About External Devices

Description

Set and return the state of activation of the device. When extDev.IOEnable = True, and this command is set to True, the VNA will attempt communication with the external device. An error is returned if communication cannot be verified.

Note: Send this command AFTER sending other External Device settings to avoid communicating with the device before it has been fully configured.
