Not that I have any real need to know but I am just curious what the "m" abbreviation stands for in the raw data example of "644m + 53.2m"? Does it happen to represent milliVolts RMS, milliVolts PTP calculated from the ADC output >measurement values or possibly something else?
m - milli
u - micro
M - mega
G - giga
And so on
Re Im value - just complex number
644m + 53.2mj = 0.644 + 0.0532j
