8751A

Keysight Technologies (Agilent HP)Vector

The Keysight (formerly Agilent/HP) 8751A is a high-throughput, lab-precision vector network analyzer covering the 5 Hz to 500 MHz frequency range. It is designed for characterizing the linear behavior of passive and active networks, devices, and components in both laboratory and production test environments. The instrument features excellent resolution across frequency, magnitude, phase, and time domains, and supports full 2-port and interpolative calibration.
