The Agilent / HP 4395A is a highly integrated 10 Hz to 500 MHz combination analyzer providing exceptional vector network, spectrum, and optional impedance measurements in a single instrument. With direct A/D conversion and a fully-synthesized local oscillator, it offers fast and accurate evaluation of gain, phase, group delay, distortion, spurious responses, and noise for lab and production environments.
