Partnered Output Coils - Free Energy

[TinselKoala]

Yes, the Tek is nice all right, a real classic ... but the 500 dollar price and the fact that it does not come with high-bandwidth probes--or any probes at all--  means that it would come in at well over 600 dollars before it was usable. The LeCroy is out of the question altogether, that is more than my car is worth and it's just silly for someone like me to have something like that. I have considerable experience with several models of LeCroy scopes and they are fine, all right, and I'd love to have a 940 to play with... with probes to match of course, including a LeCroy current probe ... but I'll let someone else own them.

On the other hand, the Rigol DS1054Z comes with 4 adequate probes and has plenty of bandwidth for my purposes. Plus it is light in weight and will fit in my limited workspace and is easily portable. It does 1 Gs/s normally and delivers around 80 MHz of actual bandwidth to the 3dB rolloff. When "unlocked", as I hope the new production ones still can be, it has an astounding array of trigger functions, a deep memory, and digital decoding functions -- and 100Mhz bandwidth. The math functions are standard, as are USB and Ethernet connectivity. No floppy disk needed to transfer files or screenshots to a computer!

Thanks for the pretty pictures Wesley, but I'll be more than happy with the Rigol DS1054Z and its three-year factory warranty.

I agree that going the route of getting a new scope is better considering the amazing price and the more modern features.

I think the most important 'extra' feature is the USB port.  If you get really good at manipulating data with spreadsheets then you can do almost anything.  A typical example might be to export 8 waveform captures via the USB port and load them into a spreadsheet.  You can of course do all sorts of filtering and math on the waveforms.  Then Excel (or presumably the Linux equivalent) has incredibly powerful plotting and graphing abilities.  This is your famous timing diagram that most people ignore.

Here is a scenario:  Akula releases yest another circuit.  Someone replicates it and then captures a bunch of waveforms.  The data is crunched in your spreadsheet, and you produce a beautiful set of waveform displays.  The first waveform is your power or energy in waveform.  The second waveform is your power or energy out waveform.  Obviously both of these are derived waveforms.  There are 11 waveforms below that.  Eight of the waveforms are actual data capture waveforms, and three of the waveforms are derived waveforms calculated in the spreadsheet that represent critical intermediate-step variables that allow you to understand what the circuit is doing.  That would blow people's minds!

Excel has a pretty tough learning curve.  But once you have the proper spreadsheet skills, you can slice and process and display data like the proverbial hot knife cutting through butter.

You can envision Akula making a new clip and showing the circuit, and then a week later someone posts a .png graphic file that shows all 13 waveforms that simply blow Akula's claims out of the water.

Or look at a more simple example like TK referenced already.  Do an analysis of EMJ's circuit and show a sophisticated analysis with power and energy in and power and energy out.  Then produce the beautiful .png plot of all of the waveforms.

In my day we did this by making pencil sketches of the waveforms or taking photographs of the waveforms with a Polaroid camera.  We have come a long way!

Welcome to the 21st century TK!

Well
Tinsel is in a unique position at this moment...
we do have another home for "his" scope if he wishes to
acquire one of these?

I am sure the contributors would take no issue...
as long as the Koala is happy
?

No thanks, fergeddaboudit, see above.

How did we actually live with 1.4 MB floppy disks to export data from bench equipment?  Is the HP-IB /IEEE-488 bus still alive?  I remember how impressive it seemed but I never actually saw it in action doing something useful in my "bench life."  I suppose the 1.4 MB was a big step up from 360 KB.

Works for me...

Thanks for the input.
