysight Technologies Inc., is a leading technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world.
