Hi Hamed, consider noise. Any real-world communication is subject to it. Another thing would be sample clock offset, which you could reduce if you clock both X300 from the same reference clock, or the Clock ref out on the back of the first X300 and connect it to the Clock ref in of the second,

2 meters seems like an incredibly short distance unless you have an attenuator in series with the Tx antenna. You may be overdriving the receiver and causing distortion errors. @(^.^)@ Ed Sent from my iPhone > On May 12, 2023, at 8:10 PM, Hamed Al-Zubi wrote: > >  > Hello, > > I am utiliz

Ed,  I tried the NLOS scenario to avoid distortion, but still the same error occurs.  Thanks!HZ On Saturday, May 13, 2023 at 11:07:22 AM CDT, Ed Criscuolo wrote: 2 meters seems like an incredibly short distance unless you have an attenuator in series with the Tx antenna. You may be ov
