For those of you who didn¡¯t like my first two attempts at this video.. I think I¡¯ve done a much better job on this one of explaining why I take my readings at 90 degrees phase angle on the smith

On H4 this can be from default color on H4 for LC/Match (all colors can be changed by color command) You need: Run in console command for change LC match text color: and not fogot save CONFIG->SAVE or

nanoVNA - Measuring the resonant frequency of a crystal #measurement #tutorials #video
A video I did up last summer on how to use the nanoVNA to measure the resonant frequency of crystals. The intended audience is those who are not wanting a complete and exhaustive characterization of

Re: NanoVNA Testboard kit VNA Test Demo Board #applications
The boards are very similar. I have not seen any documentation online for the six-connector board. What is different is that two additional sections have been added so that you can build attenuators,

Re: nanoVNA - Measuring the resonant frequency of crystals #tutorials #video #measurement
Raoul, If you are interested in more info on measuring crystals with your NanoVNA I suggest the video by W2AEW on this subject. He carefully explains the terms and definitions and compares various

Re: NanoVNA Testboard kit VNA Test Demo Board #applications
I received this same six-connector "NanoVNA Testboard Kit" with my VNA. Where can I find documentation for this kit? The documentation link in this thread is for a different two-connector test board.

Re: Hardware deficiencies when measuring high impedance with S21
This just became a bit more interesting. It seems that there is a discrepancy in how SimSmith calculates the angle depending on the circuit block used. For an S block it shows the same curve as in

Re: Hardware deficiencies when measuring high impedance with S21
I guess that depends on what you consider as minimal and if you are modeling an ideal resistor or a more realistic one. For example: on the first image is the plot of voltage angle at the load (port 2

Re: PROCEDURES for MEASURING DM LOSS and CM ATTENUATION of CMCs
I would presume type 43 material is used? For 160 and 80-meters your setup is quite reasonable. If you scanned to 30 MHz, likely a clean-up would be required, but you are aware of that. Good work!

Re: Hardware deficiencies when measuring high impedance with S21
Dragan, Thank you for clarifying what you did on your tests. I took a look at the .s2p file that you posted and see that you get the same large S21 phase shift that I got in my tests. I posted my plot
