The PLL controls the VCO so that the device clocks and LO can be frequency-locked to a reference signal. The transmit amplifier amplifies the signal and transmits the signal through the antenna. 该信息是否对您有帮助? 否 向前 USRP-2950 40 MHz Block Diagram 向后 没有下一部分...
Additionally, some Ettus Research branded USRP models and configurations may not be supported; see Figure 16. Figure 12: LabVIEW Block Diagram with the NI-USRP Driver API Programming with Open-Source Workflows: USRP Hardware Driver (UHD) and GNU Radio Many SDR users prefer to program USRP ...
The LabVIEW block diagram for the 2x2QAMAlamouti VI is organized into three sections. The upper left section of code synthesizes a signal for transmission. The code in the middle lower portion of the diagram initiates the Tx/Rx operations with the NI USRP hardware. The upper right section of...
Signals received by the USRP-2932 are amplified, downconverted, filtered, digitized, and decimated before being passed to the host computer. Signals transmitted by the USRP-2932 are upsampled, reconstructed, filtered, upconverted, and amplified before being transmitted. Note The RF switch allows tran...
