The ProDAQ 3550 fast DAC and arbitrary waveform generator function card provides two channels per card, each equipped with a 16-bit fast and precise DAC 2-pole analog filter and 256k x 16 SRAM memory per channel, with several standard output ranges available. The ProDAQ 3550 can be used as a two-channel waveform generator; the memory can be divided into segments to store complex waveforms. Segments not currently used in a waveform can be loaded during running bursts, providing higher data throughput.
If users require larger SRAM, they can configure the ProDAQ 3550 as a single-channel, dual-output DAC with 512k SRAM. Several trigger modes are available for synchronization purposes. The 2-pole analog filter (Sallen-Key type) provides three software-selectable cutoff frequencies, and users can also select filter bypass mode. The output buffer provides necessary gain and output power and a software-controlled calibration process automatically removes offset and gain errors, providing unprecedented accuracy required for demanding DC and low-frequency applications.
The ProDAQ 3550 function card is equipped either with a high-density SCSI-type connector or five LEMO connectors. In the case of the SCSI-type connector, four pins will be dedicated to each output to minimize contact resistance.
