Hi,
I am using the usrp_siggen.py program to transmit a
complex signal to the USRP. The interpolator on the
transmit side generates an I and Q part for my signal
and I transmit it via DAC0 and DAC1.
1)Is DAC0/DAC1 connected to J48/J49?
Now I connect J48 to J19 and J49 to J18.
2)Is ADC0/ADC1 connected to J19/J18?
I give a mux setting of 0x33333300 This I assume
connects ADC0 to the I input of DDC0 and ADC1 to Q
input of DDC0. Now when I see the received signal
using the usrp_oscope.py program, I see 2 signals.
3)Shouldnt I be seeing only 1 signal,the original
complex signal?
I assume what I now see is the real and imaginary part
of the original signal.
4)Why is this so?
Regards
Sudhindra
