[Discuss-gnuradio] change center freq of usrp_source block automatically in incremental way

[MITUL VEKARIYA]

Hi

I want to make block diagram in grc such that the center freq of usrp_source should be automatically changed in incremental way defined by min and max boundary. I don't want to take input from qt-qui slider.

Just like the example of usrp_spectum_sense.py but in grc.

How can I do that?

Thanks
