Dedicated analysis disables the normal scan pattern for a Sensor. Then, it conducts a detailed spectrum scan and displays the results in the Spectrum View window.
This usually will happen if you only have one radio turned on. If you continue, your wireless application may be disrupted but Spectrum Analysis will run.
Select File > Close to exit the Spectrum View window. You will be prompted to save the scan to an ADSP file. An ADSP file can be opened by navigating to Menu > Open > Spectrum Analysis.
