USRP2 with XCVR- External Clock Setting

GNU Radio
1

Hello

I want to implement an OFDM Transmission at 2.45GHz, and the internal
USRP2 oscillator has a deviation at about 22kHz. That is too much and
interrupts the (software) synchronisation.

Because of that i want to use an external clock 10MHz with the USPR2.
It shoult be about 5dBm - 15dBm and with an amplitude about Upp = 3V.
An square wave should be best, but also a sinus should do it.

The question is: Where should i adjust the settings so the USRP2
will use the external clock ?

I use it with the Matlab Simulink and the standard firmware image.

I appreciate your hints
Vlad

Might I suggest that you post your question to either the usrp-users
mailing list, or one of the MathWorks user support forums instead?

Ok, thanks ! I didn t know that there is a usrp users mailing list.
