Q:Warning! Меня человек предупредил по поводу данного видео: "
Эта лампа сильный источник гамма излучения, играться не рекомендую.
С фиолетовыми излучениями предельно осторожным надо быть."
_{A man warned me about this video
This lamp is a strong source of gamma radiation,
I do not recommend playing.
You should be extremely careful with violet color radiations.}

Oтвет:
Kаждый разрядник генерирует рентген,( X-ray)
_{Every Spark Gap creates  X-ray
Striking one stone by another stone creates X-ray.}
я не согласен с вами что эта трубка разрядника создает гамма.
Это абсолютно невозможно. https://en.wikipedia.org/wiki/Gamma_ray#Gamma_ray_production
У меня есть целая лаборатория физики элементарных частиц.
Но вместо того, чтобы спорить с вами, допустим, что вы правы, так чисто теоретически.
Если вы правы, говорите как ..?
Я уверен, что у вас нет ответа.
_{Each Spark Gap generates X-rays, (X-ray)
I disagree with you that this Spark Gap tube creates  gamma.
It is absolutely impossible.
Some spark gaps have been doped with  CS137 and so on.
But that has nothing  to do with generating gamma due to its Spark Gap operation.
I have whole lab of particle physics.}

Wesley,

About to buy either a new cheaper spectrum analyzer or an older circa 2000 VNA.  Was wondering if you have a VNA with FFT capability from the era I see in your rack can it substitute well for the newer higher memory Spectrum analyzer with partial vector analyzer capability? In other words can you use your VNA for most of the SA functionality to the effect you would reach for this tool?
Also have you happened to find any option to allow power factor calcs with a VNA if one has a differential probe?  Some of these units look to have two inputs which beats a SA with a tracking gen.

I have been using the computer interface Spec Analyzer and just need a dedicated unit so thought these era 2000 units might be better with less memory but the ability to properly impedance match with a Smith charts and correct VSWR calculations. 

Thanks,
Mick

In here I have 3  but actually two of them
( the third one is 4194A Gain Phase Analyzer this is great toy.)

R3754B  starts from 10kHz but it  goes up to 150MHz if needed
Faster than anything  new I have tested in the market.
Just "lightning fast"
in addition I have Impedance  parameters program similar to  LCR that was used by previous owner.
Some kind of exotic  luxury option.
here is the spec.
https://s3-eu-west-1.amazonaws.com/content.microlease.com/static/Catalogue/Datasheets/Advantest_R3754B.pdf

-HP 8753D 30 kHz to 3 GHz  but I have 6GHz version.
http://www.testequipmentdepot.com/usedequipment/hewlettpackard/networkanalyzers/8753d.htm
I must correct some information. from the previous post.
_{8753D Network Analyzer has a frequency range from 30 kHz to 3 GHz, which can be extended to 6 GHz with
Option 006, a resolution of 1 Hz, power range of -85 to +10 dBm, and a maximum input level of 10 dBm.
This model has a built-in S-parameter test set, which gives the user forward and reverse measurements, enabling
them to fully characterize their instrument with one connection.

4194A gain phase  analyzer plus impedance it starts from 10Hz.

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:

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. 

<sub>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...

Not generation but wireless charging,  over kilometers :

This thing is 70 years old concept.https://www.youtube.com/watch?time_continue=4&v=A58auF2dhCQ

[mkjekyll]

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.

 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.
