Agilent/Keysight E1735A

The E1735A USB Axis Module is an electronic interface that connects the Keysight 5519A/B laser head to a host PC within the Keysight 5530 Dynamic Calibrator System. The module provides interfaces for optional remote control units and A-quad-B encoder inputs, enabling precise measurement and control across multiple axes. Communication with the PC occurs via high-speed USB 2.0, supporting Microsoft Windows 98 and later operating systems.

Its compact 102 × 63 × 24 mm form factor and 220 g weight facilitate integration into diverse calibration and testing environments.
