Using a resistor to messure power consumption of a circuit.

It would be a lot easier if you could post CSV files.  Otherwise, I will have to extract the values which is possible, but somewhat time consuming.

What are CSV file's Mark?

Comma separated variables.  It is a common format that most digital scopes can export, and any spreadsheet can import.

To keep it simple and almost precise - I would simply add a driver stage - and measure the DC power consumption of the driver-stage.

With a modern scope you can get the power directly using math function by measuring voltage on DUT and voltage on current sensing resistor.....
__BUT__ a scope is not a precise instrument - and you multiply the errors in that case - and if you derive the power from a single period - this error is multiplied by 172.000 within a second for 172kHz.
... and you can export the data using csv or whatever
- but believe me - thats lots of effort - and will never reach the precision you got with 2 cheap meters measuring DC amps and DC voltage.
rgds.

Some people are of the mind that a decoupling filter spoils whatever magic they think might be going on inside their circuits.  When they see that DMMs don't show OU, and neither do their scopes on the DC side they figure the problem is the filter and not their circuit.  Former prof. Steven Jones claimed 8X overunity for awhile with a Joule Thief derivative.  His results were all measurement error that the kind of filter you propose would instantly expose.
