Dear Neel PandeyaI have test in the following setupCenter frequency: 5.89GHz (I am using the antenna supporting this center frequency)Sampling rate: 5MHzFrequency of sine wave: 1kHzFrom others’ comments, I realized that cancellation will not be successful if I do not calibrate LO offsets, which will result in frequency/phase offsets.Thank you.- Inkyu2018. 5. 21. 오전 9:47, Neel Pandeya <address@hidden> 작성:Hello Inkyu Bang:Just repeating what Marcus asked. What sample rate are you using? Is this USB 2.0 or 3.0? Could you post your flowgraph?--Neel PandeyaOn 24 April 2018 at 06:08, Marcus D. Leech <address@hidden> wrote:What sample-rate are you using?

Hi,
I am trying to use two USRP (B210) in one laptop.
I plan to send signals using two USRPs from the same source.
When I tried to separately run ".grc" file in each terminal, it works correctly.
However, when I tried to add one more "UHD: USRP sink" block in GRC.
It shows an exception message "S" and only one USRP works.
Could anyone help me to solve this problem?
(1) What is the meaning of "S"?
O: overflow, U: underflow, but I don't know what this is.
(2) Is there any way to use multiple "UHD: USRP sink" blocks in one machine?
Thank you,
Regards,
Inkyu Bang
Could you share your .grc file?
