Could somebody explain this question???
To whom it may concern:

I have read your website on theoretical calculation and/or proof of
the dBuV vs dBm conversion. My problem is when performing ambient
radiation measurements for EMI under Mil-STD-461 I seem to read roughly
-120dBm when measuring dBms directly and roughly 20 dBuV when measuring
dBuV directly.

The difference factor in the actual measurement is 140 dBs versus the
theoretical 107 dBs. Is there an explanation for this?

Regards,

Brian Garvey
