選用二手測(cè)量?jī)x器的優(yōu)勢(shì)是：
1、與新購儀器幾個(gè)月的供貨期相比，購買二手儀器的供貨期要短的多。在時(shí)間就是市場(chǎng)的今天，優(yōu)勢(shì)無疑是最為明顯的。
2、二手儀器的價(jià)格便宜，基本為新購儀器價(jià)格的20%～50%。在電子技術(shù)迅速發(fā)展的今天，儀器的更新也在加快，投資越少則風(fēng)險(xiǎn)越小。
3、為了讓您放心地使用我們提供的二手儀器，我們銷售的二手儀器可以做到：
1、保修半年至一年不等。
2、可以根據(jù)您的要求，將儀器送至國家級(jí)計(jì)量測(cè)試單位進(jìn)行校準(zhǔn)。
The 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 Agilent 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 ±0.05dB and ±0.3°. 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.
