Hello Wahhab Albazrqaoe, It is certainly possible to configure each USRP to be tuned to a different frequency and to be synchronized closely in time. A 1 Gigabit Ethernet connection can carry approximately 25 MS/s of 16 bit samples and 50 MS/s of 8 bit samples. We do not support sending 4 bit samples so it is not possible to carry 100 MHz worth of spectrum over the 1 GigE cable of an N2x0 or USRP2. You should operate in Dual Ethernet mode using the MIMO cable to share clock and time references. If you already have external 10 MHz and 1 PPS references that you can send to both then the MIMO cable gives you little benefit in this situation. http://files.ettus.com/manual/page_usrp2.html#usrp2_mimocable
You will be limited to 8 bit samples so you should check that you application will be ok with that limitation. Newer USRPs use faster connections such as USB 3 and 10 Gigabit Ethernet to pass higher resolution samples at higher rates.
