I have access to some very sophisticated equipment - VNA, spectrum analyzer, more.
I don't use it, but could/may - and I have someone to watch over me so I don't damage it.
How can this equipment be used for optimization of the coil design for PI detectors?
Say you were to use the SurfPI design we all know. Seems we are all trying to duplicate some inductance recommendation but I want to understand why and if its valid/optimal.
I'm assuming there is a tradeoff in tolerable current draw for the TX and number of coil turns per coil diameter. Then on the RX, increasing the number of turns increases signal but also capacitance and pulse decay artifacts. (right?) I'm wondering how then, when our TX signal is just the pulse, such equipment would help.
BTW, if a VNA can help there seems to be a popular one in ham radio circles available as a kit for a few hundred dollars. Curious if it is good for us, what minimum frequency range should be adequate.
