In this document:
gnuradio.org/redmine/attachments/129/USRP_Documentation.pdf
It says that the the full range of the ADCs is 2Vpp, and of the DACs, it's 1Vpp. Is this accurate for the NI USRPs, specifically USRP 2921?
Many thanks

Hi Hkhalili,
What is it that you're trying to do with the USRP? In the NI USRP 2921 the ADC and DAC have ranges greater than those you have stated in your post.
Hope this helps,

Hi Charlotte,
I am trying to characterise the front-end (gain). I am inputting a signal using a signal generator and it would be nice if I could assign units (dBm) to the values I read from the USRPs instead of them being arbitrary between -1 and 1.
Many thanks,
Hassan

Hi Hassan,
So you want to know the voltage ranges to perform that conversion from arbitary units to dBm?

Hi Charlotte,
That's exactly right, if possible.
Thank you

Hi Erik,
Are there specs for mapping those I/Q values to dBm values?
