The main menu is designed in a easy to use, hierarchical layout on the right-side of the device screen as depicted in below screen.

The main screen includes standard spectrum analyzer graph with captured data from RF Explorer handheld analyzer or IoT module and the right-side menu with all options to use the application easily.

The data screen is a high speed data representation of Spectrum Analyzer Frequency vs Amplitude.

The X axis represents frequency in MHZ and Y axis display actual received power in dBm, dBuV or Watt (selectable).

You can use two finger gestures to zoom and pan frequency or amplitude.

• Zoom in/out - change Frequency Span: Apply two finger gesture towards the horizontal axis to increase or decrease span.
• Amplitude pan: Move two fingers up or down to pan amplitude
• Frequency pan: Move two fingers left or right to pan frequency 

The navigation bar provides full control to review any past sweep event and also replay sweeps at original captured speed.

This can be used with recently captured data or stored data files.

• [<<]: Go back multiple sweeps (about 10%)
• [ < ]: Go back to previous sweep
• Navigation bar: Point and move to desired sweep. While the scrollbar actuator is being moved, sweep captured date will be updated realtime but spectrum analyzer screen will be updated after releasing the bar.
• [ > ]: Go forward one sweep
• [>>]: Go forward multiple sweeps (about 10%)
• [Play]: Replay captured activity using original captured speed
• [ || ]: Pause spectrum analyzer activity on screen, but the RF Explorer device continues capturing and storing data
• [ Hold ]: Fully stop spectrum analyzer activity and data capture. This is the only valid state when using data from file
• [ Live ]: Restore spectrum analyzer activity and data capture

Some parameters can be easily configured by screen touch or click marked with red areas in picture above.

This special mode in the Spectrum Analyzer screen displays WiFi channels for 2.4Ghz and 5GHz - only available in RF Explorer devices supporting the specific frequency range.

Display view for channels 1-13 including center channel frequency and channel power.

The higher power channel detected is depicted in a different color.

Display view for 28 channels defined for 20MHz width, including center channel frequency and channel power.

On top of 20MHz channels, 40MHz, 80MHz and 160MHz channels are displayed.

• Red - 20MHz channels
• Green - 40MHz channels
• Blue - 80MHz channels
• Magenta - 160MHz channels

This is a powerful, high performance 2D/3D visualization of historical sweeps, displaying the most recent captured sweep in front, with older sweeps in the background.

It is a very efficient and practical way to display intermittent or time-changing signals that may not be easy to detect any other way.

Right click on the waterfall screen anytime to enable a context sensitive menu.

An advanced and powerful tool in the spectrum analyzer mode is the ability to work with Minimum and Maximum Limit Lines.

These are fully configurable, visual and optionally audible alarm feature with multi-data point lines to determine power limits.

Operative Limit Line

Limit Lines are fixed thresholds, and only one pair of Max / Min limit lines can be specified at any given time.

These settings apply to one limit line type at a time: maximum or minimum. Use to define or change parameters of each limit line as required.

Different limit lines can be loaded from file or generated from a signal trace anytime.

Limit line type

• Max: select to apply changes to maximum limit line.
• Min: select to apply changes to minimum limit line.

Build from signal

Generate maximum or minimum limit line from a currently selected signal trace specifying a positive offset in dB. This offset will be added or subtracted depending on limit line type selected

Save to file

Save maximum or minimum limit line to a limit line file (.rfl).

Read from file

Load maximum or minimum limit line from a limit line file (.rfl).

Remove

Remove maximum or minimum limit line from spectrum analyzer screen.

Common

These settings apply in common to both maximum and minimum limit line

Sound alarm

To enable or disable an audio alarm for as long as the condition is not met

Grips

To enable or disable circle gripped in limit line traces. For high resolution mode, circles might make it hard to see how close limit line trace from signal trace is.
