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)勢無疑是最為明顯的。
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(shù)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，將儀器送至國家級計量測試單位進行校準。
The R3131A offers a 9 kHz to 3 GHz frequency range, meeting the frequency needs of both PCS and cellular wireless standards. The synthesized architecture and specifications such as phase noise lower than -100 dBc/Hz @ 20 kHz offset, ensure measurement accuracy and repeatability. This level of accuracy, plus one-button automated measurements for adjacent channel power, occupied bandwidth, and average and total power, make the R3131A a great choice for wireless design and troubleshooting. The R3131A also provides automatic pass/fail limit testing, great for manufacturing applications.
