Keysight IO Libraries Suite 2026 Update 1

What's New?

• Connection Expert
  • Flexible Instrument Views — Toggle between a consolidated, flat list of all instruments and an interface-organized hierarchy with instruments nested underneath.
  • Multi-select support — Select multiple instruments and manage them in a single workflow.
• Interactive IO
  • Faster Command Execution — Perform common operations more quickly with Send Command, Read Response, and Send & Read buttons, while Auto Mode intelligently selects the appropriate action when you press Enter.
• IO Monitor
  • Efficient Data Search — Quickly find captured data by searching across all column values in the Overview pane.
  • Streamlined Error Analysis — Identify and isolate error responses more easily with dedicated error indicators and filtering options.
• Telemetry
  • Optional Usage Analytics — IOLS provides an option to share anonymous usage information during installation to help improve the product. No personal information, instrument data, or measurement results are collected.

Defect fixe(s)

• Simplified the InstrumentInfo API error message when a queried instrument is not registered in Connection Expert — the verbose path details have been removed.

Enhancement(s)

• Connection Expert
  • Persistent user preferences — Your column filters, preferred view, image display, and theme are remembered every time you open Connection Expert.
  • Optimized toolbar — A cleaner, better-organized toolbar puts the actions you need most within easy reach.
  • Adaptable side panels — Drag to resize side panels so instrument and interface details fit the way you work.
• Interactive IO
  • Simplified Instrument Connections — Connect to instruments more easily using a redesigned, partially collapsible panel with Browse Available Instruments and Resource String connection methods and a dedicated Connect button.
  • Streamlined Session History Management — Access Search and Clear History directly within the Instrument Session History panel for faster navigation and cleanup.
• IO Monitor
  • Consistent Theme Experience — Your preferred dark or light theme is automatically remembered, so IO Monitor opens the way you left it.
  • Personalized Table Layouts — Resize, show, or hide columns to tailor the message table to your workflow, with your column preferences preserved across sessions.
• Security Enhancements
  • Added encrypted databases to protect sensitive data.
  • Implemented a generic rate-limiting mechanism across all web-based components.
