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...
If you need the widest bandwidth and frequencies up to 7.2 GHz, the NI Ettus USRP X410 may be the best fit. There are many options available in between these two examples. Figure 15 below gives a full break down across all models. Figure 4: USRP 2901 and USRP B200mini Low SWaP-C ...
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...
