HP 4395A Network/Spectrum/Impedance Analyzer, 10 Hz to 500 MHz

The HP 4395A provides excellent vector network, spectrum, and optional impedance measurements for lab and production applications. Gain, phase, group delay, distortion, spurious, CN, and noise measurements often required for evaluating components and circuits can be measured using one instrument.

When combined with a test set, the HP 4395A provides reflection measurements, such as return loss, and SWR, and S parameters. As a vector network analyzer, the HP 4395A operates from 10Hz to 500MHz with 1 mHz resolution; and its integrated synthesized source provides -50 to + 15dBm of output power with 0.1 dB resolution. The dynamic magnitude and phase accuracy are ±0.05dB and ±0.3deg. so that it can accurately measure gain and group delay flatness, which are becoming more important in modern electronics systems.

As a spectrum analyzer, the HP 4395A operates from 10Hz to 500MHz with resolution bandwidths (RBWs) spanning 1Hz to 1MHz in a 1-3-10 sequence. A fully synthesized local oscillator allows stable and accurate frequency analysis. As a impedance analyzer by the addition of Option 010 and test kit, the HP 4395A operates from 100kHz to 500MHz with Z basic accuracy: 3% (typical).
