Huntron Access DH2 robotic prober

The Access DH2 Prober is a dual head robotic flying probe system suited to low-volume PCA testing where the interfacing between two points is necessary.

The open architecture design of the Access DH2 makes it possible to utilise flying probe technology for many different test methods where automated probing of the PCA under test is required. The Access DH2 can be used with traditional Huntron Tracker products, configured to work with conventional test instruments (oscilloscopes, spectrum analysers, etc) or specialised test cards such as boundary scan. The Access DH2 design also allows a plug-and-play approach to automating manual guided probe applications.

The Access DH2 is a refined and updated version of the original Huntron dual head Access DH prober, the most noticeable change is the size. The Access DH2 has been resized to fit through a standard 91.4 cm door. The probing area is same as the original Access DH, but wider and not as deep, improving the probing area. The redesigned cabinet now has two side-by-side 48.3 cm instrument racks making system integration more convenient.

Using the Access DH2 to make measurements on powered circuit boards with the RG316 coax cable connected to the test probes will allow the user to make higher frequency measurements with oscilloscopes and spectrum analysers. The motor control has also been improved and the vision system enhanced with higher resolution, auto-focus cameras and software-controlled ring lights.
