Each model of remote spectrum monitors contains an embedded web server. Using a browser (Google Chrome and Firefox are supported), users can access the graphical user interface (GUI) and send control commands to the remote spectrum monitor. Tabs and Setup Panels can change location in the web browser depending on the size of the browser.
The following figure illustrates some of the key information areas of the Remote Spectrum Monitor GUI. The graphical user interface primary components are:
• Web Address
• Instrument Settings Summary
• Measurement Display
• Spectrogram
• Setup Panels
The secondary components on the GUI include:
• Instrument Model Number
• GPS position of the Remote Spectrum Monitor
• Date and Time
• Start/Stop/Center Frequency
• Markers
• Limit Lines
Remote Spectrum Monitor GUI Overview
Web Address
This is the IP address of the Remote Spectrum Monitor. The IP address of the instrument can be entered into the Web Browser’s address window and the Remote Spectrum Monitor web server will display.
Instrument Settings Summary
The Settings Summary lists the current settings for the reference level, input attenuation, RBW, VBW, sweep mode and type, and display points of the instrument.
Measurement Display
The measurement display (sweep window) provides measurement trace data. Markers and limit lines are also displayed here. Above the top left corner of the display is the Remote Spectrum Monitor’s model number. Next to the Model Number is a listing of options (if any) for the instrument. Below it is the label/name given to the RSM unit by the user. Above the top right corner of the display is the GPS location of the Remote Spectrum Monitor and the current date and time. At the bottom left and right corners of the display are the start and stop frequencies. At the center are the center frequency and span. Adjacent to the left edge of the display is a color bar that indicates the power level of the trace and is reflected in the spectrogram. An image of the measurement display can either be saved or copied by right clicking on the display and selecting the desired function from the pop-up menu.
Spectrogram
Spectrogram is a representation of the frequency spectrum as it varies with time. Color is used to represent power levels. This feature is useful for identifying intermittent interference and for observing changes in frequency over time.
