Full 2-Port Calibration Using the 2-Port ECal Module
Follow the procedure below to perform a full 2-port calibration using the 2-port ECal
module.
Step 1. Connect the USB port on the ECal module with the USB port on the E5070B/E5071B via a
USB cable. This connection may be done while the E5070B/E5071B’s power is on.
Step 2. Connect port A and port B on the ECal module to the test ports to be calibrated.
NOTE You can connect the ports of the ECal and the test ports of the E5070B/E5071B
arbitrarily.Connected ports can be manually specified although they are automatically
detected before data measurement. For more information,
“Turning off ECal auto-detect
