Hello everyone--

I want to know how to disable  the DC offset. If I  execute the  set_auto_dc_offset(false) command  it will work ? 

Regards,

RP

Thanks for the response. I am actually new in this area.  it happens around18th  sample And I don't know whether it gets the signal and then lose it or it is just DC offset ? Does it catch any signal?

cheers, 

RP

Is this at the beginning of a burst receive? It might be the DC offset
removal filter. You can try disabling that with set_auto_dc_offset(false).
