About Command Expert

Keysight's Command Expert software combines instrument commands, documentation, syntax checking, command execution, and code generation all in one simple interface. Command Expert works with instruments that use Standard Commands for Programmable Instrumentation (SCPI), IVI-C,  or IVI-COM drivers.

Command Expert generates a SCPI.NET driver for each SCPI command set you install, for use in Visual Studio applications.

Command Expert Add-ons let you use Command Expert for easy instrument control in Excel, LabVIEW, MATLAB, Python, SystemVue, VEE, and Visual Studio.

New Features and Changes In Command Expert 1.5


  • In 2014 Keysight's Electronic Measurement Group became Keysight Technologies. In Command Expert 1.5, installation paths, namespaces, etc. have been updated to reflect our new name. Your sequences and calling programs will continue to work as before.
  • MATLAB agXxx functions (agSequenceInfo, agRunSequence, etc.) have been superseded by equivalent ktXxx functions(ktSequenceInfo, ktRunSequence, etc.). The agXxx functions are still available for backwards compatibility.

New Operating Systems / New Development Environments

  • Microsoft Windows 10
  • Microsoft Office 2016
  • Python 3.2, 3.3, and 3.4
  • 64-bit Python for all supported Python versions
  • MATLAB R2015a and R2015b
  • LabVIEW 2015
  • See the documentation for a complete list of supported environments

Other changes

  • You can now upgrade your Python installation without reinstalling Command Expert.
  • Add Command now adds the new command immediately below the selected command. A new setting (in File > Options) allows you to revert to the previous behavior of adding new commands at the end of the sequence.

Defect fixes

  • A memory leak in the LabVIEW addon was fixed
  • A defect where Excel would no longer ask to save the Workbook before closing was fixed
  • Various other defects fixed

Supported Instruments

To see which SCPI instruments are supported, use the Manage Command Sets dialog box in the Command Expert application, or visit Instruments Supported by Command Expert

Command Expert also lets you control instruments using IVI-COM and IVI-C drivers.
