Hi,
sorry for sending the email to both list, but it seems it might be a joint topic. Please advise ma if I'm wrong.
However here is my situation:
I have send identical signals (1MHz sinusoidal) to these two daughter boards and measured the actual output signal with a spectrum analyzer as described is the linked file:
The XCRV gives the DC-leakage at carrier, my signal at carrier + 1 MHz and the image at carrier - 1 MHz. But the SBX only gives a 14 MHz wide something I cannot classify.
Maybe the SBX is broken? Maybe it doesn't work correctly with the USRP1 and Gnuradio?
Any advise is appreciated.
Mario
