Second Coherent Channel Option for NetSDR

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 (IF/RF2) 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. The X2 option can also be configured with trigger input. This allows multiple dual NetSDRs to be synchronized. When used with SpectraVue or CuteSDR software, only one channel is supported. In X2 mode the maximum output sample rate is limited to 1 MHz. The radio can still be used as a single radio with 2 MHz max sample rate.

Possible uses:

Polarization control

Beam steering

Radio Astronomy Interferometers

Direction Finding

Noise Antenna subtraction

Dual band simultaneous reception and recording

Our products are proudly designed, manufactured and assembled in the USA.


** No dual channel software is supplied. Dual channel support is only via GNURadio, GRC or custom applications using the NetSDR protocol.
