Description
The GPIB-120A is a specialized GPIB Expander/Isolator designed to enhance GPIB networks. It carries the Part Number 18155 and falls under the GPIB category. This device is specifically engineered to adhere to the IEEE 488.1 standard, ensuring compatibility and reliable performance in demanding applications.
One of the key features of the GPIB-120A is its ability to expand the device limit from 15 to 28 GPIB devices, significantly increasing the capacity of GPIB networks. Furthermore, it offers a solution for extending cable length beyond the standard 20 meters limit, effectively doubling the reach of GPIB connections. This feature is particularly beneficial in large-scale setups where devices are spread out over greater distances.
The GPIB-120A is designed with two bus configurations, Bus A and Bus B, each equipped with identical circuitry that provides complete isolation between the buses. This isolation is critical for ensuring uninterrupted and reliable communication among connected devices. The device boasts operating and breakdown isolations of 60 V and 1600 V, respectively, offering added protection against voltage spikes and electrical noise.
Compatibility with various connector types is also a notable feature of the GPIB-120A. It supports Amphenol or Cinch series 57 Microribbon and Amp Champ type connectors, providing flexibility in connecting different GPIB devices. Additionally, the device is equipped with seven front panel LEDs, including indicators for active controller and system controller statuses, offering at-a-glance monitoring of the system’s operation.
Moreover, the GPIB-120A supports transparent software compatibility, ensuring seamless integration and operation within existing GPIB networks without the need for additional drivers or software modifications. It also manages 16 signal lines, comprising five interface management lines, three handshake lines, and eight data lines, facilitating efficient data transfer and communication between connected devices.
In conclusion, the GPIB-120A, with its comprehensive
