Help!
Today, I connect two flex2400 directly through a coaxial wire. Maybe
the gain is too high, the receiving one don't work any more.
One I plug the broken one on the mother board, the python graph seems
not running and no data is transferred from usrp to PC. I see nothing
on the fft window of usrp_fft.py.
I wonder which part of the daughter borad is broken and if it could
be repaired.
I hope Ettus Research can provide me some repair service and it's
free cause the board is just bought about 5 months ago ;)
Hanwen,
I don't understand why you think this should be a free repair.
Everything you purchased from me worked at the time you received it,
and has continued to work for 5 months. The only reason it no longer
works is that you did something which:
1) I have repeatedly stated should not be done.
2) Would have destroyed just about any receiver you are likely to
find.
Just to be clear for everyone out there -- if the products you buy
from me don't work WHEN THEY ARRIVE, I will replace them. If you
break them, I am not responsible. This includes, but is not limited to:
Lightning strikes to your equipment
You dropping metal objects onto powered circuit boards
Spilling your coffee on them
Transmitting directly into the receive port
Not taking adequate static safety precautions
Using power supplies other than the ones I provide
Please also note that it is EXTREMELY rare for items to arrive
broken, since everything is tested immediately before shipment.
Matt
