hi all,
I have made a simple program for sine transmission which is just a
replicca of usrp_siggen. Im successful in transmitting a sine wave
with the help of side A of usrp1, but when i want to transmit it by
side B, it doesnt give any error but it doesnt transmit either...
My code is given as:
from gnuradio import gr, usrp
class my_top_block(gr.top_block):
def __init__(self):
gr.top_block.__init__(self)
self.u = usrp.sink_c()
#self.pick_subdev = usrp.pick_tx_subdevice(self.u)
self.pick_subdev = (1, 0)
########### here the code works fine if i pick side A in that
case self.pick_subdev=(0,0), but when i select side B as given in the
code, it doesnt work
print self.pick_subdev
self.subdev = usrp.selected_subdev(self.u, self.pick_subdev)
print self.subdev
r = usrp.tune(self.u, 0, self.subdev, 2450000000)
self.subdev.set_enable(True)
self.siggen1=gr.sig_source_c(1000000, gr.GR_COS_WAVE, 10000, 16000)
self.connect(self.siggen1, self.u)
print "Using RX d'board %s" % (self.subdev.side_and_name(),)
self.run()
def main():
tb = my_top_block()
tb.run()
if __name__ == '__main__':
main()
kindly help me on this
Regards,
Ebtisam
