Spectrum M4x series PXIe arbitrary waveform generators

The Spectrum M4x series PXIe arbitrary waveform generators provide an automated testing application that requires fast and accurate electronic signal generation. Based on the modular instrumentation standard, the product includes five new modules that provide one, two or four channels.

Each channel is equipped with 16-bit digital-to-analog converter (DAC) technology. The various models have maximum clocking rates of 625 MS/s or 1.25 GS/s. The combination of high resolution and fast clocking rates makes them suitable for generating precise and flexible wave shapes with frequency content from DC to 400 MHz.

The product features a XIe x4 Gen 2 interface that allows waveform data to be transferred to the 4 GB of onboard memory, at speeds up to 1.4 GBps. Fully PXIe compliant, the modules can be used in any PXIe or PXI hybrid chassis. Support is also provided for chassis distribution features such as the PXIe/PXI reference clock, star-trigger and trigger bus.

The product includes a number of operating modes such as single-shot, loop, FIFO, gating and sequence replay. In FIFO mode, the instruments can stream data continuously from PC memory over the PXIe interface. The product can also output signals while new waveform data is being sent to the onboard memory.
