Creating and Applying User Flatness Correction
Save the User Flatness Correction Data to the Memory Catalog
This process allows you to save the user flatness correction data as in the signal generator’s memory catalog.
With several user flatness correction files saved to the memory catalog, any file can be recalled, loaded into
the correction array, and applied to the RF output to satisfy specific RF output flatness requirements.
