The UHD Sink Block:
Args:
Args is a delimited string used to locate UHD devices on your system. \
If left blank, the first UHD device found will be used. \
Used args to specify a specfic device. \
USRP2 Example: addr=192.168.10.2
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.
Antenna:
For subdevices/daughterboards 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.
