Siglent SDG2122X 120MHz Function / Arbitrary Waveform Generator

The SIGLENT SDG2122X is a dual-channel function/arbitrary waveform generator with a 120 MHz maximum bandwidth, 1.2 GSa/s sampling rate and 16-bit vertical resolution. The proprietary TrueArb & EasyPulse techniques help to solve the weaknesses inherent in traditional DDS generators when generating arbitrary, square and pulse waveforms. With advantages above, SDG2122X can provide users with a variety of high fidelity and low jitter signals, which can meet the growing requirements of complex and extensive applications.

Excellent Analog Channel Performance

TrueArb Technology Architecture

With SIGLENT’s TrueArb technology, the generator retains the 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. Date points will not missed or repeated and arbitrary waveforms possess very low jitter (< 150ps).

Key Features:

Dual-channel, 120MHz maximum bandwidth, 20Vpp maximum
output amplitude, high fidelity output with 80dB dynamic range
High-performance sampling system with 1.2GSa/s sampling rate
and 16-bit vertical resolution. No detail in your waveforms will be
lost

High-performance Sampling System

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

Innovative EasyPulse Technology

When a Pulse waveform is generated by a common DDS generator, there will be a one-clock-jitter if the sampling rate is not an integer-related multiple of the output frequency. SDG1000X EasyPulse technology successfully overcomes this weakness in DDS designs and helps to produce low jitter Pulse waveforms.

Innovative TrueArb Technology

For arbitrary waveforms, TrueArb not only has all the advantages of traditional DDS, but also eliminates the probability that DDS may cause serious jitter and distortion.

The proprietary TrueArb & EasyPulse techniques help to solve the weaknesses inherent in traditional DDS generators when generating arbitrary, square and pulse waveforms. With advantages above, SDG2122X can provide users with a variety of high fidelity and low jitter signals, which can meet the growing requirements of complex and extensive applications.
