Re: Limiting X-axis Scale in GNU Radio QT GUI Frequency Sink Block

Hi Muhammad,

you simply resample to that bandwidth before feeding into the frequency sink. Note that
the labels on the x-axis are only derived from the bandwidth you set in the frequency
sink; in fact, the frequency sink knows nothing about "real" frequencies, it only sees the
sample values, so all things it does are scaled to the Nyquist bandwidth.

Best regards,
Marcus
