Special Features

  • simple programming API (Windows)

The N1230A PCI three-axis laser position board is a register-based PCI bus board that implements three axes of laser interferometer measurement for position monitoring. There are three external individual axis sample inputs.

Several threshold compare registers with interrupt capability can be used for travel limit and in-window or out-of-window detection functions.

The user can programmatically access the externally-sampled position and velocity data as well as the software-sampled position and velocity data over the PCI bus at rates up to 5 kHz (3 axes of position and velocity) or 10 kHz (position or velocity only).
