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 R&S®SMU200A has been designed to meet all requirements encountered in research and development of modern communication systems as well as in their production. The R&S®SMU200A Vector Signal Generator not only combines up to two independent signal generators in one cabinet of only four height units, it also offers unrivalled RF and baseband characteristics.

Two signal generators in one

• Frequency options from 100 kHz to 2.2/3/4/6 GHz for the first RF path
• Optional second RF path up to 2.2 GHz or 3 GHz
• Up to two complete baseband paths
• Lossless combination of baseband signals in the digital domain (e.g. for testing multistandard base stations)
  
  Outstanding signal quality
• I/Q modulator with 200 MHz RF bandwidth
• Very low SSB phase noise of typ. -135 dBc (f = 1 GHz, 20 kHz carrier offset, 1 Hz measurement bandwidth), typ. -139 dBc with the enhanced phase noise performance option
• Wideband noise of typ. -153 dBc (CW, f = 1 GHz, >10 MHz carrier offset, 1 Hz measurement bandwidth)
• Excellent ACLR of typically +70 dB for 3GPP FDD
• Very high level repeatability of 0.05 dB
• High output power up to +19 dBm (PEP), overrange + 26 dBm
• High-stability reference oscillator as standard
