I want to generate about 1000 sines in the 50 MHz band. But I am faced
with a situation where USRP does not have output power. I generate an
array of zeros and set the non-zero values at the right frequencies.
I do the reverse fft and send it to USRP.
So, like OFDM?
The maximum output power for daughtercards that are compatible with N210
is about +20dBm. You haven't mentioned which daughtercard you're using.
So, if you're operating at 50MHz bandwidth, that's not a lot of power
for each of your 1000 spectral bins. Also, at 50Msps, you can *ONLY*
use 8-bit samples
over the wire, since 1GiGe can only support 50e6 x (8+8) bits/second.

Hi Marcus
Tell me please, what type of data does USRP N210 sign or
unsigned? And what type of data is better to transfer to a
motherboard for stable generation of polyharmonics
Data "over the wire" from the N210 can be either signed 16-bit or
signed 8-bit complex values (I and Q).
I'm not sure what you mean by the second half of your question,
and perhaps you can elucidate further?
