So just to clarify - are the new H4 units from R&L Electronics presently shipping with all required hardware to use a (user supplied) microSD card? 1) Or must the above discussed 32KHz crystal first

It was a long time ago but I did try and buy the Hugen version with the blue PCB. I just checked and it does say nanoVNA-H v3.3 on the blue PCB and the case and lettering are the same as the Hugen

AFAIK all open frame versions are clones. I have one that I have updated to the latest version of the schematic, works ok but there were some really weird component values originally. It would not

There are at least two members of this group who are confused about the NanoVNA-H4’s ability to write sp and screenshot files to micro-SD cards and what needs to be done by us to accomplish this

You need the Xtal only when you want to have the date/time displayed correctly. Jos Op 25-3-2021 om 09:43 schreef Rui Valente:

Hello I installed the latest version 1.0.50 and i solder a new SD card slot...them i tested 3 different sd card and different capacities but anything happen in the menu sd card (no error message)

Arie, It took me a little while to figure out what a balloon was. I passed the video and tried googling Ballon choke. But then it hit me. The videos are great. They are long but good.

I fix one problem in DSP code (for H version) in 1.0.50. H4 use DSP instruction and more faster/accurate in calculations DSP code for H: do{ int16_t ref = capture[i+0]; int16_t smp = capture[i+1];

Larry, Sorry. I meant capacity. I have a 32MB microSD card that I will try. Thanks, Mike N2MS

I also tried a very harsh test with the nanoVNA. I put two 820pF PPI 1111 caps in series and compared the ESR to just one 820pF PPI cap. In theory, the ESR should double and the Q curve should be the

I'm fairy sure my nanoVNA is an H as it had H firmware on it when it arrived. It was made in 2019 and is the open frame 2.8" model. At the time I did try and buy from a proven seller to get a well

Oops, for size, do you mean capacity or physical? It takes an microSD card also known as a TF card of any capacity? I've used a 32GB and 32MB without any problems On Wed., 24 Mar. 2021 at 7:10 p.m.,

I just got a new H4 form R&L Electronics and it has the SD receptacle. What size SD card does it accept? Mike N2MS

Hello DiSlord, T`hanks for the fast response, I reloaded 1.0.50 again and now it works... (?) I'm not sure what I did wrong before, but now it is working fine, its also much faster, which is great! My

See this topic (Now firmware can autodetect installed quartz, if no run LSI mode, time tick only while device power on) /g/nanovna-users/message/14447

For run/pause sweep need set/remove flag on Stimulus->Pause sweep On direct connect CH0 to CH1 port you should see S21 at 0 (if all work and calibration correct) on both port open ess noise at bottom.

Thanks for the information, Larry. Does the clock have to be working for the screenshot and s1p, s2p to be saved? Or do I just have to plug in a micro-SD card to get it to work? I guess the saved

Hello All. I have a NanoVNA H-4, and I have been using DiSlord's 1.45 SW for about 9 months. It is great,. it's stable and performed as expected. I recently discovered the new 1.50 SW and decided to

BTW,? have a look at OneOfEleven's nanovna-app program - it takes screenshots,calibrates the device and a lot more. The link is in her github account but you can find the link by searching for

In DiSlord firmware, the screenshot works if you click on the centre, bottom of the screen. You can add a 32KHz xtal on the PC14-PC15 pins at the bottom edge of the H4 PCB, then set using the time cmd
