The M4i.66xx-x8 series arbitrary waveform generators deliver the highest performance in both speed and resolution. The series includes PCIe cards with either one, two or four synchronous channels. The large onboard memory can be segmented to replay different waveform sequences.
The AWG features a PCI Express x8 Gen 2 interface that offers outstanding data streaming  performance. The interface and Spectrum’s optimized drivers enable data transfer rates in excess of 2.8 GB/s** so that signals can be continuously replayed at a high output rate.
While the cards have been designed using the latest technology they are still software compatible with the drivers from earlier Spectrum waveform generator cards.
