選用二手測量儀器的優(yōu)勢是：
1、與新購儀器幾個月的供貨期相比，購買二手儀器的供貨期要短的多。在時間就是市場的今天，優(yōu)勢無疑是*為明顯的。
2、二手儀器的價格便宜，基本為新購儀器價格的20%～50%。在電子技術迅速發(fā)展的今天，儀器的更新也在加快，投資越少則風險越小。
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***計量測試單位進行校準。
Agilent 4395A 網(wǎng)路/頻譜/阻抗分析儀
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 reflectionmeasurements, such as return loss, SWR, and S parameters. As avector network analyzer, the Agilent 4395A operates from 10 Hz to500 MHz with 1 mHz resolution; and its integrated synthesizedsource provides -50 to +15 dBm of output power with 0.1 dBresolution. The dynamic magnitude and phase accuracy are ±0.05dBand ±0.3°. so that it can accurately measure gain and group delayflatness, which are becoming more important in modern electronicssystems.
As a spectrum analyzer, the 4395A operates from 10 Hz to 500 MHzwith resolution bandwidths (RBWs) spanning 1 Hz to 1 MHz in a1-3-10 steps. A fully-synthesized local oscillator allows stableand accurate frequency analysis. Direct A/D conversion (no LOGamplifier is used) results in ±0.8 dB level accuracy (@50 MHz, -20dBm). Noise sidebands fall below -100 dBc/Hz @ 100 kHz offset fromcarriers, while sensitivity is -145 dBm/Hz at 10MHz.
