A firmware update brings the SignalShark application up to the latest state but does not change the SignalShark operating system.
The latest version of the SignalShark firmware (Application Version) is: 184.108.40.206
Requirement: Operating system version V2.0.6 or above
If you have operating system version V2.0.5 or earlier, a complete system update will be required in order to use the new firmware (see below).
The exact content of this version is described in the ReadMe file (included in the ZIP archive).
Warning: Downgrading to a previous firmware version is no longer possible after you have installed this firmware.
Narda MapTools is used to download Open Street Maps for use with SignalShark and IDA products. The latest version is found here:
The SignalShark Finder tool can be used to search for connected SignalShark devices in a network. In addition to the IP and MAC address, information about the firmware version, device name and serial number of SignalShark devices available on the network are listed. This information can be copied to the clipboard for further use in other programs. The tool also allows easy connection to a SignalShark via Remote Desktop.
Narda Script Launcher
In everyday work applications, measuring procedures may need customized adjustments. To meet also these special needs, SignalShark supports python based scripting. Narda Script Launcher allows SignalShark users to select and run scripts from within the SignalShark application.

NSL Script Packages:
The "copysettings" script copies selectable parameters such as Fcent, RBW and Attenuator from one task to another task.
The script "saveptable" allows to save the information of a peak table in CSV format.
The script "iqstreamcntr" allows to configure and start an IQstream easily.
The script "peaktrigger" uses the peak table view of SignalShark to stop the measurement when reaching or exceeding a user defined level.
The script "signalsharkwol" allows to switch on a network connected SignalShark via WakeOnLAN.
The script package "nslconverter", contains scripts for converting data formats.
SignalShark stores measurement data in HDF5 format. With the script "convertspectrum" you can convert spectrum data stored in HDF5 format to CSV format.
SignalShark stores measurement data in HDF5 format. With the script "convertsgram" you can convert spectrogram data stored in HDF5 format to CSV format.
The script allows to convert CSV based transmitter tables of the IDA into the XML based format of the SignalShark.
To do this, the corresponding transmitter table is marked in the PC software IDA-Tools and copied as CSV formatted text to the clipboard of the PC using the function "Copy actual View to Clipboard". The next step is to paste the contents of the clipboard into a text file and save it with the extension ".csv". When the script is executed, the user is asked for the CSV file to be converted and the file is then converted to the XML-based SignalShark format and saved.
The script allows to convert CSV-based service tables of the SRM into the XML-based format of the SignalShark.
To do this, mark the corresponding service table in the SRM-Tools/TS PC software and copy it as CSV-formatted text to the PC clipboard using the "Copy actual View to Clipboard" function. The next step is to paste the contents of the clipboard into a text file and save it with the extension ".csv". When the script is executed, the user is asked for the CSV file to be converted and the file is then converted to the XML-based SignalShark format and saved.
The script allows to convert CSV based transmitter tables of an Excel spreadsheet to the XML based format of the SignalShark. The user is provided with an Excel file as a template. After filling out the table, it can be saved in Excel as a CSV file. When the script is executed, the user is asked for the CSV file to be converted and the file is then converted and saved in the XML-based SignalShark format.
The script package "nslgnss" consists of several individual script files. It displays information about the current GNSS reception and issues a warning message if the quality of the GNSS reception falls below a certain level.
The script package "iqrecorder" consists of several single script files. It enables the recording of IQ data in WAV format.
Before recording, basic settings can be made in a dialog window.
For the recording there is the possibility to set the parameters Ftune and CBW via a Level Meter View. On the other hand, the Ftune parameter can also be set via the Peak Table View and a predefined trigger threshold.
The "nslremotedf" script package consists of several individual script files. It allows to create a localization with several SignalShark devices located in a network.
The SignalShark devices on the network can be listed and managed.
First, one configures a bearing in the main device as usual. Then the settings can be transferred from the main unit to all units on the network.
In an overview display, the "Spectrum View" of all SignalShark devices in the network can be checked.
Finally, a bearing is taken on all devices at the same time, if possible, and this bearing is saved in the main device in a new working directory. The main device calculates a localization from the bearings generated in this way and displays it on a map.
The package "nslcoveragemap" consists of several single script files. The user can configure settings for the coverage map and take location-dependent level measurements with distinct color-coding. The coverage map level measurements can be saved in CSV file format to be viewed later or to be converted into KML format for geographical data display.
The "nslmdoc" script takes a Word template file (.docx) as the basis for a measurement report.
It reads all settings from the current measurement, makes a screenshot of each view and generates a measurement report as MS Word document.
Narda Quick Guide
Quick Guide which explains how to develop Python scripts for SignalShark using the IDE software PyCharm. The ZIP archive also contains the PyCharm project "UserScriptDev", which can be used as a basis for your own projects.
The package "nsllimitline" consists of two main scripts which can be used for several limit line functionalities based on individual settings. It offers a spectrum view in which either a horizontal line or a reference measurement can be used as a limit line and displayed next to the current measurement result. Depending on the settings, the script displays a corresponding message when the reference is exceeded or undercut, plays a sound, takes a screenshot and saves the measurement.
The script package "nsldfautopilot" offers the possibility to connect a SignalShark basic device to the navigation software "Navigator" of the manufacturer "Mapfactor" (https://navigatorfree.mapfactor.com) and to set the localization result of the SignalShark as destination in the navigation system.
The navigation software is freely available and can be installed on a smartphone or a computer. The communication between SignalShark and the navigation software is done via text-based commands, which are transmitted via TCP network connection. The network connection can be established via Wi-Fi or Ethernet cable. For controlling the navigation software via TCP, the activation of a paid option in the navigation software is required.
The script package "nslchscanner" consists of several individual script files. It enables the monitoring of predefined channels in the spectrum. This is comparable to a channel scan on a radio. If one of the monitored channels exceeds a definable level value, a previously user-defined action ("Action") can be executed.
