?Dear All,

For some experiments I would like to transmit using N210s with XCVR2450  
with maximum transmit gain.

I can see Ettus website that the XCVR2450 board in the transmit path has  
a gain of:  
VGA: 0-30 dB range  
BB: 0-5 dB range?

Can I just set the gain via GNU Radio/UHD to 35, or do I need to set  
these two values individually, and if so how.

I read this thread, but didn’t quite follow

Thanks!

You don’t need to address the gain elements individually, unless you  
have special requirements. UHD will distribute the requested gain  
setting  
appropriately.
