Need help in lms7002m external loopback via the SMA connectors

1

Hello
I’m using lms7002m evb and I want to do an external loopback via the SMA connectors
and the mode is
SDR not DDR
SISO not MIMO
can you please help me with a configuration file to do that

Thanks

Connect TX2_A to LNAL_A.
TX and RX LO are set to share TX PLL 800 MHz.
Not to overload receiver you need:

  1. lower transmitter gain - “TX pad gain control” and “Frontend gain”.
  2. and also set lower receiver gains - “LNA gain”, “TIA gain”, “PGA gain”.
    TxTSP generates 5MHz test signal - enable CMIX, insert 5 MHz in NCO table, Upload NCO, select “Test signal” and “DC source”.
    Run Calibrations, adjust calibration settings manually - you will see how DC and image are disappearing.
    If you open FFT viewer, you should get something like in this screenshot:

    If you give me your email, I will send you configuration file.
