Does the touchstone file generated by the ENA / ENA-L include the electrical delay?
(SUPPORTED MODELS IN BOLD: E5071C E5070B/71B E5070A/71A E5061A/62A E5061B E5072A)
The touchstone file does not include electrical delay. Please use port extension.
Electrical delay adds/removes transmission line on the display (thus, Electrical Delay is under the "SCALE" menu)
Port Extension extends the calibration plane by specifying electrical delay (thus, Port Extension is under the "CAL" menu)
Details on port extension and electrical delay are available in "Optimizing Measurements-Improving the Accuracy of Phase Measurements" Section of the User's Guide.
