Hi @JColvin, Thank you for your answer. I'll send my questions directly to them, as you suggested. Regarding the SDR, how does it typically work? Is it a PC software that will send the data to the SDR through the USB port? If yes, how does it work to send and receive data? Is a file that is transmitted? Thanks, Jones

Hello, I’m looking for an SDR radio for an application and have a technical question regarding the Ettus USRP 210 product. I will explain before my application, and then I will ask. I never worked with an SDR board. Our application will generate data through a PRBS generator with a TTL or ECL logic level. Maybe it will have a TTL/RS422 converter. Then, the data will be sent to the SDR to be modulated and transmitted in a loopback channel. The received RF signal will then be demodulated, and a BER tester will analyze the digital output. Thus, is the GPIO connection of this board possible to use as data input/output? If yes, what is the logic level of the GPIO port? Is there another option if this board does not support this operation? Our bit rate is not high. It is in the order of 1 Mbps. If the GPIO is not used for data input/output, could I use an RS422/USB converter to send the data directly to the USB port in a full duplex condition? Thanks
