DBS8750 Analogic High Precision Arbitrary Waveform Synthesizer

The DBS 8750 is a high speed (400 kHz), 16-bit, precision, dual channel Arbitrary Waveform Synthesizer. Fully compatible with VXI specification Rev. 1.3, the DBS 8750 occupies a single “C” size slot in a VXI chassis. Highly accurate standard and arbitrary waveforms are generated for use in a variety of demanding applications such as acoustical signatures, vibration analysis, complex signal generation, automatic test equipment, linear device testing, digital communications, and biomedical signal simulation.

Combining the superior performance of a dual digital-to-analog converter (DAC), with a 100 dB dynamic range, and the speed and processing capability of the TMS320C30 digital signal processor (DSP), the DBS 8750 provides precise, direct digital synthesis (DDS) of analog signals at an economically attractive price.

For maximum flexibility, three sources of digital data are supported for arbitrary waveform generation and signal processing: downloaded data from VXI-resident memories, calculated data from the resident DSP, and local bus transferred data via connector P2 from other adjacent cards such as the Analogic DBS 87xx family of VXI digitizer modules.

This multiple sourcing of waveform data, complemented by versatile triggering and cross-synchronization capabilities, allows easy integration of precision analog signal synthesis within sophisticated VXI instrumentation applications. Software integration effort is reduced to an absolute minimum with the DBS 8750. Message-based device architecture allows serial word communication protocols with any Slot 0 Controller using Standard Commands for Programmable Instruments (SCPI).
