How fast can I position the stage or read back sensor data with the USB interface?
The USB interface for the nPoint C300 controller can operate at a maximum command rate of approximately 500 commands per second. These commands can be split evenly between positioning and sensor monitoring (250 per second for each), or they can be dedicated to one function. The USB interface command rate is suitable for static positioning applications. Scanning applications should utilize the analog controller inputs or the High Speed Parallel interface.
