The UHD USRP $sourk.title() Block:
Device Address:
The device address is a delimited string used to locate UHD devices on your system. \\
If left blank, the first UHD device found will be used. \\
Use the device address to specify a specific device or list of devices.
USRP1 Example: serial=12345678
USRP2 Example: addr=192.168.10.2
USRP2 Example: addr0=192.168.10.2, addr1=192.168.10.3
Num Motherboards:
Selects the number of USRP motherboards in this device configuration.
Reference Source:
Where the motherboard should sync its time and clock references.
If source and sink blocks reference the same device,
it is only necessary to set the reference source on one of the blocks.
Subdevice specification:
Each motherboard should have its own subdevice specification \\
and all subdevice specifications should be the same length. \\
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). \\
If left blank, the UHD will try to select the first subdevice on your system. \\
See the application notes for further details.
Single channel example: :AB
Dual channel example: :A :B
Num Channels:
Selects the total number of channels in this multi-USRP configuration.
Ex: 4 motherboards with 2 channels per board = 8 channels total
Sample rate:
The sample rate is the number of samples per second input by this block. \\
The UHD device driver will try its best to match the requested sample rate. \\
If the requested rate is not possible, the UHD block will print an error at runtime.
Center frequency:
The center frequency is the overall frequency of the RF chain. \\
For greater control of how the UHD tunes elements in the RF chain, \\
pass a tune_request object rather than a simple target frequency.
Tuning with an LO offset example: uhd.tune_request(freq, lo_off)
Antenna:
For subdevices with only one antenna, this may be left blank. \\
Otherwise, the user should specify one of the possible antenna choices. \\
See the daughterboard application notes for the possible antenna choices.
Bandwidth:
To use the default bandwidth filter setting, this should be zero. \\
Only certain subdevices have configurable bandwidth filters. \\
See the daughterboard application notes for possible configurations.
