Automatically detects the vCal ports connected to the VNA ports and writes the vCal Orientation property. Call this VI before calling RFmxVNA Calibration Initiate VI.

Auto detection of vCal orientation initially occurs at the midpoint of the frequency range specified for the calibration. If the connection is not detected, it retries at the lowest frequnecy in the configured range.

The auto detection may fail if the power level at the vCal module is too low. If it fails, use the vCal Orientation attribute to configure the orientation manually

Note You must select SParams or Wave measurement before calling this VI.
