RFX2400, really noisy signal

Has anyone achieved a good received signal with RFX2400? When I worked
without it , I had signals that went form 4000 to -4000. Now I’m using
the deinterleave and the received signal is really noisy when I see it
with the scope, and can’t achieve up to -40 to 40 amplitude in the
scope. How’s that?
I’d really appreciate any kind of help 'cause I can’t understand
what’s happening


src = usrp.source_c(0, usrp_decim, fpga_filename=“std_2rxhb_2tx.rbf”)
src.set_mux(gru.hexint(0x32103210))
src.set_nchannels(2)
subdev_spec1 = (0,0)
subdev_spec2 = (1,0)
subdev1 = usrp.selected_subdev(src, subdev_spec1)
subdev2 = usrp.selected_subdev(src, subdev_spec2)
subdev1.set_auto_tr(True)
subdev2.set_auto_tr(True)
subdev1.select_rx_antenna(‘RX2’)
subdev2.select_rx_antenna(‘RX2’)
r=src.tune(0,subdev1,freq)
r=src.tune(1,subdev2,freq)

self.scope_1=scopesink.scope_sink_c(self,panel,’’,sample_rate)
self.scope_2=scopesink.scope_sink_c(self,panel,’’,sample_rate)

di=gr.deinterleave(gr.sizeof_gr_complex)
fg = gr.flow_graph ()

self.connect (src,di)
self.connect ((di,0),self.scope_1)
self.connect ((di,1),self.scope_2)

You need to control the gain
