 <p>The sample rate of the Azigram output can be&nbsp;chosen from the&nbsp;Output panel of the settings. The plugin uses frequency domain downsampling in order to acheive the&nbsp;selected sample rate. When selecting the output sample rate, the output FFT length and FFT hop will be altered in order to maintain&nbsp;the same time and frequency resolution as the upstream FFT module.</p>

The test signal is a simulated DIFAR source with 8 short FM downsweeps arriving from 0-315 degrees in 45 degree increments. The bottom panel shows the PAMGuard Data Model.</p>
