About External Devices

Description

Sets and returns whether an external device is enabled for IO communication with the VNA.

When disabled (False), the VNA will NOT attempt to connect to the external device regardless of the instrument state (Active).property.  Therefore, no errors will be produced if the device is not connected.

This command is useful for debugging and testing states when the external device is not connected. This command is unnecessary in ordinary operation (when the device is connected).
