Firmware-Update - Gigahertz Solutions NFA 1000 Operating Manual

8 Firmware Update
The file: "firmware.nfa" is the meter's operating system stored in its internal
16
memory . As known from computer programmes, this software is subject to contin-
uous improvements and upgrade, and can be updated as follows:
Procedure for the Update:
Copy the new "firmware.nfa" file onto your SD memory card.
If need be, overwrite any old
versions as only one "firmware.nfa" file should be on the card. It should not be renamed.
Lock your SD memory card
by switching the small switch on left side of the card to "lock".
Insert SD card into your powered-off NFA.
Turn on your NFA. The display will show "CodE", the frequency LEDs will gradually
change from green to red during the update process. Then all LEDs will turn off ex-
cept for the status LED. As soon as the status LED is green, the update process is
completed.
Do not switch the meter off during the update process!
Please remember to unlock the SD-card before applying the new firmware!
Which is the active firmware on your NFA?
Press the "Mode"-button while switching on the meter, and you will be shown the
currently active firmware version for a short period of time.
The NFA always has two firmware versions in its memory. In order to switch from
one version to the other, press the "Mode" and the "Rec."-button simultaneously.

Please differentiate: With „NFAsoft" one can configure the firmware, with these user settings being stored in the
file „CONFIG.NFA". This has nothing to do with the firmware update described above.
