hi community,i wondered how the USRP is transmitting the signal even if i set the transmitting gain to ZERO.
ZERO is 0 dB scale...
and same as the case with receiving section. what does setting gain in USRP sink will do ? and what is this gain referred to? is it just to set the PGA's gain or something different. please help me..
http://files.ettus.com/uhd_docs/manual/html/dboards.htmlAssuming you have the XCVR daughter board and the receiver end. For a given gain setting, e.g, 50 dB, the uhd itself decides and divides the gain between VGA and LNA.
thanks, lingeswar.
