Currend dvb api specification doesn't say anything.
An older version of the specification
(http://linuxtv.org/downloads/old/linux_dvb_api-20020304.pdf) says that
the value should be a multiple of 10E-9, so that 2500 means 2.5*10E-6 or
1 error in 400000 bits.
I don't think that many drivers do the scaling, they just report
whatever the card tells them.
