Verifying the Operation of the USRP Using UHD and GNU Radio | This AN explains how to use UHD and GNU Radio, once installed, to verify the correct operation of the USRP. Several test procedures are explained in detail. Several tests make use of an optional spectrum analyzer and signal generator. | |

Implementation of a Simple FM Receiver in GNU Radio | This AN shows a quick and simple implementation of an FM receiver for the USRP using GNU Radio. The goal is to easily demonstrate a practical application, and to verify that the USRP is functioning properly. | |

Interrogating Passive Wireless SAW Sensors with the USRP | Typical interrogator design for wireless SAW sensor systems require many discrete components and lengthy build times, making it difficult to rapidly adapt to sensor designs in a research environment. We have employed the USRP B200 as a SAW sensor interrogation system. Interrogation of wideband orthogonal frequency coded (OFC) SAW sensors imposes strict requirements on the timing and synchronization of the transceiver. The USRP FPGA has been modified to operate in a synchronous, pulsed mode of operation, allowing rapid data acquisition and the full 56MHz bandwidth to be utilized. Data from the USRP is passed to a custom matched filter correlator routine to extract sensor parameters. The system is capable of interrogating multiple sensors, simultaneously. Demonstration of the system is accomplished by wirelessly interrogating SAW sensors at 915MHz and extracting temperature. | |

Experiments with the UBX Daughterboard in the HF Band | We show the results of experiments with the UBX daughtercard on an USRP X310 platform for use in the HF frequency range, from 1.8MHz to 30MHz. While the UBX is nominally rated for use only down to 10 MHz, with careful flow-graph design, and pre-filtering, it provides quite-good performance across the HF bands. | |

Implementation of an ADS-B Receiver in GNU Radio | This AN guides the reader through the implementation of an ADS-B receiver using the gr-air-modes Out-of-Tree (OOT) module for GNU Radio. An explanation of ADS-B is also provided, and several real-world, over-the-air examples and profiled. | |
