The latest update to Keysight's IO Libraries Suite, version 2023 Update 1, has been released with several important enhancements and fixes. This update aims to improve performance, resolve known issues, and introduce new features to further streamline the user experience.

New Features

One of the key additions in this update is ARM64EC support for IO Libraries Suite VISA, which expands the suite's compatibility with a wider range of platforms. Another significant addition is KCCS, a WebSocket API gateway that provides seamless access to the IOLS Discovery Service. This feature simplifies integration and improves overall performance.

Performance Enhancements

The update also includes several performance improvements. For instance, the viReadSTB function now takes significantly less time to process for USBTMC instruments, reducing overall processing times. Additionally, VISA-COM APIs for LAN communication have been enhanced for faster and more reliable data transfer.

Bug Fixes and Workarounds

Several known issues have been resolved in this update. One such issue was the missing visa32.dll file in IOLS 2023, which has now been fixed. Another problem that was causing security risks in the electron version of secure-config-client has also been addressed. Furthermore, users who were experiencing conflicts with other applications or services due to KIIS occupying port numbers on Windows 7 SP1 can now breathe a sigh of relief as this issue has been resolved.

Other Fixes and Improvements

The update also includes several additional fixes and improvements. For example, the viUnlock function no longer throws an error (VI_ERROR_SESN_NLOCKED) when the session lock is still active. Additionally, the viLock function now maintains an exclusive session lock on PXI instruments as expected.

Keysight IO Libraries Suite 2023 Update 1 represents a significant step forward in terms of performance, stability, and feature enhancements. By addressing known issues and introducing new features, this update ensures that users can continue to rely on the suite for their IO library needs with confidence. Whether you're working with VISA.NET drivers or leveraging the suite's many other features, this update is a worthwhile upgrade.
