I don't know how an oscilloscope saves a csv data to the usb stick, so i have to guess. They mostly open the csv file in excel, so no one even knows how its written, no one opens it with a text editor, though it's a text file. The thing i may be missing, are the numbers there in quotation marks, or not. Of course it can be opened in excel, then a column copied to Trinket, though i feel it's like a kind of banal way. In any case the first two rows are likely header, and must just be omitted.

As i have seen, it's time in seconds and voltage in volts, both float numbers in the exponent form. I don't know why so, i think the time column can just be ignored, as the samples are all after regular intervals, check it, but it's almost certain. All that is necessary for the list, is the second column.

There should be only two ways how csv can be written, without quotation marks and with quotation marks. The following are the trinkets to extract the second column in both ways.

https://trinket.io/python/fbf69fdd0e

https://trinket.io/python/85ad4a832f

Then when the voltage is already in volts, there is no need to divide by 50, or whatever number of units in a scale. Because the unit already is volts. And write the y scale just 1. The x scale, when the time column is omitted, should then be the time interval between samples in us. The samples there are float as well, otherwise scale is float, and only multiplying by float makes it float.

Yes all the calculations can be done in excel the same way as in Python, you see how, and there may be a precision problem as i said. Oh well, the lame excel, but do it if you want it so. I still consider the standard to explain things, is Python. One can make a mistake in Python, where all variables are named, it is difficult to make it faultless in python, but then what about excel with its totally not intuitive a3, b4 stuff.

Tell me excel, or maybe tell me matlab. And then you effectively do it so that i cannot say anything at all. Because in what should i talk then, excel or matlab or python? I don't understand why in hell they recommend to open these csv files in excel, people for whom precision should be so important. Excel is not proper for that purpose at all.

Paste your csv file somewhere? It's a text file as i said. Or paste it into a Trinket input.txt, and post the trinket here :) Then i can write a script to extract data from it in an instant.

And how you likely did guess, i should post these two trinkets here, yet again. Why in hell i had to convert the input to int, there was no need to, all works the same when it's converted to float.

Trinket for the input part.

Trinket for the output part.

It is easy to convert CSV, if that really is a problem. No need for spreadsheet, no need for excel. I did write a Python script as you may guess, but if you don't feel like doing it. Like the following web page, choose output options, then choose only one column, and you got it. This is only one of many such online converters. Not to talk about other tools, there are a great number that can do it, CSV is so common format. It's also so terribly simple. I don't understand finding ways to go around, instead of straightforward taking CSV out of oscilloscope and directly doing calculations. It is there and it's a great thing, so why not use it.

http://www.convertcsv.com/csv-to-csv.htm

Otherwise, what do you prefer to use for calculations? Like spreadsheets, they are not precise enough as i did show earlier, excel is also not really free. Only spreadsheet calculator i found was precise enough, but i cannot provide it online anywhere, may be too minimal for you as well.

How are you going to do calculations from the oscilloscope traces?

What else can i say. In Python something is float when it is assigned a float value, that is like 0.0 instead of 0. Any expression where at least one variable or value is float, is also float. while (True): is followed by colon, it just has to by syntax. Otherwise all the statements that follow, have tab before them (indent). It is a tab that is converted to two spaces when you copy code from there, any number of spaces work instead, but there always has to be the same number. The statements that are in such way indented, are in the loop, loop ends with a statement that is less indented, and that statement is already out of the loop. Going through the loop one time, is called iteration.

You don't need to know all Python, only a small subset of it, for almost all electronics calculations that you may need to do. This small subset is almost all that one needs to know to understand these small trinkets above. Is it really so absolutely impossible to learn.

The latest scripts for input and output parts posted here again, for eternity. These are exactly the same as in the trinkets above, just posted here in case if trinkets disappear in some mysterious ways, or such.

Thank you for all your attention.

Now say you get CSV from the oscilloscope, where samples (points) are already in volts, the scripts for input and output parts would be like this.

Quote
#Time between samples in ns
XU = 20.0
#Voltages are in mV
YU1 = YU2 = 1000.0
#Resistor resistance in ohms
R = 47.0
#Frequency in Hz
F = 1000.0

e = 0.0
f1 = open("input1.txt")
f2 = open("input2.txt")
while (True):
  s1 = f1.readline()
  s2 = f2.readline()
  if (len(s1) < 2 or len(s2) < 2): break
  vs = float(s1) * YU1
  vr = float(s2) * YU2
  vl = vs - vr
  pl = vl * vr / R / 1000
  e += pl
f1.close()
f2.close()
e *= XU / 1000000
print("Input power was %.4f uW" % (F * e))
