OMG you see Building 7 in the above clip!  That's proof!   

The movie San Andreas opens tomorrow, perhaps there was confusion...

That 20KHz bandwidth limit won't be measuring too many pulsed circuits accurately...

PW

PW,

I like that word: accurately...

I read a quote sometime back, I can not locate the quote right now unfortunately, but it was something similar to: "The output was significant enough, such that the possible error would be insignificant"

All meters have a degree in measurement error, no matter how expensive!

Thus the +- in the spec sheet.

Measurement Error is inevitable, to try to minimise this degree of error should be the end users objective, with the equipment they have on hand.

What's your +- PW?

Ahem... I am 'lite' on the pop culture these days.   I looked at a trailer and I see the good old Hoover dam blows again.  You could be typing a message into your computer and all of a sudd

I would not try to measure the input/output power in Tinman's circuit, for example, with such a limited bandwidth device.  The frequency content of his waveform's exceed the bandwidth of the Hantek probe.  As TK suggested, the proper use of a low inductance CVR will provide more accurate results.  Even the Allegro device AC mentioned previously rolls off at 120KHz or so, and has a fairly large amount of temp dependent offset.  I believe I read +/-8% or so total error for that device And worse at low current levels over the full temp range).

I see all these low cost DSO's floating around and yet it seems no one ever uses the FFT function to look at the actual frequency content of their waveforms.  Except for pure sine waves, the trigger frequency indicated by a scope has little to do with a waveform's frequency content. 

I like the word "accurately" too...

An inaccurate measurement is not really a "measurement".

PW,

Agreed, but you did not answer my question.

All measurements will still have a degree of In-accuracy! No matter how expensive the equipment! This is unavoidable.
