Technical details and manufacturing context for Reference Signal Generator

Definition

The Reference Signal Generator is a component used within calibration systems to produce precise electrical signals with known amplitude, frequency, and waveform characteristics. It serves as a benchmark for calibrating measurement instruments, testing electronic equipment, and verifying system performance by providing a reliable standard against which other signals can be compared. The device generates stable base frequencies using quartz crystal oscillators or atomic frequency standards, which are then processed through frequency synthesizers, amplifiers, and modulation circuits to produce various output signals. Signal integrity is maintained through temperature compensation, shielding, and feedback control mechanisms. The generator is housed in an aluminum alloy enclosure and uses copper conductors, silicon semiconductors, and ceramic substrates. Key parameters include an output frequency range of 0.1–20 MHz, frequency accuracy of ±1×10⁻⁶, output amplitude range of 0.1–5 Vpp into 50 Ω, amplitude accuracy of ±0.5 dB at 1 kHz, harmonic distortion below -40 dBc, phase noise of -120 dBc/Hz at 10 kHz offset, and output impedance of 50 Ω. It operates over a temperature range of 0–50 °C and can be stored at -20–70 °C with non-condensing humidity of 20–80% RH. Power supply is 100–240 V AC, 50/60 Hz, with typical power consumption ≤30 W. Dimensions are 210×88×300 mm (W×H×D) and weight ≤3 kg. This directory entry provides reference values; actual model-specific values and standards must be verified with the legal manufacturer or supplier.

Working Principle

The device uses a quartz crystal oscillator or atomic frequency standard to generate a highly stable base frequency. This signal is then processed through frequency synthesizers to produce the desired output frequency, followed by amplifiers and modulation circuits to set amplitude and waveform. Temperature compensation and shielding minimize environmental effects, while feedback control mechanisms ensure output stability and accuracy.
