The BasicRX/BasicTX daughterboards are low-cost daughterboards that provides direct access to the ADC inputs. The boards can accept real-mode signals from 1 to 250 MHz. The BasicRX/BasicTX is ideal for applications using an external front end providing relatively clean signals within operable bandwidth. Wideband transformers couple each RF input to a single channel of the USRP device's ADC.  The signals sampled by the ADC are manipulated in the FPGA, and the outputs can be processed independently, or as a single I/Q pair. The BasicTX/BasicRX daughterboards are supported by the USRP Hardware Driver™ (UHD) software API for seamless integration into existing applications.

Device Overview

The BasicRX/BasicTX daughterboards are low-cost daughterboards that provides direct access to the ADC inputs. The boards can accept real-mode signals from 1 to 250 MHz. The BasicRX/BasicTX is ideal for applications using an external front end providing relatively clean signals within operable bandwidth. Wideband transformers couple each RF input to a single channel of the USRP device's ADC. The signals sampled by the ADC are manipulated in the FPGA, and the outputs can be processed independently, or as a single I/Q pair. The BasicTX/BasicRX daughterboards are supported by the USRP Hardware Driver™ (UHD) software API for seamless integration into existing applications.
