Units produce stable and precise sine, square, triangle, pulse and arbitrary waveforms with 16-bit vertical resolution. Product’s dual architecture design combines the cost-saving benefits of DDS and true point-by-point arbitrary performance to meet a wide range of applications. A sample rate of up to 300MSa/s in DDS mode or 75MSa/s in true arbitrary mode, allows users to create high-fidelity custom arbitrary waveforms with up to 8 million points in length without skipping data points. Unit’s convenient touchscreen display simplifies configuration and control over many features including sweep, burst, and waveform modulation functions. Other standard features include a built-in frequency counter and 10 MHz reference clock input/output to synchronize multiple instruments.
