Pin arrangement
The 9139B Probe Card Adapter has 64 pins, each rated to 1100 V. All pins in the 9139B can
accommodate low-current signals.
The pins are arranged into symmetric sectors around a central point.

Leakage paths, low-current and high-voltage capabilities
The 9139B Probe Card Adapter provides 1.1 kV capability to each of its 64 pins. It also significantly
improves low current leakage and settling time on each pin compared to the 9139A-PCA.
The 9139B Probe Card Adapter includes triaxial connectors that meet safety spacing requirements
and are compatible with existing triaxial mating connectors. This allows the included triaxial cables to
easily connect to the test hardware.
