The Keysight (Agilent) 70301A is a microwave tracking generator operating from 2.7 to 18 GHz, engineered to synchronize with compatible spectrum analyzers for precise frequency response characterization of RF and microwave devices. By tracking the local oscillator frequency of the connected analyzer, it delivers a stimulus signal matched to the measurement frequency, enabling rapid swept measurements of filters, amplifiers, and similar components across the microwave band.

– Key Features
• Tracks spectrum analyzer local oscillator for synchronized stimulus generation
• Supports single sweep, continuous sweep, and manual step modes controlled by the analyzer
• Variable resolution bandwidth capability through spectrum analyzer RBW control
• External and internal triggering options via spectrum analyzer interface
• Low harmonic and spurious content enables clean component characterization
– Typical Applications
• S-parameter measurements of microwave filters and amplifiers
• Frequency response analysis of RF networks
• Gain and insertion loss verification across 2.7–18 GHz band
• Swept gain and return loss measurements synchronized with analyzer detection
– Compatibility & Integration
Designed as a plug-in module or integrated system component for Keysight spectrum analyzer mainframes. Primary compatibility includes the 8560 and 8570 Series. Frequency tracking and operational control are established through dedicated control cables interfacing with the host analyzer’s local oscillator and command structure. Power requirements and physical dimensions are determined by the host mainframe.
