are any of you electronics experts?

if one was going to tinker with/research scalar waves -- what will be the specifications and recommendations for capable oscilloscope?

all i know is that they come in different shapes and capabilities.

what is the minimum megahertz range that a scope needs to have for research of scalars/EMF and such?

can you "science me" on this question.

I did electronics at college, forgot it about 3 weeks after finishing lol. They're pricey as fuck, unless you go to a college and buy one off them. You'll be looking at very low frequency, 0.1 hz, humans are around 10hz, electrical equipment 50 hz, so nothing too high if you're studing effects on humans.

Yes, I'm experienced with electronics. You would need to build a scalar detector, which in turn can be connected to an oscilloscope.

This might help though I can't verify it.

Now a scalar wave only has magnitude so I expect the voltage to be proportional to this magnitude. I suppose what you see on the oscilloscope depends very much whether the wave is modulated with respect to time. If the scope is set up wrongly you will still see a signal but it will just be all fuzz. As you flick the frequency knob and adjust the trigger setting you can then get a waveform if there is a dominate frequency the trigger can latch onto.

Do you know how to protect against scalar weaponry/waves Baron?

ok, that is what i thought -- the scope does not have to be high end for scalars research.

BTW, what is megahertz bandwidth specification of the scope?
would that be actual maximum amplitude of the input or does it reflects something else?
and, is this specification per channel or is it combined
for 2 or more channels?

or, is this rating reflecting the frequency of actual input.
in that case to measure 2GHz frequency you would need a scope that is rated at 2 Ghz.

sorry, but i am really confused here as some low end scope are say 20 Mhz, higher end scopes go into GHz range.

would you need a scope with greater range than 20 Mhz for this kind of research, taking in consideration that you may want to do research on microwave energy from cell towers and various other EM pollution sources?

I know a bit, did a BTEC in electronic engineering (never finished it tho)
but i know nothing about scalar waves so if you post some info i can tell u wat kinda scope you want

Cheap scopes work up to a few mhz. There are two different types, the analogue scope that simply works like a TV screen, where the signal is used to deflect a spot in a vertical direction as it is moving from left to right and then there is the storage scope. The new storage scopes digitise the input with an A-D but A-Ds are still only rated at a few mhz unless they are for video and then the accuracy is only 6 bits. The scopes that work upto GHz are only for periodic waveforms and they work by sampling say one every hundred oscillations or so but rely and assume the signal is repeating.

so, what do you recommend - analogue or digital scope?

[baron von lotsov]

Just get a 10mhz single beam one second-hand for a few quid unless you want to use it for lots of other things. You can pick them up as MOD surplus and they are built to a very high quality but just a little old. All you are really using the scope for is to gives you a magnitude of the scalar wave unless it is modulated. If so you need a scope to go up to the modulation frequency. So it all depends on what you are doing but nothing would require a really fancy one that I can think of.

here is the link to different type of scalar measurment methods

I like to try Bedini , FM TFD variation or anything in between.
kind of learn as you go approach.

but, i'd like to use scope for other applications like troubleshooting of electronics.
something that is portable and that can store the data to say an USB drive would be nice.
maybe something like this

http://www.tequipment.net/Fluke192Bscope.html

i am considering the following models:

TDS1012B 100 MHz 1.0 GS/s 2.5 K 2
TDS1002B 60 MHz 1.0 GS/s 2.5 K 2
TDS1001B 40 MHz 500 MS/s 2.5 K 2

what do you think?

[baron von lotsov]

Yes that Fluke one is a nice piece of kit. It samples at 200mhz and that is why it is so expensive. You don't need something that good unless you are working with extremely fast electronics. 10 mhz is all you normally need and if you want one to interface to a computer you can just buy an ADC with the interface you require.

I have had a look and these two seem about right and a lot cheaper because it is all done on a laptop. You get a nicer screen that way and at 1/5th of the price.

ok which experiment are you looking to recreate?

and by TFD do you mean Thermal quantum field theory ??

something like this would suit you,

you got me back into it now lol i was building a electrolysys machine for my car, couldnt get it past stage 1 and then i cracked the clear acrylic end plate, i heard the resonant frequency (most efficient at splitting water molecules to make hydrogen and oxygen) was 28Khz i used me PC and my amp to try but it only goes up2 22khz, but i would be interested to see what would happen if i added some monatomic gold to the water.
