Hi Jermy, 1PPS requirement is not mandatory. To acheive synchronization between two USRP2's i have done the following, 1) Change the firmware in both USRP2's SD card in txrx.c i have added clocks_enable_test_clk(true,2); clocks_mimo_config(MC_WE_LOCK_TO_SMA); just before whilr(1) loop 2) i have connected 1 GPS source providing reference CLOCK 10 MHz 1.2 Vp-p, to 2 USRP2's with a T-splitter. If not GPS, u can also use signal generator, generate a 10MHz 1.2Vp-p and feed this to the REF CLK of USRP2. This should solve the Synchronization problem.
