Welcome to Keysight IO Monitor

IO Monitor is a message-tracking utility for all messages originating from the following Keysight IO Libraries:

• VISA
• SICL
• VISA COM
• IVI-COM instrument drivers released after September 18, 2010

These messages are a helpful resource when analyzing communication between test & measurement instruments and the controller PC.
