Several versions available
Huntron offers several versions of its Access probers.
The main difference between the Access and Access 2 is size. The Access Prober is sized for small to medium dimension PCBs while the Access 2 Prober can handle larger PCBs. The Access 2 has additional vertical space to handle taller features on a PCB.
The dual head Access DH2 allows you to probe between two specific points whereas the single head prober requires a common connection used for the "return" line. The Access DH2 was designed as an open architecture system where the user can setup testing processes of their own design. The Access DH2 is built on its own cabinet with space underneath for additional test equipment.
There is also an Access RF which is a modified version of the Access 2 and is used for precise near field RF measurements. The standard probe holder that uses spring probes has been replaced with a special holder for a high quality Langer RF probe. The Access RF is also available with or without a spectrum analyzer.
