Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few waveform generator, arbitrary waveform generator manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom waveform generators, arbitrary waveform generators has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

Uses direct digital-synthesis techniques. Creates stable, accurate output signal for low distortion sine waves. Gives you square waves with fast rise and fall times. Software enables you to create, edit and download complex waveforms. One-Year Warranty. 10 Standard waveforms, with sine and square to 20 MHz Arbitrary waveforms at 50 MSa/s Clean signals: THD less than 0.04% and flatness as low as ±0.1dB The Agilent 33220A function/arbitrary waveform generators give you 10 standard waveforms and the ability to create versatile arbitrary waveforms, with 12-bit resolution and a sample rate of 50 MSa/s. In addition, they can generate pulse waveforms with variable edge time. The optional 001 external clock-reference timebase increases the frequency stability while letting you generate precise phase-offset signals, phase-lock to another generator, or to a 10MHz frequency standard. One-Year Warranty. Model: 33220A Frequency Range: 20 MHz Standard Waveforms: Sine, square, pulse, triangle, ramp, noise, sin(x)/x, exponential rise and fall, cardiac, dc volts Arbitrary Waveforms: 1 to 64 K-points Sample Rate: 50 MSa/s.
