Siglent SDG2042X
Function Arbitrary Waveform Gen

Professional Waveform Generator

SDG series is dual-channel function/arbitrary waveform generator with a bandwidth of up to 120MHz, 1.2GSa/s sampling rate and 16-bit vertical resolution. The proprietary TrueArb & EasyPulse technologies help to solve the weaknesses inherent in traditional DDS generators when generating arbitrary, square and pulse waveforms.

TrueArb Technology Architecture
With Siglent’s TrueArb technology, the generator retain advantages of DDS technology while overcoming the serious weaknesses of DDS jitter and distortion. Because TrueArb technology generates arbitrary waveform in a point-by-point fashion, every data point is used to generate the output signal which has been stored in memory. TrueArb technology produces an arbitrary point-by-point waveform. Don't miss any details!
High-Performance Sampling System
Benefiting from a 1.2GSa/s and 16-bit sampling system, the SDG2042X achieves extremely high accuracy performance in both time domain and amplitude. resulting in a more accurate, reconstructed waveforms with lower distortion.
Excellent Analog Channel Performance
The bandwidth on the analog channels proves to be greater than 120MHz, tested by doing a frequency response test with white noise.
Rich modulation features
Support for AM, FM, PM, FSK, ASK, DSB. AM provides a variety of analog and digital modulation mode, "internal" and "external" modulation.
