Erase User Data
All data that you have written to the FieldFox can be erased with the press of a
button. You would do this if your FieldFox is located in a secure environment
and must be routinely erased of sensitive data.
All data is removed from the FieldFox internal “UserData” partition. This
includes all State files and Trace + State files (*.sta), all Data files (*.csv, *.snp),
all Picture files (*.png), all Cal Kit files, and all Cable files.
External media that is inserted (mini-SD card or USB flash drive) is NOT
erased.
The “Lost Clusters" folder and files are NOT erased because they are part of
the file system housekeeping.
How to Erase User Data
1. Press System 7 > Service Diagnostics > Advanced > Erase User Data
2. Then
Confirm Erase
— Then the following occurs:
— All data files and folders are deleted from the “UserData” partition.
— The FieldFox is rebooted, which manages the newly-freed data and
re-writes the factory cal kits and cable files.
IMPORTANT!
The process in this section erases all User Data from the FieldFox. Before
proceeding, Keysight strongly recommends that you back up all of your
User Data to an external storage device. refer to
