Burst detector files

GNU Radio
1

I am working with the uhd_burst_detector examples. I ran it for 0.5
second
(using sleep) and was able to generate files using the internal trigger.
It
generates the correct number of files with the correct time stamps given
the
internal trigger waveform.

I tried to read the file using the read_complex_binary.m file and was
able
to get 1000 data points, but the values were all very small (see the 1st
10
values below). Am I reading them correctly?

1.0e-003 *

-0.0916 - 0.1831i
0.0916
-0.2136 + 0.0610i
-0.1221 + 0.1526i
0 + 0.2136i
-0.0916 + 0.0916i
0.1831 - 0.0610i
0.1526
-0.0916 - 0.2136i
-0.0305 + 0.0305i

Thanks,

Eugene,

That’s actually not a very weak signal. Convert it into dBm and see
what it’s power is.

When working with real signals over the air, you have to get used to
working with small numbers.

I understand, it turns out I misread how the flow graph routed the
vector source. I thought that the internal trigger was flowing in as a
source rather than the RF threshold. Thanks for the help.
