Firmware Related Information
The error log is cleared each time the analyzer is powered off.
Generally, an entry in the error log is created whenever an error message is displayed.
EXAMPLE: Attempting to set the frequency to a value of "." (a decimal point), will generate an entry in the
error log.

Firmware Upgrades

Firmware upgrades are available on the Internet. Refer to instructions in the "Update FieldFox Firmware"
section of the FieldFox User's Guide for details.
See Chapter 8 for instructions on viewing the current firmware revision.
The following information will be included in the display.
• Firmware Release = FieldFox application firmware revision
• FPGA Rev = code revision for FPGA
• SBM Boot Rev = revision of boot code for System Microcontroller
• SBM Main Rev = revision of main code for System Microcontoller
A firmware upgrade includes three sections:
• the FieldFox application firmware and the Windows CE operation system on the A6 SOM board.
• the firmware in the System Monitor Microcontroller on the A5 system board.
• the FPGA code on the A5 system board.
The System Monitor firmware update and the FPGA code update are executed only if not up-to-date.
It is important to maintain power to the analyzer during the update process.
After unplugging the USB flash memory stick during the firmware upgrade process, wait for the analyzer to
activate the CAT mode before operating the analyzer.
