LMX8410LEVM: EVM doesn't work what expected

Part Number: LMX8410LEVM


We are trying to evaluate LMX8410LEVM and checked LO_P and IF_IM output but the result was not expected.

LO_P power was -50dBm as attached and there is no IF_IM signal(20MHz). Is -50dBm power of LO_P right result?

I guess not to be able to configure TISCpro properly. Would you review TICSpro setting? If the configuration is no issue, what is thinkable reason?

VCC = 5.3V.  LO frequency sets 7.98GHz. RF frequency applied 8GHz, 3dBm power.
