HP-Agilent/Keysight 4195A

500 MHz Network/Spectrum Analyzer 4195A is a high-performance, cost-effective, and intelligent analyzer with combined vector network and spectrum analysis capabilities. The frequency is covered from 10 Hz through 500 MHz with an excellent 0.001 Hz resolution for audio, baseband, HF, VHF, and IF applications. It directly measures amplitude ratio, phase, group delay, and spectrum level needed for characterizing linear/non-linear analog circuits or components used in communications, telecommunications, consumer electronics, and other equipment.
