Allow me to take a stab at this and try not to introduce too many new issues. 1) The 'phase' can be viewed as the 'delay' between the input signal and the output signal. When considering scattering

That reference (below) is excellent, and clarifies everything! Thanks, Roger.

Hello All, Need a question answered here. I am the one here making a new set of coils for a Heathkit SB-220. Using A NanoVNA-H4 I learned how to measure the old coil values. And what the stimulus

From the beginning: Many of the questions that appear in this forum regarding VNA operation suggest the fundamental premise of the VNA is either missing, misunderstood, assumed, or ignored. Questions

Andy, Here is a link to an excellent paper by Olivier Pilloud HB9CEM which describes the relationship between the reflection coefficient Gamma (Γ). complex impedance (R+jX), Return Loss and VSWR. He

Wonderful! Thanks, Jean-Roger

Andy, Below is a copy /paste of my answer to another old thread. It could be of interest for your question 3. REAL and IMAG parameters are not the samething as RESISTANCE and REACTANCE parameters.

The group has a very well built wiki. Please read it there as well. If this seems like a lot at first reading because your problem is hard to put on any description, set it aside for a while, read it

Thanks, Dave. Note that the images you sent did not come to me, only the place-holders (see below). Also, I may have been unclear. I totally understand that resistance and reactance are quite

1. “Phase is the relative phase difference between source and received signals.” What does this really mean? Is it current to voltage phase, or change in that as influenced by the DUT, or simply

1. Voltage, Output vs Input 2. Takes more time than I have to explain. 3. Ditto. 4. S11 and S21 are ratios (dB actually, which is really just a ratio) of voltages. S11 = 20*log(Vreflected/Vincident).

I have been through the Wiki and got some answers, but here are some questions about the output options on the nanoVNA-H4: 1. “Phase is the relative phase difference between source and received

I can't write or debug software for units I don't have I'm afraid (I don't have a V2plus4), it's like trying to find faults on a car you don't have or have never seen, you need the car there with you

Hi, A great effort, OneOfEleven ! Apologies in advance if this thread isn't the correct place for this question though. I have a NanoVNA V2Plus4 (build 20101013, v1.2) and cannot successfully run

Very thanks OneOfEleven !!! Enrique LU8EFF

Hi Albert! Here are some pictures of my test jigs... Karl

Nano's have very narrow downconversion bandwidth so not too vunerable. But, do you happen to have a UHF TV ch 33 transmitter nearby.

Works fine !! Thank you so much OneOffEleven. Jos Op 8-9-2021 om 18:03 schreef OneOfEleven: -- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware.
