The SA201 is specifically designed to control Thorlabs SA200 Series Fabry Perot Interferometers. The controller generates a voltage ramp, which is used to scan the separation between the two cavity mirrors. The controller provides adjustment of the ramp voltage and scan time, allowing the user to choose the scan range and speed. An offset control is provided to allow the spectrum displayed on the oscilloscope to be shifted right or left. Another convenient feature of the controller is a zoom capability that provides a 1X, 2X, 5X, 10X, 20X, 50X and 100X increase in the spectral display resolution. The ouput TTL level trigger allows the user to externally trigger an oscialloscope on either the beginning or midpoint of the ramp waveform.
