Modern Connectivity for Classic Instrumentation
Modern USBTMC Connectivity for Legacy GPIB Instruments - Reliable, Compact, Compatible, Open-Source and Future‑Proof.
Compact design with USB-C connector and GPIB interface
Ultra-slim 1.5cm profile for space-efficient installation
Standard GPIB connector for universal compatibility
Why USBGpib V2 is the superior choice for modernizing your GPIB instruments
Minimal depth of just 1.5 cm ensures that instruments can be positioned closer to walls or rack panels, maximizing workspace efficiency.
Unlike traditional "garden hose" GPIB cables, the UsbGpib V2 uses standard thin USB cables, dramatically reducing clutter and improving portability on the bench.
Each adapter includes a unique identifier, allowing multiple UsbGpib V2 units to be connected and operated reliably on the same PC.
Supported across all major operating systems - Windows, macOS, FreeBSD, and Linux - ensuring broad compatibility without custom drivers.
Integrates smoothly with LabVIEW, PyVISA, and MATLAB, making it a drop-in solution for both established and modern measurement software stacks.
With full USBTMC class compliance, the adapter transforms any GPIB instrument to operate seamlessly like modern USB-based measurement equipment.
Professional-grade performance designed for laboratories, automated test environments, and personal users

Real feedback from engineers and researchers using USBGpib V2 in their labs
"I just plugged it in and it worked immediately. I didn't have to fight with any drivers or complex software setups like I've had to do with other brands."
"It's a true 'plug and play' experience. I love that it doesn't clutter my COM ports - it only shows up when I actually have an instrument powered on and connected."
"The 'AutoID' feature is brilliant. It identifies my instruments by name automatically, which makes organizing my lab bench so much easier."
"I've used this on everything from my old HP and Tektronix gear to my modern Rohde & Schwarz and Keithley units. It handles them all without a hitch."
"It integrates perfectly with my existing workflow. I'm running it with LabVIEW, MATLAB, and PyVISA, and it hasn't missed a beat."
"The speed is impressive when I pull screenshots from my scope, which is way faster than the serial-to-GPIB adapters I used to use."
"It just works flawlessly under Linux. I plugged it into my Ubuntu machine, and it was recognized immediately. Honestly, it's refreshing to have a device that doesn't require a weekend of troubleshooting just to see an instrument."
"I finally threw away my cheap clones. This adapter fixed all the stability issues I was having and is much more reliable for long-term data logging."
"It feels like a professional, high-quality tool. I really appreciate that it fits into the GPIB socket without blocking the ports next to it."
"It's refreshing to use a tool where I can actually see how it works. Knowing it's open-source gives me a lot of confidence that I'll be able to use it for years to come."
"I've replaced my expensive 'big brand' controllers with these. For the price and the open-source transparency, there's really no reason to buy the proprietary stuff anymore."
"The SRQ (Service Request) support actually works! Most DIY adapters skip that, but having proper interrupt-based signaling on Linux makes my automation scripts way more robust."
"The support is fantastic. When I had a specific timing issue with an older instrument, I got a helpful, technical response right away."
"I really appreciate the responsiveness. It's clear that the person behind this understands both the hardware and the needs of a working lab."
