NI launches suite of 100 mega-samples per second, mixed-signal PXI instruments National Instruments has introduced a suite of 100 mega-samples per second (MS/s) PXI instruments that can be used in the rapid prototyping and testing of mixed-signal devices and systems. The modular products include four new instruments, including 100 and 50MHz digital waveform generator/analysers, a 100MS/s 16-bit arbitrary waveform generator, and a 100MS/s 14-bit high-resolution digitiser.
