Agilent/Keysight 8714C

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.
