[Discuss-gnuradio] file sink issues

[Eugene Lee]

I am having an odd problem with the file sink. I am inputting a pulsed signal
into the N210. (~200 ns, 1 us period). The pulse frequency is a 5 MHz above
the center frequency. I am running at 50 MSps with a RFX2400. I can see the
correct plot when using the FFT sink and the scope sink.  I see a short
burst of sinusoidal signal and 800 ns of zero. 

However when I use a file sink, I see a 1.5 MHz signal that pervades the
entire stream. I have recorded a signal before without a problem, but not at
50 MSps.

If I look at the abs value, then it appears as if I have a DC offset.

But I am not sure why I only see this problem when I stream to a file as
opposed to the file sink.
