Siglent's SDG2000X is a series of dual-channel function/arbitrary waveform generators with specifications of up to 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, SDG2000X can provide users with a variety of high fidelity and low jitter signals, which can meet the growing requirements of complex and extensive applications. Features Dual-channel, 40 MHz 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. Innovative TrueArb technology, based on a point-by-point architecture, supports any 8pts~8Mpts Arb waveform with a sampling rate in range of 1μSa/s~75MSa/s. Innovative EasyPulse technology, capable of generating lower jitter Square or Pulse waveforms, brings a wide range and extremely high precision in pulse width and rise/fall times adjustment. Plenty of analog and digital modulation types: AM, DSB-AM, FM, PM, FSK, ASK and PWM. Sweep and Burst functions. High precision Frequency Counter. Standard interfaces: USB Host, USB DeviceUSBTMC, LAN (VXI-11) Optional interface: GPIB. 4.3” touch screen display for easier operation. Specifications Maximum output frequency 40 MHz Output channels 2 Sampling rate 1.2 GSa/s (4X Interpolation) Wave length CH1: 16 Kpts, CH2: 512 Kpts Frequency resolution 1 μHz Vertical resolution 16 bit Standard interfaces Standard interfaces: USB Host, USB Device (USBTMC), LAN (VXI-11) 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 Square/Pulse waveform is generated by DDS, there will be a one-clock-jitter if the sampling rate is not an integer-related multiple of the output frequency. SDG2000X EasyPulse technology successfully overcomes this weakness in DDS designs and helps to produce low jitter Square/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. Easy controll with 4.3” Touch Screen Display and Arbitrary Waveform Software EasyWave The 4.3” touch screen display, makes operation much more convenient. And EasyWave is a powerful arbitrary waveform editing software that supports several ways to generate arbitrary waveform such as manual drawing, line-drawing, equation-drawing, coordinate-drawing, etc. It is quite convenient for users to edit their own arbitrary waveforms through EasyWave. Included Siglent SDG2042X Arbitrary Function Generator User Manual Guarantee Card CD (including EasyWave 1.0 computer software system) Power Cord USB Cable Quick Start Guide
