I would solder the coax shield to the area labeled GND in the antenna design, not to the ground plane nearby.

Hi Dianne, What model/version of the nanoVNA do you have? many do not cover the 2.4GHz bluetooth frequency band. What diameter/type of coaxial cable are you currently using? Type RG316 has diameter

Thanks for your reply. I managed to correct the delay I was asking the same question to my tutor about the size of the cable in relation to the PCB. I am on an internship and I have to design a PCB

Hello, Thank you for your answer. My DUT is a PCB trace antenna. Attached is a picture of the antenna. I need to perform the measurement in the feed line of the antenna. I am in an internship and the

Hello, Thanks for your response I've got -462ps for the delay correction is it good? Best regards. [email protected]> a écrit :

The most accurate way is to calibrate at the end of the cable using a short, open and a 50 ohm SMD or very small resistor with absolute minimum leads. The other way is to use the electrical delay to

What exactly do you want to measure? What is the Device Under test, DUT? Is it the PCB? Is it the cable? Is it the combination of the two? If you just want to measure the PCB you need to do the

You have to calibrate at the cable end with open short load And with such big cable soldered to such a tiny pcb your results will be at least questionable... On so high frequencies even an sma to n

I bought my NanoVNA in large part to have a solution looking for a problem to solve. My main use for this device was the SWR sweep capability for my antennas, but I soon discovered previously unknown

Theory is always incomplete. It is said that the field of thermodynamics learned much more from the operations of steam locomotives than steam locomotives learned from thermodynamics. Often electrical

Hello everyone, I am a beginner in using the NanoVNA, I have a calibration problem after connecting a transmission line into the VNA. You can see some pictures of the result in the attached document

Hello Ed, Op vr 15 jul. 2022 om 11:23 schreef Ed G8FAX <ed@...>: Thanks, but when I get a better grip on the OCFD (aka being ableto model and include in that moe the Choke) I plan to

Hi Victor, Oh wow, what a fantastic webpage you have, full of useful information. Your attention to detail, investigations and experiments is exemplary and I congratulate you for all your efforts. I

If the "practice" is not in agreement with the "theory" it is that there is an error (a fault) in one or the other, to see in both. -- F1AMM Fran?ois

Thank you for your prompt reply DiSlord! I much appreciate your extraordinary initiative and hard work to support the NanoVNA.

Thank you all for comments and criticism. I have always been a practical and experimenting man, sometimes, defying theory

Hi Francois, Thank you for your contribution. The image you refer to gives a method for testing aspects of a 4;1 voltage balun, see link in the other ref you provided http://vk6ysf.com/balun_4-1.htm

Hello Ed, I mostly do CM0 measurements on Chokes, but I checked the OC one to see what it did. I think G3TXQ used OC, but not 100% sure (he does not fully describe his setup in:
