Overview
The E5071C 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 VBA macro name (project name)
D:\Agilent EcalCharacterization.vba
Precautions to take in using VBA macros
• Never connect/disconnect the USB cable 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.
• 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.
