The HP/Agilent 70300A RF Tracking Generator is a 2-slot modular measurement system (MMS) module that provides stimulus-response measurement capabilities for RF systems. Operating as a slave device within the HP/Agilent 70000 Series architecture, it generates a calibrated RF output signal that precisely tracks both the frequency and amplitude of a connected spectrum analyzer. This tracking capability enables accurate characterization of gain, frequency response, isolation, and return loss across RF components and systems. The 70300A requires control from an HP 70900A/B local oscillator source and integrates with HP 71210A microwave spectrum analyzers and scalar measurement personalities for component and system analysis.
