The V350 is a 4-channel VME analog/digital function generator that generates arbitrary waveshapes synchronized with logic-level outputs, as might be used in control systems or radar simulation, or other COTS applications.
Each V350 channel generates one 12-bit analog waveform and up to four digital outputs by scanning sequential data points stored in user-loadable memory. Outputs are processed by digital-to-analog converters, smoothing filters, and output amplifiers.
Output stage multiplexing allows flexible configuration, and channels may operate independently or may be synchronized within a module or across modules.
Control and waveform generation operate at full 40-MHz rate or programmed sub-multiples. An option allows waveform generation synchronous to an external trigger without the jitter resulting from quantization to the local clock.
Each channel has 1 Mword of waveform memory controlled through a 512-block command table that includes Play, Delay, Wait, and Stop commands, conditional jump, and flag control.
Self-test and Demo modes allow quick evaluation and verification.
