The Agilent 10936B Servo-Axis Board is a programmable, digital servo with built-in motion control algorithms. The combined servo-axis board provides a complete closed-loop positioning solution for Agilent 5527B laser interferometer systems. Outputs include ±10 V analog, pulse-width modulated, and 16-bit digital for a variety of commercially-available motors and amplifiers.

Custom algorithms can be downloaded to tune the servo for application requirements. A trace capability optimizes and verifies system performance. Special features include coordinated multiaxis moves, velocity profiling, buffered position profiling, and drive enable/disable.
