The Keysight 82357B USB/GPIB interface converter is and excellent choice for connecting a USB port to a GPIB device. The interface converter made by RS Components has parallel polling capability with a maximum GPIB transfer rate of 1.15 MB/s. The converter also uses the standard USB and IEEE-488 interfaces. The converter is every easy to use and is a high quality product from RS.
Keysight 82357B USB/GPIB Interface Converter
The Keysight 82357B USB/GPIB Interface converter makes your GPID instruments plug and play when connected to your laptop or computer as there is automatic detection of the 82357B when it is connected to the USB port. The interface supports USB 2.0 high speed with standard USB endpoints.
The interface is also self powered and does not need any external power source. The 82357B USB/GPIB interface also implements the USB 1.1 (12 Mbits/s) and is also fully compatible with USB 2.0 standards. The quality of the product is also very good as the connector is specified to 1,500 insertions which means that it will last you many years of moving the converter around the office or factory.
Keysight 82357B Technical Specifications
You are going to need the Keysight IO Libraries software to make use of the converter. The converter is SICL and VISA 2.2 compatible as well as IEEE-488.1 and IEEE-488.2 compatible. There however unsupported GPIB modes of operation for this converter such as Pass Control as well as Non-System Controller mode. This USB to GPIB interface is typically power by the +5 V, 500 mA (maximum), 200 mA USB port on your computer.
The connectors on the USB to GPIB converter is a standard 24-pin IEEE-488 (GPIB) connector as well as the standard USB A, all of course being self powered. You will note that a single parallel poll can also very easily do a check up on up to eight individual devices and it can do this all at once which also corresponds to the number of data lines on the GPIB interface.
Note however that there is a limitation in this USB to GPIB converter being that there is a maximum of 4 converters which can be connected to the PC and a maximum of 14 instruments all daisy chained via GPIB. Much like the FT231X USB to Serial Adapter there are usable LED lights on this converter. The LED lights on this converter show three LED lights signalling READY, ACCESS, FAIL. Note that the cable on this converter is also 2.5 meters long.
