Thanks for the segment suggestion Rune and those off line too, I don't think it was the segment issue. It seems the callibration data had somehow been borked and nothing was correct, once did the 'cal

Hi Norbert, For calibration within NanoVNA-Saver, setup the sweep first to be the span you want calibrated - for example, 50k to 1500M. Then in the box labeled "segments", enter how many segments (of

Hi Rune, thank you very much for your quick answer! Please tell me the trick where I can change the number of points prior to calibration. I didn't find that yet. I think the following measurements

Hi Norbert, the application can run calibrations at far more than 401 points - I have certainly done 5050 points at one point. ;-) But it does this in the application, and not on the device, due to

Hi Rune, thank you for fixing this issue! I have a question for you in respect to the required number of data points to measure a band pass filter. With 101 points it is most likely not possible to

Thanks Rune, I'll try both options. BTW this is running Linux & Python 3.74 version at home, work is much earlier so will have to wait I guess until later. I get the same output with the previous

Glad you got yours. Obviously I'm not worthy. I have got one now from elsewhere on eBay. And when my sma to n adapters come I may even use it!

Nice idea. I wonder how long those little u.fl connectors will last though.

You tried sweep 50kHz span with 101*10 sweep. I don't think NanoVNA capable below 50Hz RBW... How about give more span with default 101 sweep?

Oh, a different issue: You set the segment count far, far too high (1000). Try a value of 1 first, and see if that helps :-) -- Rune / 5Q5R [email protected]> wrote:

Hi Dom, The application is receiving some weird data from you device - a value of about 2 billion, which is supposed to be in the range -1 to +1. ? Try doing a full calibration on the nanovna,

Of course Larry, you've been a great help thus far! :-) I'll be doing alpha testing for each new version from here on. -- Rune / 5Q5R

Chinese holiday now

You have the test signal from the SI5351 send to the bridge but also to the "reference" mixer, in the reference mixer it is mixed with the output of the Local Oscillator (LO) which also comes from the

I cannot get this to work on startup using nanosaver and I get in the logfile ... 2019-10-03 07:33:37,745 - NanoVNASaver - INFO - Startup... 2019-10-03 07:33:37,829 - NanoVNASaver.SweepWorker - INFO -

From: Oristo In reality, USB does not work that way. Here are "real" supported USB speeds: USB 1.0/Low-Speed: 1.5 Megabits per second (Mbps) USB 1.1/Full-Speed: 12 Mbps. USB 2.0/Hi-Speed: 480 Mbps.

Hello gin&pez I installed maxima and ran the visualizer, it worked OK giving the expected figures. I have also taken a look at the fortran code, and I am not done yet, it is difficult to read as it is

Oristo, I think I found a message string that may help explain your results somewhat Kurt Poulson at Sep 9 message #2140. and the ones that follow it. Jim, KA6TPR ?
