Description
The National Instruments GPIB Expander/Isolator, model GPIB-120A, is a sophisticated device designed to enhance the capabilities of GPIB systems. It falls under the category of GPIB and carries a range of part numbers including 776564-01 to 776564-06. This device is specifically engineered to comply with the IEEE 488.1 interface system standard, ensuring broad compatibility and high performance.
One of the key features of the GPIB-120A is its ability to expand the device limit from 15 to 28 devices, significantly increasing the scalability of GPIB systems. Furthermore, it doubles the cable length limit to 40 meters, offering greater flexibility in the setup and layout of instruments and equipment. The GPIB-120A operates with a dual bus configuration, known as Bus A and Bus B, each with identical circuitry and complete isolation. This design ensures robust performance and reliability, even in complex systems.
The GPIB-120A boasts impressive electrical characteristics, with operating and breakdown isolation rated at 60 V and 1600 V, respectively. This high level of isolation provides added safety and stability, protecting against electrical interference and potential damage. The device supports various connector types, including Amphenol or Cinch series 57 Microribbon or Amp Champ type, offering versatility in connecting different instruments.
Another notable feature of the GPIB-120A is its transparent software compatibility, which means there is no need to rewrite the user’s application software. This greatly simplifies integration and reduces setup time. The front panel of the device is equipped with seven LEDs that indicate the Active Controller and System Controller states, providing immediate visual feedback on the system’s status.
Finally, the GPIB-120A supports a comprehensive range of signal lines, including five interface management lines, three handshake lines, and eight data lines. This enables the device to handle a wide variety of data transfer requirements, ensuring efficient communication between GPIB instruments. With its advanced features and specifications, the GPIB-120A is an essential tool for expanding and isolating GPIB
