Re: Latest edy555 firmware release with dfu file
Hello Ralph, You could also omit the "-d 0483:df11" parameter from the dfu-util command line. Ralph Thank you for the hint, but see the man page: -d, --device [Run-Time VENDOR]:[Run-Time

Hello Norbert, Thank you very much! :-) The "span" value is the -3 dB bandwidth - assuming the -3 dB points get placed correctly. The setup currently analyses as follows: 1) From the marker 1

Re: Offtopic: nanoSA
If I can say a little something about this Idea. A tracking generator would not cost a lot more in ressources and would be a nice addon in a NanoSa. And the possibility to add an amplifier to the TG

Re: Offtopic: nanoSA
Yes, it would be very useful. But could one go further and combine the SA & VNA into one unit? For what it is worth, Keysight sell a range of portable FieldFox instruments. They are either *

Been looking at this lab card, and I wonder what is it useful for? I must not get it.. Is it a way to test our NanoVNA?

While described as 101 fixed steps, fewer are evidently used by nanoVNA firmware for small spans. Given Si5351 setting granularity for artifact-free switching, what are rule-of-thumb minimum

Re: NanoVNA-Saver 0.1.1
Hi Rune, first impression is outstanding! If you take a look at the BP-Filter I can't find the value of the width for the bandpass in respect to the -3dB points. Same for the -6dB BW. LP&HP analysis

Re: Offtopic: nanoSA
If calibrated for amplitude at spot frequencies using nanoVNA, then could some SDR (e.g. SDRplay has Android API) be useful for spectrum analyses?

What amplitude (dB) and phase (degrees) resolution are credible for nanoVNA? I read e.g. 0.1dB and 1 degree for other VNAs for amateurs..
