File Configuration

Save RFE Data File on Close

Save a RFE data file every time application is closed. If “Enable Continuous Log” option is enabled, this feature will be enabled automatically.


Enable continuous log to save RFE data or CSV files periodically in seconds as selected in “Auto Save Delay (s)” option. Also this option save a RFE data file in each configuration change in device and when application is closed.

Auto Save RFE Data

If “Enable” option checked, save a RFE data file every number of seconds selected in “Auto Save Delay (s)” option.

Auto Save CSV

If “Enable” option checked, save a CSV data file every number of seconds selected in “Auto Save Delay (s)” option.

Auto Save Delay (s)

Number of second for Auto-Save feature.

Auto Delete (Days)

Number of days for Auto-Delete old and unused files in user folder

Auto Save Folder Path

Directory where .RFE and CSV files will be stored if Auto Save feature is active

CSV File

config CSVfile

Field Separator

Delimiter to use for CSV file generation. Supported separators: Comma, Division, Semicolon, Space or Tabulator.

Decimal Separator

Delimiter to use as decimal separator. Supported separators: Comma or Dot.

End of Line

End of line to use in for CSV file generation. Supported end of lines: Line Feed (\n) or Carriage Return and Line Feed (\r\n).

WSM Sennheiser Compatible

When option is checked, CSV files generated can be imported directly in WSM Sennheiser software.

CSV Trace

Selected data trace used to generate the CSV file. There are multiple traces available (such as Real Time or Average) so it is important to select the right one for your needs.

Important: The selected trace must be visible in the Spectrum Analyzer graph, if there are multiple visible the tool will select one by this priority order:

1. Average trace
2. Max Peak trace
3. Real Time trace
4. Max Hold trace
5. Minimum trace

CSV Header

Insert descriptive header inside generated CSV files.

Fields included are: 

  • Receiver
  • Date/Time      
  • RFUnit
  • Owner
  • ScanCountry 
  • CRC

Radio Standards

radio standard

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 of RF Explorer Touch. Each channel in a Radio Standard will display:

  • Channel name
  • Visual shape of the actual bandwidth and channel position
  • Computed individual power channel

Radio Standards

All parameters of a Radio Standard can be configured in the menu option Config -> Radio Standards -> [Configure...]
This will open a configuration dialog to setup parameters, select which Radio Standards are visible (up to 10 at any given time), import new Radio Standard definitions, etc.

rs settings

File format

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++)

Limit Lines

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.

config limit lines

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 maximum or minimum limit line from spectrum analyzer screen.


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

Note: The alarm sound type is preconfigured, but can be easily customized by replacing the file notify.wav from the RF Explorer application data folder (%appdata%\roaming\rfexplorer). The file can be any valid .wav file. The minimum duration of the audio alarm is that of the duration of the .wav sound file.


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.
