You can control the sensor and get IF signal directly or through included ADC by means of different expansion connectors.  The included DDS modulator can be programmed with a set of different modulation ramps through the SPI link available on the expansion connectors. The IF signal can be obtained directly in analog format or already sampled by the included ADC through the same SPI link used to program the DDS modulator. The following paragraphs give you the pin-out of the different expansion connectors:
