Dear Anders,
sorry for the late reply!
We would like to know what the dynamic range of the DAC is, so that we can
determine a maximum difference in power between several different signals.
So, technically, the 12 bit DAC would make ca 12·3 dB dynamic range.
But: the device is typically used in an oversampling scenario, so you
can add more dB. Hence, this is impossible to say without knowing your
sampling rate and Master Clock Rate in use.
Even so, dithering can make a great difference! So, this even further
depends on the nature of your signals. Can you elaborate on what you're
building?
Best regards,
Marcus
If you're talking power levels, then it's number-of-bits X 6.02dB,
since power is proportional to the square of the voltage (for a fixed
impedance).

Hello USRP mailing list
We are trying to add baseband signals with varying signal power on a PC and
then transmitting the combined signal using a B210 board.
We would like to know what the dynamic range of the DAC is, so that we can
determine a maximum difference in power between several different signals.
We have so far been unable to find any information about this, so any help as
to what it is or where we can find more info is greatly appreciated!
