Keysight 82357B USB/GPIB Interface Product Introduction
Overview
Keysight 82357B(formerly Agilent 82357B)is a high-performance USB/GPIB conversion interface for connecting GPIB instruments directly to the USB port of a laptop or desktop computer.Its design is based on plug-and-play,high-speed transmission and compatibility.It does not require additional switches,PC cards or external power supplies,simplifying the construction and maintenance of the test system.
Main Features
Plug-and-Play and Compatibility
-Supports USB 2.0 standard(compatible with USB 1.1),and realizes automatic detection and configuration through a standard USB interface,without the need to manually install drivers or configure software.
-Compatible with IEEE-488 interface,supports connection of up to 14 GPIB instruments,suitable for complex test environments.
High-speed transmission and stability
-Provides a GPIB transmission rate of more than 1.15MB/s,supports small program block transmission,and significantly improves data acquisition efficiency.
-Use a shielded USB cable(2.5 meters long)and the connector can be plugged and unplugged 1500 times,ensuring long-term reliability and durability.
Intelligent design
-Parallel polling function:A single poll can check the response of 8 devices at the same time,optimizing the efficiency of multi-instrument collaboration.
-LED indicator:The three status lights READY,ACCESS,and FAIL monitor the connection status of the interface and instrument in real time.
Expansion and flexibility
-Self-powered design,directly powered by the USB bus(+5V,maximum 500mA),without the need for an additional power adapter.
-Support hot plugging,and can dynamically connect or disconnect instruments without shutting down the computer.
