Feature custom definition of Radio Standard channels. 

You can now import standards or define your own channels to be included in the Spectrum Analyzer graph.

Each channel in a Radio Standard will display:

Table of available radio standards and related configuration.

Each row is one radio standard (example: WiFi 5GHz). Click a row to select it. The selected row is highlighted. Use the scroll bar on the right of the table to view more items.

Name

Displays the standard name as it will appear across the software (lists, selectors, overlays).

Enable

Turns the standard on or off for use in the application.

• Yes: The standard is available in selectors and can be used for channel lists/overlays.
• No: The standard is hidden or unavailable where standards are used.

Channels

Shows how many channels are defined for that standard.
This is useful to confirm the standard includes the expected channel plan.

Style

Controls how the standard is drawn when shown as an overlay or reference on the spectrum display.

• Solid: Continuous line (best for general use).
• Dashes: Repeating dash segments (easy to spot over busy traces).
• Dotted: Small dot pattern (subtle, low-visual-impact reference).
• DashDot: Alternating dash and dot (distinct when multiple overlays are shown).

Background

Controls whether the overlay uses a filled background behind the standard/channel shapes.

• Yes: Filled background (better visibility on noisy traces).
• No: Outline-only (less visual obstruction).

Border

Controls the outline type of the overlay.

• Rounded: Rounded corners (smooth, readable blocks).
• Bell: Bell-shaped profile (curved “bump” style outline).

This section shows the parameters of the currently selected row.

Selected Radio Standard

Confirms which table entry you are viewing/editing.

Frequency Range (MHz)

Shows the full frequency coverage of the standard in MHz (start to stop).

Channels Bandwidth (MHz)

Shows the reference channel bandwidth used by the radio standard.
If the channels have different bandwidths, it will be marked as “Mixed.”

Color

Shows the overlay color used to draw the standard.
Tip: Choose a color that contrasts with your trace and grid for easy reading.

Description

Brief explanation of the standard and any notes

This window shows (and lets you define) the channel inventory for a selected Radio Standard.

Channel Inventory

The table lists all channels included in the current Radio Standard and related frequency configuration defined.

Radio Standard Name

Shows the standard currently being edited.

Channels Start Freq (MHz)

Start frequency used to generate channels when you add them in bulk.

Channels Distance (MHz)

Frequency step between consecutive channels when bulk-generating channels.

Channels Bandwidth (MHz)

Bandwidth assigned to newly added channels.

Total Channels

Shows the total number of channels currently defined for this standard.

Channels to add

Sets how many channels will be added or removed at once.

Add Channels

Adds the specified number of channels using. New channels are appended to the inventory and appear in the table.

Remove Channels

Removes the selected channels from the inventory.

• The first line must contain the header --RFERD01.
• Optionally, additional details about the Radio Standard can be added as comments, prefixed with --.
• Define the Radio Standard Name, displayed in graph.
• Specify the number of channels, which must match the channels listed below.
• Define the Channel Bandwidth (MHz), a single value shared by all channels.
• For each channel, specify its name and center frequency (MHz), ensuring the total number of channels matches the previously defined value.

These files are text files you can edit or create with the tool of your choice (e.g. notepad – although we recommend some better editor such as Notepad++)

• XML file (UTF-8).
• More structured and easier to validate programmatically.
• Designed for richer channel definitions.

Key characteristics

• Each channel can have its own bandwidth.
• You can mix channels with different bandwidths in the same standard (for example 5/10/20/40 MHz).
• More fields can be added in a controlled way in future versions (without breaking the layout).

Advantages of .rfersx

• Variable channel bandwidths within the same Radio Standard.
• More readable structure for large standards (XML hierarchy instead of long text blocks).
• Less error-prone imports:
  • Channel fields are explicit (Name / CenterMHZ / BandwidthMHZ) and don’t depend on line order as much as text files.
• Better for automation:
  • Easier to generate and parse with tools/scripts that already handle XML.

On this screen you control how Radio Standard channels are drawn and labeled on the Spectrum Analyzer graph. These settings affect the channel overlay visibility and text readability.

Radio Standard Appearance

Use these options to change the channel overlay shape and orientation.

Show Channel Shape

• ON: Draws the channel shape/outline for each channel on the graph.
• OFF: Hides the channel shapes. (Text labels may still be shown if enabled below.)

Vertical Text

• ON: Rotates channel text so it reads vertically on the graph.
• OFF: Shows channel text horizontally.

Radio Standard Text Settings

Use these options to control which channel labels are shown and how large they are.

Show Channels Name

• ON: Displays the channel name label (example: CH 36).
• OFF: Hides channel name labels.

Show Channels Amplitude

• ON: Displays a channel amplitude label near each channel (based on the channel power/amplitude computed by the software).
• OFF: Hides channel amplitude labels.

Size

Controls the text size used for channel labels on the graph.

Options: Very Small, Small, Normal, Large and Very Large

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.

These files are text files you can edit or create with the tool of your choice (e.g. notepad – although we recommend some better editor such as Notepad++)

Technical Support

Create a compressed ZIP file with activity logs, configuration files and report files in order to diagnose application issues. Only required if requested by RF Explorer Tech Support. 

Factory Default

Restore system configuration setting to Factory Default values. Licenses will be preserved, but Presets and other preference settings will be lost.

Language

The application includes a Language Options feature that allows users to change the interface language according to their preference.

Multilanguage support for English (EN), Spanish (ES), German (DE), French (FR), Japanese (JA), and Chinese (CH).

This improves usability for international teams and helps reduce mistakes in operational environments where technicians work in different languages.

Diagnostic Report

This function generates a comprehensive PDF document that contains:

• System information: hardware details, firmware version, and operating status.

• Configuration settings: current application parameters and user-defined options.

This report can be shared with technical support to facilitate faster issue resolution or stored as a reference for maintenance and audits.
