Versatile Multi-Functionality
The JDS2900 DDS Signal Generator combines a variety of functions in one device, making it an essential tool for electronics engineers, laboratories, and educational institutions. It integrates features such as a Function Signal Generator, Arbitrary Waveform Generator, Pulse Generator, Sweep Generator, Counter, and Frequency Meter. -
Stable and Precise Signal Generation
Utilizing Direct Digital Synthesizer (DDS) technology, this instrument provides stable, precise, pure, and low distortion signals. Whether you're testing, measuring, or conducting research, this signal generator ensures accurate and reliable performance for all your electronic applications. -
Dual-Channel with Independent Control
Featuring a dual-channel output, the JDS2900 allows you to generate independent signals on each channel. You can easily adjust each channel's frequency, amplitude, and duty cycle independently, with phase difference continuously adjustable from 0° to 359.9°. This feature is ideal for applications that require two synchronized signals or completely independent outputs. -
Advanced Waveform Customization
The generator can reproduce custom waveforms, offering 60 groups of arbitrary waveform storage with a memory depth of 2048*14bits for each group. This allows you to store and recall complex waveforms for efficient testing. -
Precise Frequency and Amplitude Control
With a frequency resolution of 0.01uHz and a high amplitude resolution (1mV), the JDS2900 ensures that you can fine-tune your signals to match the exact specifications required for your test scenarios. The frequency range extends from 1Hz to 100MHz, and the amplitude range spans from 2mVpp to 20Vpp, covering a wide variety of testing needs. -
Sweep and Trigger Functions
The sweep function offers both linear and logarithmic sweep modes, with a sweep time range from 0.1s to 999.9s. Additionally, the generator supports four trigger modes and a pulse width adjustment range from 25ns to 4000s, allowing for flexible signal control. -
PC-Controlled and Communication Features
For ease of use, this signal generator can be controlled via PC software using the provided communication protocol. You can also generate arbitrary waveforms and perform secondary development programming with the software, enhancing the instrument’s versatility for advanced users. -
Additional Protective Features
Equipped with output short-circuit protection, the JDS2900 can safely operate for up to 60 seconds under load short-circuit conditions, ensuring the safety and longevity of the device and your connected equipment.
