Can't recall saved calibrations from SD card. #calibration #firmware #nanovna-h4


 

Hi there, I’m running Hugen’s 1.2.14 firmware, which I like because it lets you save more calibrations. It will also do more data points across the sweep.
But I lost some of the defaults along the way, so I have some questions.
What Expert settings do people use for stuff like Electrical Delay and Threshold?
And what does REMEMBER STATE do?
Lastly, I can save my calibrations to the SD card, but can’t find a way to recall them from it!
Any guidance gratefully accepted. Thanks


 

Remember state - allow save some device settings after power off like:
Start/stop frequency
Bandwidth
Backlight
Options

Threshold - this option set frequency threshold after this device use harmonic mode for measure
Old calibration not possible load on new firmware, need recalibrate and save new


 

Thanks for the reply and information.

I did recalibrate and saved them to SD. But the RECALL FROM SD menu item isn't there in 1.2.14. I rolled back to 1.2.0 for now.

Regards
