Hi Mark,

I defer to your expertise.  I am mostly just speculating.  I took a course in numerical analysis and I barely remember the different approaches for interpolations and stuff like that.

In very simple terms if you are digitizing a linear ramp function and you get something like this:

142
142
142
142
143
143
143
143
144
144
144
144

Would there be a standard spreadsheet function to interpolate on the data to "remove the jaggies" and turn that into a series of points with a smaller step value?  I am assuming that you could also put a low-pass digital filter on that also.

If you did that I honestly don't know if it would give you a more accurate power measurement system.  If anything though, I love the thought of taking the 8-bit A/D data and being able to display it on a high resolution monitor as a bandwidth-limited perfectly smooth waveform.  That would include standard algorithms for computer graphics displays where some pixels are darker than others (sub-pixel interpolation) to create the illusion of a smooth curve, etc.  For all I know this is an option in Matlab.

One could interpolate those samples by effectively adding K_{INTERPOLATE_SINGLE_VALUE} = 1/n_{SAMPLES_AT_SINGLE_VALUE} and adding K*n to each value.

142, 142, 142, 142 n = 4, K = 0.25, 142, 142.25, 142.50, 142.75
143, 143, 143, 143 n = 4, K = 0.25, 143, 143.25, 143.50, 143.75
144, 144, 144, 144 n = 4, K = 0.25, 144, 144.25, 144.50, 144.75

Sinx/x interpolation is used in many DSOs including the Rigol DS1054Z.

Here's an introduction to interpolation in digital scoposcopy:

Yes I understand that there is a lot of power in the scope.  I just think it's worth it to think about the spreadsheet as a very powerful tool also.  All in good time, I am not suggesting anything beyond just illustrating an example of what could be done for now.

One thing about a DSO that I think is worth mastering is trying to sample your waveform at the highest rate possible.  I notice you often see that the "data buffer depth window" shows that you are looking at a tiny slice of the memory buffer.  I don't have the skills or experience, but what is always in the back of my mind when I look at those displays is how many raw data points have I captured for my waveform.  Note that what you see on the display is typically a "crunch down" of your data buffer and since I don't have the skills to drive the machine I am always in doubt.

I will put it in simpler terms:  You see a waveform on your scope.  It's taken for granted that you are oversampling the waveform.  The display is 800 pixels wide.  Are there 15,000 samples that were crunched down to render that waveform into an 800-pixel-wide display?   Or were there 942 samples that were crunched down to render the waveform into an 800-pixel-wide display?  That's were I feel uncertainty and that's where I always want to know.

Of course there are diminishing returns, 200,000 samples vs. 15,000 samples is not going to give you anything.

For spreadsheets, here is just something to ponder:  You have a highly oversampled waveform and we know the A/D is eight bits.  You can take that data buffer and filter it in your spreadsheet and completely remove the "jaggies" and turn it into what looks like a perfectly smooth waveform.  So the output from the spreadsheet could be a butter-smooth highly oversampled waveform that is say a simulated 14-bits of precision.

I am no expert here but here is my train of thought:  You want to make a very advanced high-precision power measurement.  You take two raw highly-oversampled 8-bit waveforms, and smooth them out and get two "virtual" 14-bit waveforms.  Then you do the math on the 14-bit "near-zero jaggie" waveforms and output a butter-smooth set of power and energy waveforms.

You might only want to do that once in a while when there is reason to do it.  The point being in a way you can "overcome" the jaggy 8-bit A/D by oversampling and filtering your data and then you work with these derived waveforms.

Correct me if I am wrong, but this is what a high-end sound card does with its on-board processor.  It calculates intermediate values between samples to produce "smoother audio" at a simulated higher D/A bit depth.  The sound card creates virtual higher precision A/D data and a virtual higher precision sampling clock before clocking out the data into say an 18-bit D/A chip.  In the case of your DSO, you don't really have to do any virtual oversampling because your sample rate is already super high.  But the "smoothing" and simulating a higher A/D could come in handy when trying to make more precise power measurements.  And like I said, then you get "prettier" waveform plots that are free of the jaggies.

Finally, I think this is mostly valid.  You can generate derived smoother waveforms because that is what is actually happening in real life.

think about it  different way.
1.the higher the sampling rate the better is accuracy of the trace.
2. it does not make any difference   what is your  resolution "of the screen " on your crap  Chinese junk or good 20 years old  american made. All of the sampling point will fall into the right  place on the trace,
However it is good to have high speed of the processing of the sample point.
That is why they invented  digital storage oscilloscope  to compensate that problem" in old times" for slow computing power.
surprisingly Chinese  crab:
- is designed to look nice,
- is designed to live  short
- is designed to be "economical" cheating, stilling, copying with bad quality  modules  and processes.
- is designed to be not rigid as in that price range they will fill the  low market with junk ............and than what?

