Re: E4407B strange peak shapes at low RBW

Usually the security sanitization requirement ONLY applies to user data which means every piece of data that was stored by the user it does NOT apply to factory data !
What this means in real life is that all memory that is accessible by the user to store memory has to be either cleared or sanitized , this therefore applies to battery backed RAM , flash as well as HDD.
The calibration data for each module however is stored in EEPROM on each module making it possible to change a assembly without having to completely recalibrate the unit , since this is not considered user data no clearing or sanitizing
is required

Going from memory is not always the best thing,? it¡¯s the NISPOM security sanitization of the instrument.
Its in this document E4401-90513 - Security Features
I¡¯ll see if it attaches to my reply

It does require you to reload all firmware so you have to have the full set of floppies after you do it.

I assume you¡¯ve tried a align all already and it didn¡¯t help.
I can not guarantee this is fix your issue,? only that it fixed mine.

Hi Sandra,
What is a NSCOM reset?
Do you mean factory reset / preset on the machine itself or some command?
