Dear Sir/Madam,

I have a question to make about lms6002d. We build a customized RF  
card with lms6002d IC and we connect the RF daughter card through the  
FMC HPC connector with an FPGA. We drive the following signal from the  
FPGA SPI(4 wire mode) DATA (both RX/TX), TX\_EN, RX\_EN, RX/TX\_CLK,  
IQ\_SEL. If we want just to transmit with lms, should we be able to see  
spectrum even without data in the spectrum analyzer in the default  
settings of Lms, just by enabling the TX\_EN signal?

Thank you in advance,  
George
