>>>>>型號(hào):GPIB-140A 光纖GPIB延長器 總線擴(kuò)展器
【功能描述】
1 km，GPIB總線擴(kuò)展器—GPIB-140A可將GPIB系統(tǒng)的線纜延長一千米，而不會(huì)影響GPIB的完整性，也無需修改軟件。該配件使用緩沖傳輸技術(shù)，數(shù)據(jù)傳輸速率高達(dá)1.1 Mb/s (IEEE 488.1)或2.8 Mb/s (HS488)。GPIB-140A還可以將GPIB系統(tǒng)中GPIB設(shè)備的最大數(shù)量從15個(gè)增加到26個(gè)。
特征：
高速串行光纖傳輸
傳輸速率超過 1.1 MB/s （IEEE 488.1） 或 2.8 MB/s （HS488）
將GPIB器件數(shù)量擴(kuò)大到26個(gè)
緩沖或無緩沖傳輸
National Instruments GPIB-140 / GPIB-140A 光纖 GPIB 延長器消除了對 IEEE 488 標(biāo)準(zhǔn)規(guī)定的電纜長度和設(shè)備負(fù)載 同時(shí)幾乎不需要桌面空間。IEEE 488 標(biāo)準(zhǔn) 規(guī)定GPIB系統(tǒng)的電纜總長度不能超過GPIB 20 m，最大設(shè)備數(shù)為 15。一對 NI GPIB-140A/ 2 總 線 延長 器 可 將 電纜 長度 延長 至 2 km 在不損害GPIB完整性或要求任何 應(yīng)用程序修改。GPIB-140A可以使用光纖電纜 長度可達(dá) 1 公里。 這些GPIB擴(kuò)展器采用緩沖傳輸技術(shù)，以業(yè)界最快的速率傳輸數(shù)據(jù)，同時(shí)將布線成本保持在最低水平。

【英文介紹】
1 km, GPIB Bus extender - The GPIB-140A extends the cable of the GPIB system by one kilometer without compromising the integrity of the GPIB and without software modification. The accessory uses buffered transmission technology with data transfer rates up to 1.1 Mb/s (IEEE 488.1) or 2.8 Mb/s (HS488). The GPIB-140A can also increase the maximum number of GPIB devices in a GPIB system from 15 to 26.
Features:
High-speed serial fiber transmission
Transfer rate exceeding 1.1 MB/s (IEEE 488.1) or 2.8 MB/s (HS488)
Expand the number of GPIB devices to 26
Buffered or unbuffered transmission
The National Instruments GPIB-140 / GPIB-140A Fiber optic GPIB extender eliminates the cable length and device load required by the IEEE 488 standard while requiring little desktop space. The IEEE 488 standard specifies that the total cable length of a GPIB system cannot exceed 20 m GPIB, and the maximum number of devices is 15. A pair of NI GPIB-140A/ 2 bus extenders can extend cable lengths up to 2 km without compromising GPIB integrity or requiring any application modifications. The GPIB-140A can use fiber optic cables up to 1 km in length. These GPIB extenders use buffered transfer technology to transfer data at the industry's fastest rates while keeping cabling costs to a minimum.
