[Discuss-gnuradio] Phase Difference

2012-10-21 Thread Shih Oliver
Hi lists, I'm using a e100 to send a sinusoid signal to only one N200 through a splitter. The two received signals by the same N200 still shows a phase difference, and it appears that the phase differs from different runs. What should I do to get rid of the phase difference? Many thanks i

Hi lists, I'm using a E100 to send a sine wave to two N200 by going through a splitter and I'm trying to synchronize the phases between the signals recieved by the two N200.Both of the N200 have internal GPSDO with the gps locked and the same gps time. However, they are still not in

Hi, I'm trying to synchronize two N200s in phases with both of them having GPSDO inside. I followedthe instructions on ettus for synchronizing channel phase. However, I got error message as follows, UHD source block got error code 0x2gr_block_executor: source produced no output. We're

Hi, I'm using the lfrx board and try to turn off the DC offset correction but it seems no change in the data collected.I'm wondering if I did it wrong and here's part of my code:self.uhd_usrp_source_0 = uhd_usrp_source() self.uhd_usrp_source_0.set_auto_dc_offset(0, 0) Also I am
