Hello,
I am currently trying to recover a signal(sine wave) that goes into my
RX2 path on the Ettus N321/N320. However, I am having trouble
recovering the signal.
My current set up is using a separate signal generator that is fed
into the RX port of the Ettus. I run the example rx_samples_to_file
with the following parameters…
|./rx_samples_to_file --nsamps 3000000 --channel 0 --ant "RX2"
--subdev "A:0" --gain 50 --rate 3e6 --freq 100000|
And my signal generator(asynchronously) is sending a sine wave at 100
Khz. However, I am having some trouble recovering the original signal.
I have also tried collecting samples while the signal generator output
was off, but the samples I recover from IQ appear to be the signal
generated by the internal RX LO, which is strange, since if there is
no input on the RX, the IQ should just a be a string of zeros(plus
some noise). Any feedback is greatly appreciated.
Thanks
Joe
The device doesn't tune below 3MHz.
