Signal Oscillator

A signal oscillator is an electronic component that generates periodic electrical signals at specific frequencies. Within a Probe Generator, this oscillator produces stable, precise oscillating signals that serve as the fundamental timing or reference source for the probe's measurement and detection functions. It ensures consistent signal generation for accurate data acquisition. The oscillator is designed for use in computer, electronic, and optical product manufacturing, where it functions as a component-level part. It is typically integrated into larger systems, such as probe generators, to provide a reliable frequency reference. The device operates by converting DC power into AC signals through controlled amplification and phase shift, using feedback mechanisms such as LC, RC, or crystal-based circuits. Key parameters include a frequency range of 1–100 MHz (custom frequencies available on request), frequency stability of ±10 ppm over -20 to 70 °C, adjustable output power from 0–10 dBm, supply voltage of 3.3–5 V DC, supply current of 20–50 mA at 5 V DC, operating temperature range of -20 to 70 °C (extended range optional), phase noise of -120 dBc/Hz at 10 kHz offset, output impedance of 50 Ω, harmonic suppression of -30 dBc (second harmonic), pulling range of ±100 ppm with 10 kΩ load, pushing figure of ±5 ppm/V, and dimensions of 14.2×9.8×5.5 mm in an SMD package. Materials used include quartz crystal, semiconductor components (transistors/ICs), ceramic capacitors, and copper conductors. These specifications are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. The oscillator is not a standalone product but a component intended for integration into larger electronic systems. It is important to confirm compatibility with the target system's requirements, including frequency, power, and environmental conditions. The directory does not manufacture or sell this product; it provides neutral information for procurement and verification purposes.

The signal oscillator uses electronic circuits with feedback mechanisms, such as LC, RC, or crystal-based oscillators, to sustain continuous oscillations at a predetermined frequency. It converts DC power into AC signals through controlled amplification and phase shift. The feedback loop ensures that the oscillator maintains a stable output frequency despite variations in supply voltage or temperature. The specific circuit topology determines the frequency stability and phase noise characteristics. For example, crystal-based oscillators offer high frequency stability, while LC oscillators are suitable for higher frequencies. The oscillator's output is typically buffered to drive a 50 Ω load, and its frequency can be adjusted within a specified range. The working principle is fundamental to generating precise timing signals for measurement and detection applications.
