H-Field Probe Usage

I have the chipwhispere lite 2 part board, the probe set with power supply and the breakout board. I’m trying to use the h-field probe on an ARM Cortex A15 but cant get any readings at all from it. I have it connected to the LNA and the LNA to the power supply, The scope is connected per the software, there isn’t any tutorials I have found on using the h-field probe or going after external boards etc… can you provide some information?
