Signal Source

The signal source is a critical component within a network analyzer that produces stable, calibrated electrical signals across specified frequency ranges. It serves as the reference input for measuring the response characteristics of devices under test, enabling analysis of parameters such as scattering parameters (S-parameters), impedance, and transmission characteristics. This directory entry describes a generic signal source component intended for integration into network analyzer systems. The component is designed to operate within a frequency range of 9 kHz to 6 GHz, with a frequency resolution of 0.01 Hz, allowing fine tuning for narrowband signals. Its output power range spans from -120 dBm to +10 dBm, with an accuracy of ±0.5 dB, ensuring reliable amplitude calibration. Phase noise is specified at -110 to -90 dBc/Hz at a 10 kHz offset, and harmonic distortion is less than -30 dBc, contributing to clean signal generation. The switching speed is 100 microseconds for fast frequency and amplitude settling. The component operates within a temperature range of 0 to 50 °C, with storage from -40 to 70 °C. It requires a supply voltage of 100-240 V AC and consumes no more than 50 W. Physical dimensions are 450 mm × 150 mm × 400 mm (W×H×D), and it weighs 8 kg. Interfaces include USB, LAN, and GPIB for remote control and automation. The signal source typically employs frequency synthesis techniques such as phase-locked loops (PLLs) or direct digital synthesis (DDS) to generate precise sinusoidal waveforms. It includes amplification stages to achieve required power levels and modulation capabilities for complex signal generation. The output is precisely controlled in frequency, amplitude, and phase to serve as a reference for network analysis measurements. Materials used include semiconductor components (transistors, diodes), ceramic substrates, copper conductors, and ferrite materials.
