PCI-344 PC Instruments Arbitrary Waveform Generator

The PC Instruments PCI-343/PCI-344 Arbitrary Waveform Generators occupy one PC expansion slot and combine the performance of advanced stand-alone generators with the convenience of the personal computer. Besides the features listed above, the PCI-343 and PCI-344 also provide 0.01% frequency accuracy, three selectable output filters, independent gain and offset controls, and software functions for nine standard waveform shapes. The single channel PCI-343 and the dual channel PCI-344 are both capable of pulses with 20 ns widths and 12 ns risetimes.

Powerful waveform memory control is a hallmark of these generators. The waveform memory can be divided into segments, with each segment having a different length and a different waveform. A waveform sequence can be created by linking segments together in any order, and each segment can be repeated up to 32767 times. Up to 16 waveform sequences can be created and switching between sequences can occur in as little as 20 ns. This extensive memory control makes it possible to create complex waveforms such as video test patterns, simulations of disk drive data, and encoded communication signals.
