Key benefits Accurate, stable frequency reference: crystal-based digital oscillator provides reliable timing and frequency output to reduce drift and maintain measurement accuracy. High resolution and control: DDS algorithm allows fine frequency steps down to 0.001 Hz for precise adjustment and repeatable results. Improved interference immunity: solid-state crystal reference and digital design reduce susceptibility to external noise and help maintain signal integrity in cluttered environments. Versatile use: built to deliver a fixed 7.830 Hz output or act as a fully programmable signal source from 0.001 Hz to 200 kHz, replacing or supplementing standard signal generators. What this product solves Eliminates frequency drift and unstable references that compromise test, measurement, and timing tasks. Provides precise, repeatable frequency increments for calibration, research, and development where small changes matter. Reduces the need for multiple signal sources by serving both as a dedicated 7.830 Hz reference and a general-purpose programmable digital signal generator. Key features and performance Digital crystal oscillator frequency reference for enhanced stability and anti-interference performance. DDS (Direct Digital Synthesis) algorithm enabling frequency step resolution of 0.001 Hz. Factory-capable output of 7.830 Hz plus programmable frequency modulation across 0.001 Hz to 200 kHz. Can function as a standard programmable digital signal generator for a wide range of applications. Compatibility and use Integrates with test and measurement setups that accept external frequency references or digital signal generator inputs. Suitable for use with control systems, development boards, bench instruments, and lab equipment that require a stable, precise frequency source. No special materials or form factors are required beyond typical electrical connections for signal output and power (refer to your system’s input requirements). Practical applications (examples) Laboratory calibration and research: Use as a stable reference for frequency measurements, sensor characterization, and instrument calibration where fine frequency adjustment is required. Electronics development and testing: Use the programmable output as a low-frequency reference (7.830 Hz) or to generate test signals up to 200 kHz for troubleshooting, waveform generation, and timing tests. Educational and prototyping environments: Provide students and engineers with a reliable, easy-to-program frequency source for experiments, LFO tasks, and control-system testing.
