Instrument Firmware and Operating System
Instrument Firmware
If there is an assembly in an instrument with a part number listed in Table 19-1
a firmware version older than that listed in the Minimum Firmware column
should not be used, as it will either generate errors or not perform as intended.
FPGA Code Versus Firmware
Different firmware versions have different FPGA version dependencies, and the
FPGA code in the instrument can only be updated with a firmware installation.
Because of this, whenever either the A5 CPU assembly or an assembly with
FPGA code on it is replaced the instrument firmware should be reloaded after
the assembly replacement to make sure that all the FPGA versions are correct
for the firmware version being used. This does not have to be the latest
firmware version, as long as the hardware versus firmware dependencies are
being met.
Instrument Firmware Updates
The firmware and all its components are all loaded at the same time. This
includes the FPGA code that resides on different assemblies in the instrument.
The latest version of the instrument firmware can be downloaded from:
http://www.keysight.com/find/ss_firmware
Instructions on how to install the firmware can also be found at this location.
If the firmware appears to have somehow become corrupted and cannot be
reloaded by the normal update process, try using the Recovery Firmware
process. For detailed information on how to do this see“Boot Service Menu”
section in Chapter 5, “Service and Utility Menus”
a. These are the part number found on the Utility, Instrument Info, Installed Board Info
screen.
