NI GPIB-140 光纤 GPIB 延长器. GPIB-140A 186135G-01

NI GPIB-140 光纤 GPIB 延长器. GPIB-140A 186135G-01

特点:

高速串行光纤传输

传输速率超过1.1兆字节/秒(IEEE 488.1)或2.8兆字节/秒(HS488)

将GPIB设备的数量扩展到26个

缓冲或无缓冲传输

National Instruments GPI b-140/GPI b-140 a光纤GPIB扩展器消除了IEEE 488标准对电缆长度和设备负载的限制，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20米，设备的最大数量是15个。一对NI GPIB-140A/2总线扩展器可以将电缆长度延长至2千米，而不会影响GPIB的完整性，也不需要任何应用修改。GPIB-140A可以使用长达1千米的光缆。

这些GPIB扩展器使用缓冲传输技术，以业界最快的速度传输数据，同时将布线成本保持在最低水平。每个扩展器都有一个错误检查方案，以确保无错误链接。使用HS488协议，GPIB-140A扩展器的最大数据传输速率超过2.8兆字节/秒。

Features:

High-speed serial fiber transmission

Transfer rates exceeding 1.1 megabytes per second (IEEE 488.1) or 2.8 megabytes per second (HS488)

Expand the number of GPIB devices to 26

Buffered or unbuffered transmission

The National Instruments GPI b-140/GPI b-140 a Fiber optic GPIB extender eliminates the limitations of the IEEE 488 standard on cable length and device load while requiring virtually no desktop space. The IEEE 488 standard specifies that the total cable length of a GPIB system cannot exceed 20 meters, and the maximum number of devices is 15. A pair of NI GPIB-140A/2 bus extenders can extend the cable length up to 2 km without compromising the integrity of GPIB and without requiring any application modifications. The GPIB-140A can use up to 1 km of cable.

These GPIB extenders use buffered transfer technology to transfer data at the industry's fastest speeds while keeping cabling costs to a minimum. Each extender has an error checking scheme to ensure error-free links. Using the HS488 protocol, the GPIB-140A extender has a maximum data transfer rate of more than 2.8 megabytes per second.
