Uhd subdev spec. clear_command_time (self, size_t mboard = 0) ¶ Clear the command time so future commands are sent ASAP. C-level interface for working with an RX streamer. Jul 9, 2025 · These values can be used for uhd::usrp::multi_usrp::set_rx_subdev_spec () and uhd::usrp::multi_usrp::set_tx_subdev_spec () as with other USRPs. uhd. For such a configuration, you set a subdev spec string for every device individually. Note that a subdev spec string always only pertains to a single USRP, even if multiple USRPs are configured to run together. See Streaming Arguments (Stream Args) and Transport Notes for more details. Specifying the Subdevice A subdevice specification (or "subdev spec") string for USRP family devices is composed of: <motherboard slot name>:<daughterboard frontend name> Ex: The subdev spec markup string to select a WBX on Sep 26, 2023 · Mbx Subdev Spec Each motherboard should have its own subdevice specification and all subdevice specifications should be the same length. active_thread_priority (self) → int ¶ usrp_sink_sptr. A C-level interface for working with a list of subdevice specifications. NOTE: Using a handle before passing it into uhd_subdev_spec_make () will result in undefined behavior. Rear Panel Status LEDs Hi Ben, You will need to specify "A:AB" for the subdev. With multiple devices, the first stream command in a chain of commands should have a time spec in the near future and stream_now = false; to ensure that the packets can be aligned by their time specs. The markup-string is a whitespace separated list of dboard:subdev pairs. The RFX Series boards have independent receive and transmit LO's and synthesizers allowing full-duplex operation on different transmit and receive frequencies. In the current example, assume all the X310 USRPs are using their standard configuration, and all have two daughterboards inside. If you are using GRC, you can simply put the data through a "Complex to Float" block to separate it. usrp_sink_sptr The IF can be adjusted through lo_offset in uhd::tune_request_t. See uhd::usrp::subdev_spec_t for more details. Jul 29, 2017 · So if I call uhd_usrp_set_rx_subdev_spec and then uhd_usrp_set_tx_subdev_spec with A:0 as the subdevice, am I getting RX on channel 0 and TX on channel 1, or am I getting both on channel 0? Jan 8, 2013 · Set the RX subdevice specification: The subdev spec maps a physical part of a daughter-board to a channel number. We will discuss transmitting and receiving on the USRP in Python, and dive into USRP-specific topics including stream arguments, subdevices, channels, 10 MHz and PPS synchronization. Contribute to EttusResearch/uhd development by creating an account on GitHub. USRP in Python ¶ In this chapter we learn how to use the UHD Python API to control and receive/transmit signals with a USRP which is a series of SDRs made by Ettus Research (now part of NI). real*cos (t*w_c) + imag*sin (t*w_c)? where w_c is the carrier and t is time. Set the subdev spec before calling into any methods with a channel number. The subdevice specification can be represented as a markup-string. uhd ¶ Provides source and sink blocks to interface with the UHD library. See uhd::rx_streamer for more details. For more details on selecting the Sub Device, see the Specifying the Subdevice section of the UHD Manual. It will take post-processing to separate the data for each channel. The data will come out mixed in a single stream where the I part of the complex values will be one channel and th Q part will be the other. Best regards, Michael E. Aug 10, 2017 · The subdev spec must be the same size across all motherboards. Jan 8, 2017 · The number and order of channels per device depends on the subdev spec (see also Specifying the Subdevice). Select the subdevice or subdevices for each channel using a markup string. The markup string consists of a list of dboard_slot:subdev_name pairs (one pair per channel). Typically, the user will pass a RX or TX subdevice specification into the API, and the implementation will infer the channel configuration from the specification. 6. usrp_sink (*args, **kwargs) ¶ usrp_sink_sptr. Detailed Description A subdevice specification (daughterboard slot, subdevice) name pairing. Help Usage: uhd-tx [OPTION] Allowed options:. The USRP™ Hardware Driver Repository. Type signature: (raw-> [raw]) The uhd-tx node is for using a device supported by the libuhd USRP hardware driver library. gnuradio. In addition, many of the streaming-related options can be set per-device at configuration time. How many antennas are output for A:A and for A:AB? channel of the DUC is connected. Used to send and receive data between the Ettus Research, LLC product line. Using this node, a raw stream can be transmitted.
