選用二手測(cè)量?jī)x器的優(yōu)勢(shì)是：
1、與新購(gòu)儀器幾個(gè)月的供貨期相比，購(gòu)買(mǎi)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(wú)疑是最為明顯的。
2、二手儀器的價(jià)格便宜，基本為新購(gòu)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(xiāo)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(guó)家級(jí)計(jì)量測(cè)試單位進(jìn)行校準(zhǔn)。
The MS4630B is suitable for electronics production lines demanding fast and accurate device measurements. It is particularly well suited to accurate, high-speed evaluation of IF filter resonance and group delay characteristics, as well as evaluating the impedance characteristics of resonators in AV equipment and PCs.

A fast sweep speed of 150 µs/point is achieved using a high-speed synthesizer and digital signal processing (DSP) technologies. The post-processing data analysis functions have been strengthened with improved data processing macros that greatly increase the total production throughput.

In comparison to the earlier MS3401A/B and MS3606B network analyzers, the sweep speed is three times faster and the group delay measurement accuracy and stability have been improved by more than 10 times. In addition, the dynamic range has been improved to 120 dB (RBW: 1 kHz) while the weight of the analyzer has been dramatically reduced. Compatibility has been maintained between PTA and GPIB software commands, maintaining any current investment in PTA software.

• Frequency Range: 10 Hz to 300 MHz
• High speed evaluation of devices such as IF filters and resonators
• High speed production/inspection capacity
