i want to save some output from the usrp and watch it with octave.
The usrp.source_c(...) block generates IQ data as pairs of 32-bit
floating point values.
Or to avoid any confustion about how many samples are getting
generated, I think it's easier to think that it generates samples that
are of type std::complex<float>.

Yes its confusing me. :-(
Ok, here is a clipping from the data at the beginning:
0 + 0i
0 + 0i
-1 + 0i
0 - 1i
-13 + 2i
65 - 32i
-183 + 98i
412 - 233i
-831 + 478i
1572 - 918i
-3050 + 1745i
8314 - 4139i
-12548 - 5491i
3899 + 10329i
3523 - 2748i
-1791 + 1379i
951 - 738i
-484 + 378i
219 - 176i
-84 + 69i

How can i collect bits from the I or Q Signal ?
So the first 16 bits from the left side are the I Signal ?
And the first 16 bits from the right side are the Q Signal ?
Where is the beginning of the samples ?
Maybe the curious values at the beginning is the
start point ?
