Characteristics
High-performance Sampling System
Benefiting from a 1.2GSa/s and 16-bit sampling system, SDG2000X achieves extremely high accuracy performance in bothtime domain and amplitude, which results in more accurately reconstructed waveforms and lower distortion.

Excellent Analog Channel Performance

The bandwidth of analog channels proves to be greater

Innovative EasyPulse Technology

When a Square/Pulse waveform is generated by DDS, there will be a one-clock-jitter if the sampling rate is not an integerrelated multiple of the output frequency. SDG2000X EasyPulse technology successfully overcomes this weakness in DDS
designs and helps to produce low jitter Square/Pulse waveforms.
