Two Channel High Voltage Interface

  • USB or RS232 interface
  • C++ code examples (all required libraries included)
  • Compact and simple to use
  • Microsoft® HyperTerminal configuration file included
  • Independent control of voltage levels on two channels to 10 mV resolution
  • Includes National Instruments LabVIEW™ Virtual Instrument drivers to interface with custom software

Our two Channel High Voltage Digital Interface is designed for independent high precision computer control of up to two Meadowlark Optics Swift LC liquid crystal devices at one time.
The D3060HV Package includes all the functionality of the D3050 plus the high voltage circuitry necessary for Swift LC devices. Also included is capability for temperature monitoring and control on one channel. The Advanced Package allows the amplitude of the 13 kHz square wave output to be driven either by an external 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.
