Spectrum with just TX_EN

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,
