  • BasicTX Daughterboard 1-250 MHz Tx

    782751-01 | BasicTX USRP Daughterboard (1 – 250 MHz) $ 167.00 USD

    The BasicTX daughterboard provides a simple, wideband interface to the DAC output(s) of a USRP. The BasicTX is an ideal daughterboard for users who want to use an external RF front end, or experiment with the raw signals provided by the USRP. A wideband transformer allows operation from 1 to 250 MHz on each channel.

    Overview

    The BasicTx daughterboard is a low-cost daughter board that provides transmission capability from the USRP from 1 to 250 MHz. The BasicTx uses two wideband transformers to match the dual DAC outputs of a USRP to 50-ohm SMA connections.

    The wide bandwidth of the BasicTx board allows the USRP to operate in a subsampling mode when the desired output frequency is beyond the sampling clock rate of the USRP DACs. Each output of the BasicTx can be operated independently, or combined into a single I/Q pair. Note that appropriate filtering should be utilized in subsampling modes.

    Example applications include transmitters with external RF front ends direct generation of baseband of passband signals and custom daughtercard development

  • BasicRX Daughterboard 1-250 MHz Rx

    782750-01 | BasicRX USRP Daughterboard (1 – 250 MHz) $ 167.00 USD

    The BasicRX provides a simple, wideband interface to ADC of a USRP. The BasicRX is an ideal daughterboard for users who need an external RF front end, or to inject raw signals into the USRP. A wideband transformer allows operation from 1 to 250 MHz on each channel.

    Overview

    The BasicRx daughterboard is a low-cost daughterboard that provides direct access to the ADC inputs.  The board can accept real-mode signals from 1 to 250 MHz. The BasicRx 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 can be processed as two real-mode signals, or a single I-Q pair. 

    The BasicRX does not include a local oscillator or downconverter.

    It is possible to use subsampling methods to receive higher frequencies.  In this case, the user must ensure the signal is filtered to avoid aliasing of undesired signals.
