Dear Marcus, At the receiver USRP, does the SBX daughtercard have any mechanism of phase-lock-loop (PLL) ? I guess the daughtercard should have it because PLL is essential for quadrature downconversion. Please advise, thanks. Regards, activecat On Sat, Jan 11, 2014 at 1:19 PM, Marcus Leech

Dear Sir, I run this command with SBX daughterboard on N210: /usr/local/lib/uhd/examples/tx_waveforms --freq 500e6 --wave-type SINE --wave-freq 5e3 --rate 10e6 What is performed at the SBX, does it multiply (Frequency Modulation) the 5kHz SINE wave with the 500MHz carrier frequency ..?
