The Keysight (Agilent) 4395A provides excellent vector network, spectrum, and optional impedance measurements for lab and production applications. This versatile instrument combines gain, phase, group delay, distortion, spurious, CN, and noise measurements often required for evaluating components and circuits in a single unit.

When combined with a test set, the 4395A provides reflection measurements, such as return loss, SWR, and S parameters. As a vector network analyzer, the 4395A operates from 10 Hz to 500 MHz with 1 mHz resolution, and its integrated synthesized source provides -50 to +15 dBm of output power with 0.1 dB resolution.

The dynamic magnitude and phase accuracy are ±0.05 dB and ±0.3 degrees, enabling accurate measurement of gain and group delay flatness, which are increasingly important in modern electronics systems.
