中賽儀器庫(kù)存大量各種高頻儀器現(xiàn)貨特價(jià)出售中--本公司長(zhǎng)期現(xiàn)金大量高價(jià)回收各種高頻儀器;如-網(wǎng)絡(luò)分析儀-視/ 音頻分析儀-信號(hào)發(fā)生器-頻譜分析儀-手機(jī)綜合測(cè)試儀 阻抗分析儀 LCR電橋 示波器 高壓測(cè)試儀靜電放電發(fā)生器等等…..儀器聯(lián)糸人；張彬 */*電話；*傳真； *

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 MG3690B series of broadband signal generators covers both RF and microwave frequencies from 0.1 Hz to 70 GHz. For mmW frequencies, the MG3690B’s coverage can be extended up to 325 GHz or beyond, with external multipliers. Thus, the MG3690B series is an ideal signal source for both RF and microwave requirements, fully configurable from simple to high performance applications.

The MG3690B microwave signal generator series also offers the highest output power, best-in-class spectral purity, and fastest switching speed. For example, the MG3692B can provide guaranteed +23 dBm at 20 GHz with -94 dBc/Hz phase noise at 1 kHz offset while typically switching at 5 ms per point! This level of performance eliminates the need for external amplification, enables the verification the toughest spectral purity requirements, and greatly reduces test times. If 5 ms per point is not fast enough then switch to the optional analog ramp sweep for even faster measurements.

MG3691B	2 to 10 GHz
MG3692B	2 to 20 GHz
MG3693B	2 to 30 GHz
MG3694B	2 to 40 GHz
MG3695B	2 to 50 GHz
MG3696B	2 to 67 GHz
