Follow these steps to measure characteristics while an adapter is
connected to the ECal module and then to store them to the ECal module's
built-in flash memory as user characteristics.
With the 2-port E5071C, you cannot measure the user
•
characteristics of a 4-port ECal module and store them into the
memory by using this VBA macro.
1. Connecting ECal Module
Connect the USB cable between the USB port of the ECal module and that
of the E5071C. You can make this connection while the E5071C's power is
ON.
2. Setting Stimulus Condition
Set the stimulus condition of the channel for which you want to measure
the user characteristics. For optimal accuracy, set the IF bandwidth to 1
kHz or less.
3. Executing Calibration
For the channel for which you have set the stimulus condition, execute full
2/4-port calibration with a mechanical calibration kit when characterizing
2/4-port ECal. Define the calibration surface as the connector surface
connected to each port of the ECal module in the state used to measure
characteristics.
