The NetSDR Option X2 board adds a second coherent channel input to existing NetSDR radios. The Option-X2 includes a high performance 10 MHz reference input VCO that synchronizes both ADCs to the same reference. This option enables the unused BNC connector on the back of the NetSDR as a second RX input. This board includes a high performance 16 bit ADC, filter bank and separate attenuators. In addition, the new FPGA configuration allows phase adjustments in 32 bit precision of each receiver for beam forming applications. The I/Q data can be formatted as separate I/Q streams for each channel or as a sum or difference of both channels after phase and amplitude adjustment.
