User-characterized ECal

The E5070B/E5071B allows you to execute ECal calibration with user-defined

characteristics instead of the ECal characteristics defined as the factory default. This

feature is called User-characterized ECal, and it is used to execute ECal calibration when

an adapter is connected to the ECal module.

Before executing the User-characterized ECal, you have to measure data, such as

characteristics when the adapter is connected to the ECal module, and store them to the

built-in flash memory of the ECal module as the user characteristics.

Use the following VBA macro to acquire user characteristics and store them to the ECal

module's built-in memory.

Storage folder

This function is available with firmware version 3.50 or higher.

Never delete this VBA macro, since even system recovery cannot restore it.

o Never connect/disconnect the USB cable.

Never connect/disconnect the USB cable between the ECal module and the

E5070B/E5071B while executing the VBA macro.

In particular, the above precaution must always be observed while the VBA macro is

storing data to the ECal module's built-in flash memory; disconnecting the USB cable

at this time may damage the ECal module.

o Back up the flash memory contents.

The VBA macro provides a feature to back up the contents of the ECal module's

built-in flash memory. Before storing user characteristics to the ECal module, be sure

to use this feature to back up the flash memory's current contents.
