-The OsmoSDR Source Block:
-
-Device Arguments:
-The device address is a delimited string used to locate devices on your system.
-Use the device address to specify a specific device or list of devices.
-If left blank, the first device found will be used.
-
-Frequency:
-The center frequency is the overall frequency of the RF chain.
-
-Frequency correction:
-The frequency correction factor in parts per million (ppm).
-
-Sample rate:
-The sample rate is the number of samples per second output by this block.
-
-Gain:
-Overall RF gain of the device.
-
-Antenna:
-For devices with only one antenna, this may be left blank.
-Otherwise, the user should specify one of the possible antenna choices.
