The Keysight (Agilent) 8751A Network Analyzer delivers lab-grade precision across a frequency range of 5 Hz to 500 MHz, supporting full 2-port and interpolative calibration. With 0.001 Hz frequency resolution, 0.001 dB amplitude, 0.001° phase, and 10 ps time resolution, it characterizes linear behavior of active and passive devices with high accuracy. It features ±0.02 dB/±0.12° dynamic accuracy, 10 updates of 201 points/sec, and 0.4 ms/point fast list sweep. The built-in 1.44 MB floppy drive allows saving instrument states, calibration data, and custom programs.
Ideal for production and lab environments, the 8751A enables multi-trace measurement with up to four simultaneous displays and includes test sets for 50/75 Ω S-parameters and T/R configurations.
Testwall can supply the used Keysight (Agilent) 8751A, fully tested.
