【功能描述】
1 km，GPIB总线扩展器—GPIB-140A可将GPIB系统的线缆延长一千米，而不会影响GPIB的完整性，也无需修改软件。该配件使用缓冲传输技术，数据传输速率高达1.1 Mb/s (IEEE 488.1)或2.8 Mb/s (HS488)。GPIB-140A还可以将GPIB系统中GPIB设备的最大数量从15个增加到26个。
特征：
高速串行光纤传输
传输速率超过 1.1 MB/s （IEEE 488.1） 或 2.8 MB/s （HS488）
将GPIB器件数量扩大到26个
缓冲或无缓冲传输
National Instruments GPIB-140 / GPIB-140A 光纤 GPIB 延长器消除了对 IEEE 488 标准规定的电缆长度和设备负载 同时几乎不需要桌面空间。IEEE 488 标准 规定GPIB系统的电缆总长度不能超过GPIB 20 m，最大设备数为 15。一对 NI GPIB-140A/ 2 总 线 延长 器 可 将 电缆 长度 延长 至 2 km 在不损害GPIB完整性或要求任何 应用程序修改。GPIB-140A可以使用光纤电缆 长度可达 1 公里。 这些GPIB扩展器采用缓冲传输技术，以业界最快的速率传输数据，同时将布线成本保持在最低水平。

【英文介绍】
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.
