產品描述 Microsemi(并購了Symmetricom公司) 5071A銫鐘（原Agilent產品），多年來由于其工作的高可靠性及優異的準確度、穩定性，在時頻領域得到廣泛的認可和使用。5071A操作簡單方便，深受用戶喜愛。閃爍本底指標低達≤1.0E-14。內部銫束管有標準長壽命管和高性能管可選。標準銫束管保修期達5年。 5071A—滿足一級計量校準實驗室要求。 國際上各守時和國家標準實驗室證實了其內部銫標準源相對于UTC的穩定性和準確度。一個標準源的準確性和可靠性決定了守時實驗室的服務質量；標準源的穩定性也極其重要，因穩定性能直接影響實驗室給客戶傳遞時間和校準服務的能力。 5071A提供優異的穩定性，也是列明了超過一天平均時間的穩定性指標的銫頻標。 5071A使用方便，自動啟動和調整，無需手動啟動步驟和復雜的調整操作。邏輯菜單簡化了前面板操作，選擇和狀態報告。遠程控制功能滿足用戶的全面操作和易于管理的需求。 技術指標 • Maintains exceptional accuracy andstability even in unstable environments—unsurpassed stability in the lab or field • Accuracy ±1.0 x 10–12 for standard performance; ±5.0 x 10–13 for high performance • Stability ≤1.2 x 10–11 for standard performance; ≤5.0 x 10–12 for high performance(for 1 second averaging time) • Environmental stability ±1.0 x 10–13 forstandard performance; ±8.0 x 10–14 forhigh performance (frequency changefor any combination of environmentalconditions) • Long-term stability ≤5.0 x 10–14 for standard performance; ≤1.0 x 10–14 for highperformance (for 5-day averaging time) • Proven reliability with an average meantime between failures (MTBF) of greaterthan 160,000 hours • Full traceability to NIST • AC and DC input and internal battery 網絡協議 NTP v1.v2.v3&v4(RFC1119&1305) SNTP(RFC2030) MD5 Authentication（RFC1321）Telne（t RFC854） NTP Unicast,Broadcast,Multicast,Autokey TIME（RFC868) FTP（RFC959）DAYTIME（RFC867) DHCP (RFC2131) RSA 非對稱加密 HTTP/SSL/HTTPS（RFC2616) SNMP v1,v2、 SSH/SCP (Internet Draft) MIB II (RFC1213) WEB 網管監控實時監控統狀態，包括 RAM、CPU 利用率及進程、CPU 平均負載、磁盤分區信息、系統正常工作時間、系統正在運行時間等；顯示系統信息，包括主機名稱、操作系統內核版本、內存、CPU 信息、系統定時任務等；實時監測網口傳輸速率，監測網絡連接，ARP 緩存表，網口帶寬顯示；可直接查詢最近登錄服務器的 IP 地址和登錄日期，及正在登錄賬戶信息。 | 重要特點 ● 全狀態信息顯示 ● 自動記錄主要內部事件 ● 全面的時鐘和頻率控制 ● 自動同步1PPS信號 ● 輸入：1PPS x 2 ● 輸出：5 / 10 MHz x 2(可自設置)；100KHz x 1；1MHz x 1；1PPS x3 重要功能
High-Performance Cesium Beam Tube The 5071A high performance cesium beam tube is optimal for the most demanding operations. The high-performance tube offers a full-environment accuracy specification of ±5.0 x 10–13 —two times better than the specification for the standard tube. Stability is also significantly improved. The high-performance tube reaches a flicker floor of 1.0 x 10–14 or better, and longterm measurements at NIST show that the flicker floor is typically better than 5.0 x 10–15. Integrated Systems and Remote Operation Today, cesium standards are often integrated into telecommunication, satellite communication, or navigation systems asmaster clocks. To accommodate these environments, the 5071A provides complete remote control and monitoring capabilities. Instrument functions and parameters can be interrogatedprogrammatically. Communication is accomplished using the standard commandsfor programmable instruments (SCPI) language and a dedicatedRS-232C port. Also, a rear panel logic output can be programmed to signal when user-defined abnormal conditions exist. For uninterruptible system service, an internal battery provides45 minutes of backup in case of AC power failure. Thus,the 5071A can be managed easily even in the most remotelocations. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
