Subject: | [Discuss-gnuradio] 1 PPS for USRP2 ? |
Date: | Tue, 23 Mar 2010 14:09:18 +0530 (IST) |
Hi, I am trying to synchronize two USRP2's using GPS receiver of 10MHz and 1 PPS. recently ,i ran into some problem with 1 PPS output from GPS receiver, but output clock 10 MHz seems to be perfectly alright. 1) Do i really need 1 PPS input along with 10MHz Clock for USRP2....? 2) Is it not possible for me to use only the clock 10MHz and not the 1 PPS, to synchronize 2 USRP2's. 3)If it really needed, then can i generate 1PPS from signal generator and feed it to USRP2., but if i do that, How do i sync the rising edge of the 1 PPS to the Rising edge of the Sine wave(10MHz) ? Thanks KRISHNA S |
