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.
