[Discuss-gnuradio] puzzle of multi_fft.py

[Ling Huang]

Hi,
I modified multi_fft.py to work with Rfx400 and Rfx2400. It seem to work.
But when I tried to generate signal from another USRP, I got confused. First
I set a 400MHz signal generated, the multi_fft work well and show the power
is up to 40dB(Input 0 record address@hidden). Second I set a 2400MHz signal
generated, the power show up does not change at all(Input 1 record
address@hidden). Then I try to run usrp_fft.py to test it, it does show the
signal is generating.
What's wrong with  my code? Or the usrp just is not able to work fine with
two rfx daughterboard？

Can anybody help? 

here is the image of the multifft result and my code.
