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:
https://dl.dropboxusercontent.com/u/54059714/2013JUL22_Eval_USRP1_XCVR2450_SBX_pub.pdf
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
