公司簡(jiǎn)介：
Berkeley Nucleonics Corporation（BNC）是用于測(cè)試、測(cè)量和核研究的精密電子儀器的制造商。我們的公司總部位于加利福尼亞州的圣拉斐爾，在美國各地設(shè)有額外的生產(chǎn)設(shè)施和銷售辦事處。
Berkeley Nucleonics Corporation（BNC）擁有一個(gè)制造商代表的國際網(wǎng)絡(luò)，包括Optilas、堪培拉Packard、ORTEC、Concertant和Seiko，以滿足全球精密儀器的需求。
BNC成立于1963年，最初開發(fā)了定制脈沖發(fā)生器。我們以滿足對(duì)高精度和穩(wěn)定性的最嚴(yán)格要求，以及生產(chǎn)具有的可靠性和性能的儀器而***。作為定制脈沖、信號(hào)、光和函數(shù)生成器的開發(fā)人員，我們繼續(xù)保持地位。我們的設(shè)計(jì)融合了軟件和硬件工程、表面貼裝生產(chǎn)和自動(dòng)化測(cè)試程序方面的創(chuàng)新。我們的62***型函數(shù)發(fā)生器已獲得多個(gè)電子行業(yè)獎(jiǎng)項(xiàng)，包括1999年Cahners electronics Group的“年度T&M產(chǎn)品”獎(jiǎng)。
BNC的創(chuàng)新工程已經(jīng)產(chǎn)生了一系列備受推崇的數(shù)字延遲發(fā)生器（DDG）。迄今為止，我們已經(jīng)引入了15種不同的DDG，延遲分辨率低至250飛秒。每年的媒體調(diào)查都將我們列為DDG生產(chǎn)商的層。
產(chǎn)品簡(jiǎn)介：
Berkeley Nucleonics公司的845型RF微波信號(hào)發(fā)生器是一種低噪聲、快速切換的微波信號(hào)發(fā)生器，覆蓋甚低頻至K波段，100 kHz至26.5 GHz（可選擇將頻率延長(zhǎng)至9 kHz）。845型微波射頻信號(hào)發(fā)生器提供寬而輸出功率范圍和高雜散抑制。采用分?jǐn)?shù)N分頻器的***頻率合成可實(shí)現(xiàn)低SSB相位噪聲和亞赫茲頻率分辨率。
BNC 845型可提供12、20和26.5 GHz頻率，帶有觸摸屏顯示器。此外，845型可根據(jù)每個(gè)用戶的具體需求進(jìn)行定制和配置。有許多選項(xiàng)可用于確定配置。請(qǐng)參閱下面的選項(xiàng)列表或聯(lián)系BNC以獲得支持。
