Four Channel Digital InterfaceKey Features
- USB or RS232 interface
- Independent control of voltage levels on four channels to 1 mV resolution
- Includes National Instruments LabVIEW™ Virtual Instrument drivers to interface with custom software
Our Four Channel Digital Interface is designed for high precision computer control of up to four Meadowlark Optics nematic liquid crystal devices at one time. The interface comes with software to allow independent control of the amplitude of the 2 kHz square wave drive for four separate nematic liquid crystal cells. Additionally, the Interface also provides the capability for temperature monitoring and control on one channel. The amplitude of the 2 kHz square wave output can be driven by either an external DC analog signal supplied to a front panel connector or specific CellDRIVE generated waveforms including sinusoidal, square, triangle, sawtooth and transient nematic effect waveforms. Additional functions include the capability to output a sync pulse on a front panel connector at desired points in the CellDRIVE generated waveforms and the ability to save/restore all CellDRIVE settings to/from a file.
