Sorry, but even when it might appear that way, that issue isn't simply a programming error. Repair of the FFT would be relatively easy, but could affect other math and measurement functions in a negative way - and the perfect solution might take a lot of additional resources. So the viable solutions are still discussed internally and I cannot even know how much effort the final (safe) solution will be.

A "Measurement Track" (section 18.5 of the manual) should do what you want: Calculates time-dependent measurements within one capture and plots them like a trace.

Thanks.

Thats kinda nice, but why didnt they include this in the math? Alignment is everything with a scope.  :palm:

2 Sentences in the manual, but 6 settings / buttons in the scope.

No need to be sarcastic.

I thought it was clear that I was talking about oscilloscopes and not power meters, which commonly have an order of magnitude better accuracy. Consequently, I would also prefer a VSWR of 1.05 for the power meter.

I thought it was clear that I was talking about oscilloscopes and not complete measurement setups. Nowhere did I state that a better VSWR could not be beneficial at times, and that it could not be achieved by adding an inline attenuator – even though in practice I’ve more often wanted to improve the output impedance match of a generator than the input match of an oscilloscope – but that’s just me.

joeqsmith:
There is no reason an oscilloscope could not measure power.  In this thread we are seeing a lot more applications and I don't see this curbing anytime soon.  I'm not suggesting  an oscilloscope is a replacement for a power meter, network analyzer, spectrum analyzer....   Rather, modern scopes are slowly smearing the lines.   As their performance improves and the features they support grow, I suspect such details will become more important.   While a VSWR of 1.5 may be a good guideline when talking about antennas, it's not something I have ever considered when making a measurement in the lab.  Certainly not a standard.   Rather, I treat each measurement as a unique problem.

Oh well, sounds like I have my answer and not trying to upset you.  Thanks for the input.

Outstanding demos and pdf documentation, thank you.

You may want to add in the opening post a link to the second pdf, too ( https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/msg5422826/#msg5422826 ).  The second pdf has only half the number of downloads than the first, would be a pity for the second part to remain lost somewhere inside the thread.
