M4i.96xx Series

The M4i.96xx-x8 series DDS generators deliver the highest performance in both speed and resolution. The series includes PCIe cards with either one, two or four synchronous channels. DDS – Direct Digital Synthesis – is a method for generating sine waves from a single, fixed-frequency reference clock and is widely used in signal generation applications. The DDS functionality implemented on Spectrum Instrumentation’s AWG platform is based on the principle of adding multiple “DDS cores” to generate a multi-carrier (multi-tone) signal, with each carrier having its own well-defined frequency, amplitude and phase. In addition to these static parameters, there are also build in dynamic parameters like frequency slope and amplitude slope to allow for intrinsic linear changes for multiple cores.
