It is an easy mistake to make, because dB relative to a microvolt is often
written as dBu rather than
using the Greek letter 'mu'; a limitation of the ASCII character set!!

dB relative to a microvolt is written as dBuV, so there need be no
confusion.


Well I am afraid that RF engineers are a lazy breed and it is often written
as dBu, much in the same way as dBm.
