The PCI-343 Single Channel Arbitrary Waveform Generator (AWG) and the PCI-344 Dual Channel Arbitrary Waveform Generator pack a lot of waveform generation capabilities into one PC expansion slot (ISA). These AWGs feature 50 MSPS update rate, 12 bits of resolution, 32 ksamples/channel (128 ksamples/channel is optional), and a memory controller that supports segmentation, sequencing, and looping. And, the Loop-Until-Triggered mode will repeat a segment until a new trigger event is detected. Also, the Multi-Sequence mode supports 16 different sequence tables that can be switched in as little as 20 ns, and multiple AWGs can be synchronized using the Master/Slave option.

50 MSPS - 12 Bits - 24 Vpp - Waveform Memory Sequencing - Looping - Memory Segmentation - Multi-Sequence Mode - DDS Clock

A Quadrature Amplitude Modulated signal (I and Q) is created by using the waveform sequencer of the PCI-344.

These AWGs have an outstanding list of analog features including output amplifiers with a 24 Vpp range, output filters, DC offset, reverse power protection, waveform summing, glitchless amplitude and offset changes, and short-circuit protected outputs. Complimenting the analog features are waveform memory control features not found on any other AWG including waveform memory segmentation, linking, looping, multi-sequence mode, and loop-until-triggered mode. Whether used to create digitally modulated communications signals (like the QAM signals pictured to the left), video signals, power line disturbance signals, stimulus signals for ATE systems, automotive sub-system simulation, or for general purpose testing, these AWGs are unmatched in their analog performance and waveform memory control capabilities. The PCI-343 and PCI-344 are one of the first generators to be interactive. Using the Multi-sequence mode, the AWG will respond to external patterns, symbols, or events, and respond by switching to a different waveform sequence. This mode is especially useful for creating digitally modulated waveforms. The pattern, symbol, or event can also originate from the PC. And, the Direct Digital Synthesis (DDS) clock circuit provides sample clock frequency resolution of 29 mHz and sample clock changes that are executed from the PC in as little as 10 us.
