Modified from GPIB to USB device designed by Japanese fenrir, and the main control was changed to C8051f383-GQ in LQFP-32 package. According to the data manual of C8051f383, the main control has been able to meet the driving capability of about 10 instruments, eliminating the need for additional driver chips and adding The ESD protection of the interface is ensured to ensure stable operation. Designed a simpler and more compact PCB that can be installed in a standard GPIB interface shell to ensure that the interface can be reliably connected.

Provide two types of shells for direct wire bonding to the PCB or use USB-B. Direct wire bonding can retain two interface screws, which can be more securely connected to the instrument. USB-B can only be retained because the USB port blocks a screw port. An interface screw can also ensure the firm connection of the interface after testing. It can be easily used from USB to GPIB at the standard GPIB interface.
