Hello!
I want to use the gr.file_sink function, but if connect to a USRP i became
allways 15,3 MB big file.
But if i connect a sinus source, i became a much more bigger file. ( that's
normal thing)
I want latter see my files with pylab but now, i can't open.
I use the followed code:
class raw_data(gr.top_block):
def __init__(self):
gr.top_block.__init__(self)
usrp_decim = 16
audio_decimation = 10
self.IF_freq = 1e3
self.u = usrp.source_c()
adc_rate = self.u.adc_rate() #" 64 MS/s "
self.demod_rate = adc_rate / usrp_decim #" sampling rate "
self.u.set_decim_rate(usrp_decim)
self.subdev = usrp.selected_subdev(self.u,
pick_subdevice(self.u))
self.u.tune(0, self.subdev,
self.IF_freq)
self.audio_rate = self.demod_rate / audio_decimation #""" 32kHz
"""
self.src = gr.sig_source_c(200, gr.GR_SIN_WAVE, 350, 0.1)
self.fajl = gr.file_sink(gr.sizeof_gr_complex,
"/home/sdr/Desktop/data.txt")
self.connect(self.u, self.fajl)
if __name__ == '__main__':
try:
raw_data().run()
except KeyboardInterrupt:
raw_data().stop()
pass
What did I wrong?
