Thank you GIN & PEZ -- 73 Gary, N3GO

it's not clear what you're expecting and what is wrong... Could your please explain? In general I see some issues with divider: 1) Two 20 k resistors leads to 40k continuous load on the battery. So,

I used resistors to make a voltage divider, and tied the 20K across D2 and the 100K from D2- to C47 gnd. In the attached image, currents with VBATEN on and off show 60 and 35 uA, respectively. One

Rune, I'm still hoping someone can help me understand the new TDR impedance measurement display ( see message /g/nanovna-users/message/6520 ). One other thing in regards to the TDR

Hi Rudi Understood, thank you. UPS about the R&S TR-Check have you tried to run in W95 compatibility mode and as administrator ? Kind regards Kurt -----Oprindelig meddelelse----- Fra:

Hi Sam, you're welcome :-) I have considered interpolation; but my original idea for the software was to allow more data points to avoid interpolation, and instead provide better data resolution. For

Rune, Thanks for the new version. Has anyone given any thought to using interpolation to display the data between the measurement points when in line mode? Sometimes more often than not there isn't a

Hello Kurt, Yes I know that the curve is not so very good. But it was just a priciple test for the procedure chain: NanoVNA-saver .S2P file save to a T-Check curve with minimal effort, with free

Hi Erik Thank you for the spreadsheet I did mistakenly comment your T-Check to Reuters and did right away see the mistake I imported your s2p file after modification of the header, as a surplus S at

Hi Reuter I had to modify your header to import the s2p file. There was a S too much ! ListType=Lin (This addition was probably not needed) # HZ S RI R 50 (at the end of this line there was a S too

Hope someone can give me some insight on the TDR impedance measurement display. I have attached TDR impedance displays for two cable assemblies. The first cable assembly was made up of a 0.3m length

Thank you, that is usefull information for everyone! I haven't decided what to do. I might fix my nanoVNA, buy another or wait for the announced "nanoVNA 2.0". My version isn't completely dead but the

Eventually, but getting something built first in a "friendly" IDE, then whittling to fit, might be faster. Also, with Bluetooth, local display becomes highly optional.

Hello Erik, Now it works, see the attached diagram: NanoVNA_T-Check.png Thanks again for the very good spreadsheet. 73, Rudi DL5FA

Actually, read the whole thread, including /g/nanovna-users/message/1795 With all the features stuffed into the current firmware, builds are starting to overflow storage. You'll need
