The Keysight 71200A RF Spectrum Analyzer measures signal magnitude across a range of frequencies, enabling detailed analysis of radio frequency spectrum characteristics. This legacy instrument visualizes RF signals and examines frequency, amplitude, modulation, and distortion parameters. As an obsolete product, direct manufacturer support is no longer available; however, self-support resources remain accessible through Keysight’s website.
Technical Specifications
The 71200A belongs to the modular 70000 series architecture, which employed system building blocks for RF and microwave measurements. The analyzer performs fundamental magnitude-versus-frequency measurements, with capabilities extended through optional modules including preamplifiers and external mixers.
Frequency coverage spans the RF spectrum; related 70000 series models operated from 100 Hz to 29 GHz (71100C RF Spectrum Analyzer) and 50 kHz to 22 GHz (71200C Microwave Spectrum Analyzer), providing context for the 71200A’s measurement band.
– Key Features
• Modular system architecture enabling customized test system configuration
• Signal amplitude measurement for power and voltage level analysis
• Frequency identification and signal characterization
• Analysis of modulation, distortion, and spurious emissions
• Expandable measurement capability through optional preamplifiers and external mixers
– Compatibility & Integration
The 70000 series supported standard test and measurement interfaces of its era, including GPIB (IEEE-488) for instrument control and data transfer. Ethernet/LAN compatibility was commonly available as a configurable option on modular systems of this generation.
– Typical Applications
RF signal characterization, spectrum visualization, modulation analysis, and spurious emission detection across RF measurement domains.
