We're marking it DONE./ See also the attached screenshot for settings used on the block. I tried assigning the second device an IP of 192.168.10.3 and removing the second Ethernet cable, but then the device is neither detected by uhd_find_devices nor within GRC. So how can I get both devices sample synchronously with the uhd multi_usrp source block?

Make sure uhd_find_devices finds your device.

2500M, gain 20 and if i were to change a few things around like for example the frequency to lets say 2450M or 2000M (Its a different band) but regardless it just produces the same error but this time with a different set of numbers . 3) RFX2400 daughter boards Thank you so very much for your quick reply again, Anay.

2)The values that im passing to the program is the frequency -> 2500M, gain > 20 and if i were to change a few things around like for example the > frequency to lets say 2450M or 2000M (Its a different band) but regardless > it just produces the same error but this time with a different set of > numbers . > 3) RFX2400 daughter boards > > Thank you so very much for your quick reply again, > Anay. > > So, to be more specific. Which function in the UHD API are you calling that causes this error? Is it usrp->set_rx_freq()? Can you demonstrate the problem with any of the example applications: examples/rx_samples_to_file --rate=1e6 --freq=2450e6 -Josh

measurement accuracy as well as minimize the IQ imbalance, DC offset etc. We do have all sorts of measurement equipments in our lab. Thanks Muhammad Abdul Hadi Lecturer PSATRI, King Saud University Saudi Arabia

, it would be good to find a link to it. LVDJ
