The BasicRx daughterboard is a low-cost daughterboard which can accept RF signals from 1 to 250MHz.
BasicRX
The BasicRX provides a straightforward wideband interface to the USRP's ADC. It is an ideal daughterboard for users who require an external RF front-end or need to inject raw signals into the USRP. The wideband transformer enables operation at frequencies ranging from 1 to 250 MHz on each channel.
Frequency: 1 – 250MHz
The BasicRX is designed for use with external RF frontends as an intermediate frequency (IF) interface. The ADC inputs are directly transformer-coupled to SMA connectors (50Ω impedance) with no mixers, filters, or amplifiers. The BasicRX gives direct access to all of the signals on the daughterboard interface (including 16 bits of high-speed digital I/O, SPI and I2C buses, and the low-speed ADCs).
