-The UHD Single 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.
-USRP2 Example: addr=192.168.10.2
-USRP1 Example: serial=12345678
-
-Subdevice specification:
-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: A:AB
-Dual channel example: A:AB B:0
-
-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.

+The UHD USRP Sink 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.
+
+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.

+The UHD USRP Source 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.
+
+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.
