Peak selection assistance for rf spectrum analysis

A non-transitory computer-readable storage medium comprising instructions that, when executed, cause a processor to perform the steps of:

• providing a user interface on said RF spectrum analyzer, comprising a display of said spectrum trace that is generated from trace data representing RF signal amplitude values as a function of frequency and obtained using the RF spectrum analyzer;
• from user interaction on said user interface, defining a window along a frequency axis of said spectrum trace, the window comprising a lower edge and an upper edge visually represented on said display;
• selecting a subset of said trace data using said first edge and said second edge of said window as defined along said frequency axis;
• determining a maximum of said amplitude values within said subset of said trace data;
• determining a corresponding frequency value for the maximum amplitude value;
• and
• outputting said maximum amplitude value and said corresponding frequency value to a user.

An RF spectrum analyzer device comprising:

• an IQ data acquisition device and a digital signal processing module for measuring trace data representing RF signal amplitude values as a function of frequency;
• a processing unit receiving the trace data and configured for:
• providing a user interface comprising a display of a spectrum trace that is generated from trace data;
• from user interaction on said user interface, defining a window along a frequency axis of said spectrum trace, the window comprising a lower edge and an upper edge visually represented on said display;
• selecting a subset of said trace data using said first edge and said second edge of said window as defined along said frequency axis;
• determining a maximum of said amplitude values within said subset of said trace data;
• determining a corresponding frequency value for the maximum amplitude value;
• and
• outputting said maximum amplitude value and said corresponding frequency value to a user.

A method for identifying a maximum value in a section of a trace displayed to a user on a RF spectrum analyzer interface, comprising:

• providing a display of said trace using trace data including frequency and amplitude components on said RF spectrum analyzer interface;
• providing a movable window with a first edge and a second edge and a width between said first edge and said second edge, adapted to be displaced by user interaction along a frequency axis of said trace;
• receiving an indication that said movable window is at a chosen position along said frequency axis;
• selecting a subset of said trace data using said first edge and said second edge at said chosen position along said frequency axis;
• determining a maximum of said amplitude within said subset of trace data to obtain said maximum value;
• determining a corresponding frequency value for said maximum value;
• providing information about said maximum value of said amplitude and said corresponding frequency value.
