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

If you're willing to analyze offline, there's a nice spectrum display tool called inspectrum.

Here's an example of OFDM pilots in an ATSC 3.0 signal.

Hi Muhammad - Marcus had a straightforward solution, but there is
another solution - which may or may not work for you and your exact
flowgraph.

You can directly take a FFT of the signal.

Then display it in a QT GUI Vector Sink - In the Vector Sink you can
adjust the X and Y axes.

Just an alternative - Hope this helps.
