The Keysight E2094M IO Libraries provide programmatic control of instrumentation from many computer-programming languages. The I/O Libraries conform to the latest VISA (Virtual Instrument Software Architecture) multivendor standard, ensuring a high degree of interoperability among instrumentation vendors providing instruments, controllers, and software. The IO Libraries support Keysight T&M Toolkit, Keysight VEE Pro, NI LabVIEW, NI LabWindows and most windows-compatible programming languages such as C/C++/C#, and Visual Basic (32 bits).


  • Drivers for a wide variety of interface cards
  • C-language and COM interfaces for easy programming in a wide variety of languages
