Some Keysight IO Libraries Connection Expert settings and Keysight Instrument Discovery Service policies affect the operation of Open. Refer to the IO Libraries Suite Help for more details.

For instruments that are auto-discovered by the Discovery Service, Open verifies that the instrument is present.

For instruments that are manually-added, Open does not verify the presence of the instrument. If the device is not present or not turned on, you will not discover this until you attempt to communicate with the instrument.
