The Agilent/Keysight 8714C is an economy RF vector network analyzer engineered for high-volume manufacturing, inspection, and maintenance of RF components. Operating from 300 kHz to 3 GHz, it delivers simultaneous dual-channel measurement and display with integrated synthesized source and transmission/reflection test set. A single connection enables comprehensive swept-frequency characterization of RF components with 50 ms/sweep speed and up to 100 dB system dynamic range. The instrument supports multiple measurement formats—rectilinear, phase, group delay, Smith Chart, polar, and specialized broadband modes—with error term correction for improved accuracy. Internal 9-inch display and VGA interface enable flexible monitoring, while dual independent channels support single, overlay, and split-screen modes with eight markers per channel. Data storage via 3.5-inch disk drive accommodates 20 instrument states and multiple formats including MS-DOS, binary, ASCII, and graphics output. GPIB (IEEE 488.2, SCPI), RS-232C, Centronics, and optional TCP/IP Ethertwist LAN with FTP ensure flexible integration into test environments.
