Interface with USRP E3xx radio hardware


The comm.SDRDevE3xx radio object interfaces with a USRP™ E3xx radio hardware. With this object, you can configure the radio hardware and the host computer for proper communication.

The object supports these radio hardware devices:

  • USRP E310

  • USRP E312


To create a comm.SDRDevE3xx radio object, use the sdrdev function with argument 'E3xx'.

dev = sdrdev('E3xx')

If you configure the radio hardware with an IP address other than the default during the host-radio hardware setup, you can also specify the new IP address when creating the object. Set the IPAddress property upon creation of the object by using a name-value pair.

dev = sdrdev('E3xx','IPAddress','');

Name of E3xx radio hardware, specified as a character vector.

Data Types: string | char

IP address of the radio hardware, specified as a dotted-quad character vector. This value must match the physical IP address of the radio hardware assigned during hardware setup. For more information, see Guided Host-Radio Hardware Setup. If you configure the radio hardware with an IP address other than the default, update the IPAddress accordingly.

For example:

dev = sdrdev('E3xx');
dev.IPAddress = '';

Alternatively, you can specify the IP address when creating the object:

dev = sdrdev('E3xx','IPAddress','');

Make sure your radio hardware is configured for host-radio communication by following the steps in Guided Host-Radio Hardware Setup.

Create a radio object for your radio hardware.

dev = sdrdev('E3xx')
dev = 
  SDRDevE3xx with properties:

     IPAddress: ''
    DeviceName: 'E3xx'

Use this object to get radio hardware information.
