| 9 | | Wiserd producer module ''signal_from_file'' can be used for transmission of a custom signal. The signal needs to be saved in a binary file, containing 32bit float values of I and Q samples of the signal. To use wiserd on a USRP X310 equipped node (e.g. node3-1 on grid.orbit-lab.org), we can use the ''wiserd-x310.ndz'' image, which has the latest version of wised preinstalled in the root directory. After running wiserd, we can use the following commands in order to set the required parameters (in this case we assume the central transmission frequency of 700 MHz, signal bandwidth of 200 MHz, transmitter gain of 20 dB and our signal is stored in the ''signal.bin'' file): |

After the node is imaged and accessed, we need to make an additional adjustment in order to work with USRP X310 by running ''ifconfig eth2 mtu 9000'' on the node (note that this should not be done on nodes with USRP 2 or N210).
