Technical details and manufacturing context for Tracking Generator

Definition
A tracking generator is a specialized signal generator component integrated with or used alongside a spectrum analyzer. It produces a test signal whose frequency precisely follows the analyzer's sweep frequency, enabling measurement of device frequency response, insertion loss, and return loss by comparing the input and output signals.
Working Principle
The tracking generator receives a frequency reference signal (typically a local oscillator signal) from the spectrum analyzer's sweep circuitry. It uses this reference to generate a stable, calibrated RF output signal that is locked to and tracks the instantaneous frequency being analyzed. This allows for stimulus-response measurements where the device under test receives the tracking generator's signal, and the spectrum analyzer measures the output.
