SDG2000X Series
A dual-channel function/arbitrary generator with up to 120 MHz bandwidth, 1.2 GSa/s sampling and 16-bit resolution. Proprietary TrueArb and EasyPulse technologies deliver high-fidelity, low-jitter signals with a 20 Vpp output and a 4.3-inch touchscreen.
Overview
The SDG2000X series is a dual-channel function/arbitrary waveform generator. With up to 120 MHz bandwidth, a 1.2 GSa/s sample rate and 16-bit vertical resolution, it reconstructs waveforms accurately with low distortion.
Siglent's proprietary TrueArb and EasyPulse technologies solve the weaknesses inherent in traditional DDS generators: TrueArb plays arbitrary waveforms point-by-point without skipping, and EasyPulse produces low-jitter square and pulse waveforms with fine width and rise/fall control. A 20 Vpp output and an 80 dB dynamic range round out a versatile bench instrument.
Three models share identical performance and differ only in bandwidth: the SDG2042X (40 MHz), SDG2082X (80 MHz) and SDG2122X (120 MHz). Each provides a wide range of analog and digital modulation, sweep, burst, a high-precision frequency counter and 196 built-in arbitrary waveforms.
From R&D and education to communications and general signal simulation, the SDG2000X delivers high-fidelity, low-jitter signals from a single dual-channel instrument.
As the official Siglent distributor for Europe, we hold the SDG2000X in EU stock and back every unit with local warranty, optional ISO/DKD calibration and expert application support.
