So I can go the lowest to 10kHz with measurement of:
- my Tesla  coil resonances.
-any resonance circuit
My VNA or NA are   not the newest one but real goodies.

What I must compromise:
-everything below 10kHz.
 For that I use 4194A. that is ~30 years old unit, and nothing can be better in this price range.
   But..
             4194A is not VNA

So what is  the solution:
Here is quite tempting option:
https://www.advantest.com/web/advantest/products/electronic-measuring-instruments/r3755a-r3760
The R3755A network analyzer
Note: do not look at the R3760 network analyzer,

Where to buy:
https://www.ebay.com/itm/ADVANTEST-NETWORK-ANALYZER-CARD-R3755A/131555851726?epid=1225141993&hash=item1ea156fdce:g:KoUAAOxy4fVTAFNM
they have 4 of them.
But shop around before you buy.


6. software source:
https://www.advantest.com/web/advantest/products/electronic-measuring-instruments/r3755a-r3760
  on that page  click on button application
  go down  of the page to Firmware and read if the software is right for you. 

This is nice modern tool( ~2012) made by  reputable manufacturer
                   but again starts from 10kHz..... to 300MHz
                   so after you buy it and it works  you can't go lower than 10kHz

Wesley,

Also can one use a frequency divider in order to go below the 10kHz or do we get too much impedance loading with low frequencies for such a solution to be practical?

I think there are multipliers to go the other way but likely one has to give up something to get like SNR or dynamic range...

Microwave has been known for wireless charging way of rectenna for years, just keep the beam width tight but it is still lossy except for near field loose coupled resonance, if one can parallel keep high Q and get eventual gain but major pain.  There are more tricks of the trade like anything but for a drone is not efficient use of energy.

Wesley I was interested in which you reach for more often impedance or VNA, just curiosity and in the case of the impedance analyzer how do the in and output impedance work if not limited to 75 ohm coupling, I have never used.

I can do quite a bit with VTVM bare bones so yeah I know I don't need this gear and already have some good stuff for my audio business so may not bother.   Just would be cool to have some RF gear to help with antenna design.

Thanks again

Let's go to: https://www.youtube.com/watch?time_continue=4&v=A58auF2dhCQ
The interview  is with : Leonid Plekhanov CEO of Global Energy Transmission (GET corp since April 2015.) established in  2015.
But patent application  is filed as company ( not as corporation,)  with 2 years later date. 03 17 2017.
So it looks like These Russians,  did not close their company,prior to opening corporation
and in USA company  can be you, and you, can be company.
Company is your "second last name" if you will.

So  that Patent Application  is not property of corporation unless stated.

Step1 measuring of real  structure  of Tesla   coil with VNA

We have been talking  about VNA and NA

 step 3 - 3aa. measuring of real
Tesla  coil structure with VNA

Literature:
page 3-9
page 3-10
https://www.advantest.com/documents/11348/146687/pdf_mn_ER3754_user_MANUAL.pdf
So one simple measurement and you know everything about   it.
It'll save you days of work .
So is it that simple?
Yes and no.
It is  simple but there are some variables that can not be solved by use of VNA.
example: your load ( output) is measured as if it was 50 ohm.
So you can connect in real  test few lightbulbs in series to compensate for 50 ohm.

And that's another discussion.

step 3.aaa measuring of real
Tesla  coil structure with VNA
Note: Attenuator is needed , but:
a. it is good to measure output voltage of your VNA
    or check what is the voltage it in manual.
b. Than prior to use VNA, connect tracking generator from your spectrum analyzer  or any sweep generator
    to primary of Tesla coil and at secondary connect your oscilloscope.
c. find frequency that has maximum amplitude on your oscilloscope.

d. based on this measurement you will know already  a lot about  your Tesla coil and you may not need  VNA.
    Voltage present in secondary of  Tesla coil will allow you to  get proper  attenuation required  by manual of your VNA. 
e. generator of  your working prototype should be tuned to red region of frequency generation

VNA

Some  of the VNA have been made for production line of X-tal
crystal oscillators.
And they have build in more tools to
measure  resonators and  resonating  circuits.

Tesla coil is:
- air transformer
- resonant transformer
- can act as filter

Assembly made of coils and capacitors can be treated as  one DUT
(Device Under Test )with single input and output.example of possible measurements is listed below:

Conclusion.
That what was taking months  and years now can be done in few minutes.
Most of you are happened to dig in the dark  for years, and VNA is your pair of glasses.
But you need some flashlight too.
I do really try, to provide it for you guys


Device made by you,  has one purpose, and that is Electrical Energy for Free
Such  a devices are exotic as:
 - scientific base of energy origin is questionable.
Note:Wesley provided  explanation, in this  part of forum.
 - prior art  exists  mostly in form of unexplained pieces of information
 - any device that is made for any purpose must be replicable (able to be copied or reproduced exactly.)

Note:
on the picture below
  -any time crystal resonator is used for our purpose you can use word  filter
   and Tesla Coil can  be our filter .
  That will analyzed in  next  post.

Wesley,

Yes yes the VNA is better than graph paper and a a scope and mush guessing in the dark from all the interactions of RF.  OK I ordered old HP for few hundred bucks, hope it gets here and works, of course it will not be aligned so next I must ask do you think it is necessary to have the alignment kit or to just to rent ?   This unit supposedly goes from DC to 2 gHz and i don't plane on working more than a few mHz aside from that old 300 mHz battery we discussed if I ever get back to it.

Also a large expense are the probes, what does one need to work up to a few mHz besides some very good coax and connectors for the DUT?  I have heard that using the BNC to SMA adapters and some premade SMA cables can work pretty well, your thoughts?

Thanks,
Mick

Wesley,
As always digesting the very good info you post and the Smith tube video is super cool!   Thanks for all the charts and explanations.

Hey someone obviously wants you around.

Can I ask what it was you did in professional life, or is this too personal? 

Thanks again,
Mick

Thank you for kind words.
Before you pay for VNA or NA.
some pros and cones.

https://www.youtube.com/watch?v=LN9PKKdFibo
note:
-Calibration kit can be any.
-look  at second picture.


some additional literature:
http://www.rfwireless-world.com/Terminology/S-Parameters-Scattering-parameter.html
http://www.antenna-theory.com/definitions/sparameters.php

Question is:
Do you need S parameter?
No you do not need S parameter but is good to have it.
And that  gives you a lot of room to hunt for used VNA or NA that is  not compromised  like  VNA from video.
