Logic analyzer 16861A: installing the latest instrument solftware version. 06.50.0001, I get the Keysight Service Notification Error: "Failed to get physical slot number from blade". As a consequence the instrument is only a PC and not an instrument. Prior to the installation I the 16861A got a Windows 10 Enterprise upgrade from Windows 7.
You should get in touch with your local Keysight Technical Call Center, if you haven't already. The Keysight Technical Forums are for peer-to-peer communication, and are not a good way to contact Keysight technical personnel. The Forums are not monitored regularly.
