dBuV is a logarithmic-relative measure defined as follows:






     dBuV = 10*log10( x uV / 1 uV)
          where x is the voltage in microvolts.

This relationship yields:
     1 uV => 0 dBuV
     2 uV => 3 dBuV
    10 uV => 10 dBuV
   100 uV => 20 dBuV

dBuV is a nice shorthand way of describing wide dynamic range measurments.
