Hi Marcus,
Thank you for the prompt reply. I have attached the two python programs
that have been written to do this type of acquisition. From Snafoo.py the
only section of importance is the Rupdate. Before any file is written, the
program checks the hard drive to make sure there is enough space to complete
the file. If there is enough space, then the program initiates the data
collection program (rx.py). The inputs to this class include the directory
to save to (self.indir), FIR filter coefficients (self.fr), and the file
size in seconds (self.fs). Then the method 'run' is executed, which is a
function from the gr.top_block class.
After writing this, it seems like the problem can potentially be the
commands that are executed between files. These command will take a brief
amount of time, but enough to cause a slight phase difference between files.
Do you think this may be the cause as well? If so, do you possibly have a
solution?
Thanks,
Robert
