I think i know the answer to this question but I still hope i am not
Setup N210 with SBX
One of my colleagues plugged in TX/RX an external discone antenna with
RG58 cable playing around in the 3 Ghz band. Somehow he managed to get
to 400 Mhz where db increases partly because of the antenna gain and the
reduced attenuation of the cable. After some experimentation the SBX
receiving signals. I changed antenas (LP0965) cables etc removed and
reinstalled the SBX but it wont give me any signals. Usrp appears to
alright - leds flashing etc but i dont have another daughterboard to
SBX is flashing as well but no signal in TX/RX nor RX2. When tuning
different frequencies there are no errors etc, but i receive just noise.
think that the down left corner of the SBX (as you see it- to the left
RX2) is getting hotter than it used to.
That leads to the question, is the Db dead? Any way to fix it? Is there
limit in the input db when connecting an external antenna? I would guess
attenuator would be needed?
