The ProDAQ 3550 Fast Digital-to-Analog Converter & Arbitrary Waveform Genera-tor Function Card provides two channels per card, each equiped with a 16-bit, fast and precision Digital-to-Analog Converter, 2-pole analog filter and 256k x 16 SRAM memory per channel. Eight unipolar and four bipolar output voltage options are available.

The ProDAQ 3550 can be used as a two-channel Waveform Generator. Two user defined waveforms, stored in two 256k x 16 SRAMs, can be created with an update time ranging from DC to 1s (1MHz). 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 a larger SRAM is required the FDAC can be configured as a single-channel, dual output DAC with 512k SRAM.

Several trigger modes are available for synchronization purposes. Complex wave- forms are accompanied with powerful trig-ger output signals to mark the events inside the waveforms.

The 2-pole analog filter (Sallen-Key type) provides four, software-selectable, cutoff frequencies. A filter bypass mode can also be selected.

The output buffer provides necessary gain and output power. Depending on the fitted-in components, it works either as an inverting or non-inverting amplifier. Software-controlled calibration process au-tomatically removes offset and gain er-rors providing unprecedented accuracy re-quired for demanding DC and low fre-quency applications. Initial accuracy in this type of application is 100ppm.

The FDAC function card will be equipped with either 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 con-tact resistance.
