Post-Repair Procedures
FPGA Synchronization
There is FPGA (Field-Programmable Gate Array) program code on many
different assemblies inside of the instrument, and all of these must be of a
compatible version with the instrument software revision. In order to ensure
that this requirement is met when either an assembly is replaced that contains
FPGA code on it, or if the A5 Disk Drive is replaced with a drive that has a
different version of software than the previous drive, you will need to take
certain steps to ensure that the instrument operates properly.
Updating the Instrument FPGA Code
All instruments have a utility included in them that will update the FPGA code
on all of the different assemblies in the instrument that have it. When this
utility is run it will detect the assemblies that need to be updated and will
update them to the correct revision.
1. Close the instrument application software by pressing File, Exit, Enter
using the front panel keys.
2. Connect a USB mouse to one of the instrument front panel USB ports.
3. Using the mouse, click Start, Log Off, Log Off.
4. Re-login as “administrator”. The default password is “Keysight4u!”. Click
OK.
5. Using the mouse double-click on the Windows Explorer link on the
desktop and navigate to the following folder:
C:\Program Files\Agilent\SignalAnalysis\Physics
6. In this folder find and execute the file named:
FPGA_Prog.bat
7. The FPGA Programming Utility will start and a window as shown in Figure
17-11 will appear.
Even if an instrument appears to work properly when an assembly with
FPGA code is replaced, that does not mean that the FPGA code is
completely compatible with the software version installed in the
instrument. There could be incompatibilities that will only be seen under
certain measurement conditions.
Once you start the FPGA programming process you MUST NOT interrupt
the process for any reason. This would include turning the instrument off
or unplugging the power cord to the instrument. Doing so will result in an
inoperative instrument, requiring the affected assembly to be replaced.
