Hi there,

I am using the FMCOMMS3 board along with the zedboard. I am have problems with the RX baseband DC tracking because I am seeing a large DC offset on the RX channel (RX1), and it seems to be related to the fact that my RF signal is in burst mode (has a duty cycle of 8ms on and 1ms off). I am using the 'No OS' software supplied, with minimal changes. If you have any ideas as to how I could fix this, I would appreciate any hints.

regards,

Maeve
