I bought this board and it seems to be working, However I don know what to do with the CS and PGA pins. Does anyone has a circuit description/schematic?

Farley CS is the chip select for serial programming the MCP4101 digital pot. Tie it to Vcc. The pot initiates to half scale at power on. PGA is the 50R output of the Programmable Gain Amp and is in parallel withe SMA coonector.