If you go to this page  all you find is  very old american made digital storage oscilloscopes and new Chinese  junk.
You may ask yourself why is that?
is it because Chinese have hard time to use modern  american electronics?
the answer is NO
Chinese can be as good as American are, but Americans decided that the cheapest Asian labor can make the best   devices  with brand name and they still will make money on it.
anything that  is cheaper than that must be just in the shadow as most likely Asian junk with Chinese quality of assembly.

one may ask by looking at that page:
why?
why there is on that page with old storage  oscilloscopes  -new BK Precision 2530B 25 MHz ? well the answer  is simple, BK is no loner american. Also  it is so low end  for as much as name could allow  it to sale.
It use to be nice competition  of BK, BNC , Keithley  no longer true.




Many of you are happy  from being able to buy  some nice  display  futures for cheap.
Yes it is true. they are getting better and smarter.
but you guys are happy from the  fall of Western World Domination and 2 billions of Chinese stilling a job from only 308 millions of american




guys wake up:
There is nothing left  here.
1.America is country of 13 millions of  mostly Mexican illegal emigrants and 50 millions of former south america citizens.


2.America is country of  maintenance people. electrician, plumber , construction  worker - who uses Chinese  made tools.


3. Many
or
Most of them
is some areas  100% of  them are using american social help system as way of life.
"not existing husbands " of the every year pregnant woman , who crossed  the border
they getting   thousands of dollars   of help for single mothers with  children.
and "non existing husbands" coursing with nice cars and  loud Spanish music  around the city, possibly trying to impregnate more  illegal Mexican woman for social benefits.
That is the reality of life  many can notice.


many of them or all of them  think not about free energy, but about easy life  while listening to LAMBADA or other Spanish exotic music with 1000W amplified speakers buzzing out 
from open hood of the  nice cars.



some of explanation to point #2
I have been  near Chicago,  in Motorola facility 5 months ago, empty humongous, made out of  glass building
-Very difficult to go around it with the car.
-Number  of  gates , local " backyards" bay areas, tennis courts, few  playgrounds  for kids, and so on
-EMPTY  5 thousands cars parking lots ( around 3 of them)  with grass growing fast out  asphalt.
- in one of the gates after 2 hours  of cruising from bay to bay I saw signs of life.
-I was told that, GOOGLE purchased MOTOROLA only to sale it to CHINESE with profit.
-there was plenty  of equipment sold for scrap,oscilloscopes, machinery, lab equipment, production lines - you name it. I got parts and software for  electron microscope for $35, the value of it  say it, was more than 100k( new equipment  price)
-I was told that nobody from China want the building  or equipment  all they need is the name.
I was told that minimum 5000 jobs have been lost and part of   activity moved to Motorola inside the  city that will close soon.It is just political move to ease out  pressure. China decided to pay to former workers double compensation for lost jobs.


for few moran's  that can  accidentally read my post I say:
5000 jobs  is x3 ( mother and 2 child) 15000 houses, households, apartments,
Someone will say it is an error in calculation.
think this way:
Many of the children are about to start their own life with no money for continuing education and buying their own house.
Many of the families will divorce .
and I was counting only  mothers with 2 children( no husbands yet)
e.g.  two daughters of one family will need two apartments for  themselves and their new families
I think I got close approximation.

there is number of stores that will never see sale for 15000 people.+5000 husbands who lost a job.
Cars,  traffic tickets, taxes,  gas and electric charges  , business activities, foreclosed houses ,Human life in ruin


How many peoples are suffering?
that is that much less for economy

and government must feed, and accommodate ,  these families till some of them find another job
and there is no job for many.

Got it?






and now we have that  :

So soon there will be possibly  a lot of junk you can be" happy" to buy
If you still have money to buy  any food.


The American Greed  chock up itself to the near death.
the power is in hands of Rich and Powerful  and governments are their  puppets

Pretty high quality "junk" I think, and comes with a three-year factory warranty. And a certificate of calibration.

It is american investment with some of american technologies that rigol was allowed to use.
With time they will become very powerful and good.
With that, the same number of high  quality american equipment will not be sold and proportional number of jobs will be lost.

EEVblog  works also based on donated/ for evaluation equipment  in exchange for  "evaluation"
How he can say wrong  about it.

He also made video about Free Energy
And my comment  was blocked , my  email was not  not answered.

that is your truth my friend:

this guy pompously and purposely chosen unfortunate guy to scrutinize. It was so easy for him to  make more money on commercials.
Why he did not take TK or AKULA or RUSLAN   or SR to play with?




the answer is  he is not skilled enough !!!!!!!!!!!!


My friend TinselKoala
what kind of people   you throwing  me  to talk about?
He is smart?
Yes in some areas but in other areas , he is just average Joe.
There is no universal brain.
that is why we are here on this forum helping  each other.




this guy makes money based on commercial in his videos.
Few years ago he was complaining  that it would be good to have 50 000 subscribers.


He must also have very "politically proper" opinion about FE.
