What are the Analog Output Converter Cards?

Concurrent’s CP-DA3218 is a 32-channel or 8-channel, 18-bit digital-to-analog converter card with a PCI express interface. The card is implemented using Linear Technology LTC2758 dual channel DACs. All output ranges are selectable on a per channel basis. The synchronous conversion clock source is generated by a low jitter PLL. Differential or single-ended outputs are supported via build options. Multi-board synchronization is supported with simple RJ-style cabling. NIST traceable calibration is included with all boards. A RedHawk™ Linux® driver with extensive API including DMA and interrupts is available for both 32-bit and 64-bit architectures.

In addition, an optional wave generation package is available that provides an easy, yet powerful mechanism for users to generate continuous and unique usersupplied waveforms on any specifed channels of the card.
