SMA connector J5. Connect positive quadrature signal to SMA connector J4 and negative quadrature
signal to SMA connector J3.
3. Connect a mini-USB cable from the computer to J8. This should turn ON the blue LED (D3).
4. Terminate any unused SMA connectors to 50-Ω load.
5. Connect 6-V power adaptor. This should turn ON the red LED (D1).
6. Launch the TRF3722 GUI.
