Connect two daughterboards with a coax cable

Hi,

I 'd like to connect two daughterboards (on two separate USRP boxes)
with a coax cable. The cable will replace the two RFX2400 antenna.

What kind of coax cable do I need to buy? Anyone has any experience?

Thanks.

I don’t have experience in that but you need a 50R coax cable and
don’t forget to put an attenuator, i.e. 50dB.

You should NOT connect the two daughterboards together like that, or you
will destroy them. You would need at least 50dB of attenuation between
them.

Dear sir,

We have USRP - RFX900 systems in our laboratory. I am trying to connect
the “RF out” of the transmitter to the “RF in” of the receiver using an
RF Cable with attenuators.
I have with me 6610.19.AA - HUBER + SUHNER 10dB/2W 18GHz attenuators,
about 4 of them.
I wanted to know if it is alright for me to use these with the systems.
Is there any specific attenuator that you recommend for the USRP system?
Is there any document describing the usage of such attenuators with the
USRP boards?

thanks again
regards,
Shobha
