WEC 04085 DDI

The WEC-04085 Direct Dock Interface is a spring-probe based interface that eliminates the primary source of parasitics on an HP 4062 Test System. With our Direct Dock Interface, your old HP 4062 becomes a modern and viable test system for characterizing low current and low capacitance devices. 

Our Direct Dock Interface
Reduces stray capacitance and leakage current.
Reduces the practical current measurement resolution from about 4,500 fA to 80 fA.
Reduces the practical capacitance measurement resolution from about 3,500 fF to 500 fF.
Reduces test time and increases throughput.

In addition to being a low cost alternative to buying a new test system, the White Eagle Consulting Direct Dock Interface is also an excellent solution for companies who want a migration path to an Agilent 4070 test system. Our Direct Dock Interface uses a high performance probe card that is compatible with 4070 series test systems. 

Each purchase of a White Eagle Consulting Direct Dock Interface includes
The direct dock interface.
An insert ring for your specific prober.
Two blank probe cards.
