The Agilent/Keysight 8711A is a scalar network analyzer that combines a synthesized source, transmission/reflection test set, and CRT display in a single integrated instrument. It delivers fast, accurate RF component characterization from 300 kHz to 1.3 GHz with 50 ms sweep speed and up to 100 dB system dynamic range. Built for high-volume manufacturing and production test environments, the 8711A simplifies setup through HP Instrument BASIC automation and keystroke recording while maintaining precision across gain, loss, return loss, SWR, and conversion loss measurements.

– Typical Applications
• RF component manufacturing and characterization
• Production-line testing of narrowband and broadband devices
• Gain and loss measurement across UHF and lower-microwave frequencies
• SWR and return loss validation in 50 Ω and 75 Ω systems
– Compatibility & Integration
The 8711A pairs with IBM-compatible PCs via DOS-formatted disk storage and supports optional DIN keyboard input. Calibration standards for Type-N connectors (both 50 Ω and 75 Ω) and external detectors enable remote device measurements. Optional rack mount kit (1CM) and soft carry case (1CF) accommodate varied deployment scenarios.
