PNA Calibration File System Description and Issues
In March of 2014, with the introduction of Windows 7, the PNA calibration file format changed to a newer version. The
old version, referred to as "Legacy", is incompatible with the newer version.
If you see the error message "Your calibration file system is full...", it can be caused by one of several conditions:
How the PNA reacts to the memory system format depends upon the firmware revision used. This can be divided into three conditions based on firmware revision:
How and when to convert from one format to the other
If you are using Windows 7 (firmware A.10.00.00 and above), you do not need to worry about anything. The firmware will properly read from either format. If the format is in the older Legacy format, any writing of new calibration files will force the conversion to the newer format. This process is automatic and takes about 1 minute to complete. You will be notified that the conversion is taking place. Windows 7 firmware will not convert the calibration file format until something must be written to memory, such as adding an option or performing an adjustment. PNAs shipped from the factory with Windows 7 will already have the new format in place.
If you decide to insert a hard drive into the PNA that has XP as the operating system, AND the PNA has previously been running Windows 7, AND the file conversion has already taken place, then you will see an error upon boot up. If the XP firmware that was run is A.09.90.05 or above, then you will need to convert the current calibration file system to the Legacy version before continuing. This can be done by running the CalFileSystemConverter program which may be located in the Service directory (C:/Program Files/Agilent/Network Analyzer/Service) but if not, you can download it here. When run, select to convert the calibration file system to "Legacy" format.
Hint: If you are running the PNA with Windows 7 and you know you will later be inserting an XP hard drive, it is recommended that you run the conversion program first, before shutting down the PNA and inserting the XP hard drive. On Windows 7 instruments, the file conversion program is located in: C:/Program Files (x86)/Agilent/Network Analyzer/Service.
If the XP firmware that was run is A.09.90.04 or below, then the cal file system will already be corrupt. You must follow the below process to recover. This process assumes that the hard drive being used is valid for that particular PNA (e.g. it was the one shipped from the factory, and is not a drive from some other PNA that may have been modified to work on the current PNA. This is to insure that all the calibration data is correct for that particular instrument. Follow this procedure:
What to do if the flash memory gets corrupted
If you inserted an XP drive with firmware below 9.90.05, then you will need to follow this process to recover your flash memory. You will need the original Windows 7 SSD that came with your PNA; do not use any other SDD! Follow the steps below.
