Firmware update process
The easiest way to update instrument firmware is to connect the instrument to the Internet using Wi-Fi or Ethernet.
The onboard updater will find the most recent update and ask permission to update. Updating an offline instrument is accomplished with the following steps:
- Click on the desired version number below. This is a link to the .lsfw firmware update file
- Copy or save the .lsfw file onto the root directory of a USB flash drive. Make sure it is the only .lsfw file in that location
- Plug the flash drive into the USB-C port on the back of the instrument, if you don't have a newer flash drive with a USB-C connection, use the adapter that was supplied with the instrument
- Restart the instrument to be given the option to perform a firmware update.
- Disconnect the USB flash drive once the update is complete
F71/F41 firmware changelog
- Closed-loop field control commands, settings and UI. Ready for upcoming field control option card hardware
- Probe high frequency compensation - providing more accurate measurement of high-frequency fields
- Buffered data streaming - for continuous acquisition of timestamped readings using SCPI commands
- New drivers: LabVIEW and IVI
- Layout of the main menu drawer improved
- Moved temperature reporting from top taskbar to a new card on the home screen to avoid unresponsiveness of other taskbar elements
- Other general UI improvements
- Improved accuracy of frequency detection in AC and HF mode
- In AC Mode, RMS readings sometimes spiked when DC offsets were high
- Improved error notifications
- General program stability improvements reducing the chance of the instrument having to recover itself
- Changing the Digital I/O functions using SCPI commands were not replicated on the UI

Remaining known bugs
- Headers returned by
FETCh:BUFFer:FORMat? are not formatted consistently
- The first buffered value read back (
FETCh:BUFFer:*) can sometimes be less than the specified averaging window.
- Loss of resolution is possible when measuring very small DC fields in units of tesla. Workaround for now is to measure in gauss. Will be corrected in future version by changing to scientific notation.
