1.2.5.3 CABLE S11 Choose a frequency range such that the cable length is ~1/4 of the wavelength in the middle of the range. This feature uses velocity of propagation. It automatically measures the

The first suggests to me that each of these measurements needs its own threads, here or elsewhere. And that is for each used who wants to do those specific types of measurements. The second, however,

The attached diagram shows the cascade (or not) of calibrations when using the NanoVNA with internal cal (or not) and a PC app cal (or not).

Someone should make add on cards with those protection diodes. I wont solder them myself, 0603 are hard enough and sometimes even a 1206 between two SMA connector PCB pins.

Hello, Making a model reproducing the 45MHZ pass filter of the ubitx (but with variables capacitors) and connecting at each end a toroid transformer I managed to improve the tracing of my filter. Or a

What a gold mine! Thanks, larry

This is why I generally avoid the use of lower case "L" unless the meaning is clear, or I can use a font that makes s clear distinction. Simliar reasoning applies to the letter "O". In this case, I

Good point. I was not expecting a lower case letter here, so I interpreted that as a 1 on both the -H and the -H4. Even in email, I can't always tell, depending on how the font is shown. In this case,

I see only Rl = 50 (not 1 and not j) You must read how made XTAL measures and another: /g/nanovna-users/message/25800 /g/nanovna-users/message/25801

Hello Roger, The same documentation is also in the groups *wiki* /g/nanovna-users/wiki/16592 or search in the groups wiki for the word *NWDZ*. /g/nanovna-users/wiki

I just got a NWDZ board in the mail. Hope to take it for a spin this weekend. Here is a link to some testing done on a NWDZ version by a fellow in Germany... >>>

I find that I often want to replace a saved cal, but don't recall which one. I then backtrack to Recall, and if I am busy, I write down which one I want to replace. Then off to the cal, and save. But

Thanks for chipping in DiSlord. If someone here can explain how that is to be used, I'm happy to put it in the docs. My -H4 has Rj = 50 My -H has R1 = 50 I am guessing those are the same? We also have

Port Z option not public on my github, so not avaible on Hugen firmware. Only on my tests fw variants. On Measure page Rl used for XTAL measure

A few weeks back, I wrote because I was not getting the results I expected from my measurements. I replaced the cap and coil with "known" values, being more careful with those tiny

Which version of firmware and what model(s) are you currently using? It is helpful to know because users in this group are running different versions. Roger

This is what I hoped to see...thanks for the notes following, too, though I was generally aware of the material. In earlier DiSlord docs, there is mention of PORT Z 50 -> XX, but it is not on either
