“Smallest” solder-in probe head for high performance oscilloscopes

Keysight has launched its Keysight MX0100A InfiniiMax micro probe head – what it claims is the industry’s smallest solder-in probe head for high performance oscilloscopes, optimised for high-speed devices.

Keysight’s InfiniiMax micro probe head is a micro solder-in head for use with the company’s InfiniiMax I/II probe amplifiers and is designed to access small geometry target devices.

The lead wires can be adjusted to accommodate targets from 0mm to 7mm apart. When used in conjunction with Keysight’s 1169B 12 GHz InfiniiMax II probe amplifier, the MX0100A delivers up to full 12GHz bandwidth.

According to Keysight, the MX0100A offers the best probe loading performance in its class (0.17 pF, 50 kΩ differentially) and has a low input capacitance that minimises the probe loading effect and maximises signal integrity when measuring high-speed signals.

“Existing oscilloscope probe head solutions available today are even larger than the devices being tested in some cases. This makes signal probing access a continual challenge for modern electronic technologies,” said Dave Cipriani, Vice President of the Digital and Photonics Center of Excellence at Keysight Technologies. “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. It is the first, and only, of its kind on the market today.”
