Keep in mind, these are all RELATIVE measurements not ABSOLUTE.
Indeed. I suggest not using the unit dBm, as that is decibels relative to 1 milliwatt. This is an absolute unit.
It is common to refer to some other standard when comparing relative power, such as dbFS (decibels relative to full scale, usually a negative number) for an ADC.
Perhaps dBANF might work, which would be dB relative to Agreed Noise Floor. I don't think I'd use "dBNF", as that might be confused with Noise Figure in dB.
