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

Agilent / 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 4395A provides reflection measurements, such as return loss, SWR, and S parameters. As a vector network analyzer, the 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 4395A operates from 10 Hz to 500 MHz with resolution bandwidths (RBWs) spanning 1 Hz to 1 MHz in a 1-3-10 steps. A fully-synthesized local oscillator allows stable and accurate frequency analysis. Direct A/D conversion (no LOG amplifier is used) results in +/-0.8 dB level accuracy (@50 MHz, -20 dBm). Noise sidebands fall below -100 dBc/Hz @ 100 kHz offset from carriers, while sensitivity is -145 dBm/Hz at 10 MHz.

New Approach to Electronic Component and Circuit Evaluation

A new concept in testing that combines the power of a vector network analyzer, a spectrum analyzer, and an optional impedance analyzer.

Take an innovative approach to evaluating electronic components and circuits. The Agilent Technologies combination analyzers family combines three analyzer functions in one powerful instrument: a vector network analyzer, a spectrum analyzer, and an optional impedance analyzer. Now you can use one analyzer for multiple testing needs.

Because many electronic components such as amplifiers require both vector network and spectrum parameters, you need a combination analyzer to meet new testing requirements such as:

• Measuring intermodulation distortion and phase performance of components used in digital communication systems.
• Characterizing monolithic ICs or circuit blocks.

Compared with using separate analyzers, you save equipment cost and bench space with the Agilent 4395A/96B, and avoid time-consuming and messy signal cabling to multiple instruments.
