Error Log

See Chapter 8 for instructions on viewing the error log.
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 N9923AN FieldFox RF Vector Network Analyzer User's
Guide (Part Number N9923-90006) 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.
