[Discuss-gnuradio] Requested decimation is odd

[Ting Wu]

Hi all,

 

I am using USRP N200 with LFRX daughter board. The newest version of images has been loaded.

The sampling rate is set as 4 MHz. There is constantly a UHD warning:

 

The requested decimation is odd; the user should expect CIC rolloff.

Select an even decimation to ensure that a halfband filter is enabled.

 

How do I change the decimation value?

And what value should I set it?

 

Thanks!
