Narda Safety Test Solutions was founded on January 1, 2000. The company is an offshoot of the high-frequency measurement technology operation of the former Wandel & Goltermann group and has been a part of the L-3 Communications technology group since it was founded. The operational field of Narda Safety Test Solutions covers the business segments of RF Safety, EMC, and RF Testing. In all three of these areas, Narda is one of the leading providers of high quality, application tailored measurement solutions. We do not develop any products without first consulting a large number of customers. In this way, we can be certain that the practical know-how of the people on the ground is reflected in our products and will penetrate the market.
One part of the competence of Narda Test Solutions results from extensive high-frequency and microwave know-how gained through years of experience. Highly specialized engineers in our development unit make use of the latest hardware and software tools and materials to ensure that our customers can obtain stable and reproducible measurement data.
In addition to this, Narda has for more than 20 years now cultivated a worldwide, focused network of partners who are responsible for advising our customers and marketing our instruments. We are particularly interested in ensuring that these partners receive regular trained and further technical instruction.
We have become global market leaders with many of our products. We are well aware of the responsibility that this brings. It is our goal to cultivate long-term relationships with our customers and to constantly demonstrate our trustworthiness as a partner through high quality, precise, reliable and long-lasting products.
Quality is the watchword for Narda Safety Test Solutions GmbH and a promise to our customers to live up to their and our expectations for performance and reliability with our products and services.
Our products satisfy specific market requirements and are eminently suitable for the stated field of application. We are able to achieve this standard by consistently including our customers in the process of maintaining our existing range and the development of new products, as well as by constantly enhancing our test and calibration methods, particularly the accredited ones. The calibration laboratory carries out its work according to the processes, specifications and instructions described by the company, regardless of any management directives.
Because we are aware of the risks attached to the supply of possibly defective measuring equipment, no device leaves our factory untested or uncalibrated. Proof of this is kept on file.
We use a management system to ensure the long-term quality of our products and the development capability of our company. This management system describes and defines how we are organized and how we operate, and is the starting point for all improvements. Our management system covers all areas and implements the requirements set out in the ISO 9001/2008 and ISO/IEC 17025 standards.

IDA 2 Reveals Interference In Complex Signal Structures
Today’s conventional spectrum analyzers that utilize the super-heterodyne principle can not adequately investigate wireless signals. Spectrum analyzers must use digital signal processing and wideband FFTs to be able to distinguish closely spaced signals, and to reliably detect overlapping signals. The IDA 2 can be used to simultaneously measure wireless signals with microsecond time resolutions, and frequency resolutions of a few Hertz. This application note discusses the practical uses of the IDA 2’s high-resolution analysis of wireless signals.
IDA 2 Provides New Opportunities For Clarifying Wireless Signals
The IDA 2 from Narda Safety Test Solutions now has a time resolution as small as 1 μs that offers new insights into new signal structures. Interference and hidden transmitters with rapidly changing frequencies can now be revealed, analyzed and localized.
Interface And Direction Analyzer: User-Generated Maps In IDA 2
Having your own maps, aerial photographs, orthophotos, or satellite images appear on your infrastructures is much more useful than having them spread out on different displays. The open source Slippy Map Tile System from OpenStreetMap is implemented in Narda’s IDA2. By using the IDA 2, maps are displayed quickly and are supported by many GIS programs, allowing for ease of map creation.
Recognizing and Separating Signals in Spectrograms
This application note describes the advantages of the IDA 2 High-Resolution Spectrogram through a demonstrated practical example.
Receiver and Spectrum Analyzer: IDA 2
This application note discusses the IDA 2 and the difference between using it as a spectrum analyzer and a receiver.
Narda Safety Test Solutions Discusses Their IDA 2 and the Future of Test & Measurement
In this interview with RCR Wireless, Volker Brands, the regional manager for Narda Test Solutions, is describing the launch of the second generation of hand-held spectrum analyzers, IDA2, for interference and direction finding.
Using The IDA-3106 For Rapid Systematic Detection And Geographical Localization Of RF Signals In An Unknown Environment
This Application Note describes a method using the new IDA-3106 handheld receiver with on-board spectrum management and direction finding functions, which is particularly suitable for use by special forces during tactical operations. One application scenario is the rapid systematic detection of unwanted or unauthorized communications during field operations and their elimination through tactical countermeasures such as active jamming. Another scenario is support in combating criminal or paramilitary activities and capturing the perpetrators by tactical localization of the communications equipment used without attracting attention.
How To Use Jammers Effectively
Interfering with or suppressing wireless links is prohibited globally. There are, however, exceptions to this general rule, which always require the official consent of the national telecom authorities. This application note looks at the effective legal application of jammers using a GSM link as an example. The results also give some indication of how to trace illegal jammers.
Continuous GSM Interference From Intermodulation
This application note discusses a case in which a continuous impairment in the GSM 900 band was affecting a cell phone station’s performance, and how Narda’s IDA 2 interference and direction analyzer was able to help.
Capturing IQ Data With NRA And IDA Technical Note
With the Scope/IQ option, the NRA and IDA instruments allow you to generate IQ data from the received data and display, demodulate, and store them, and transmit them block by block or as a continuous stream via a remote interface. What, though, is the significance of this I/Q data? What are they used for? And, how are they obtained using NRA and IDA?
Basic Insights – Safety in Electric, Magnetic, and Electromagnetic Fields
This article discusses the basic principles of EM fields, the potential biological effects they can have on the human body, and protective measures one can take to ensure their safety.
Measuring and Monitoring Satellite Signals
Measuring and monitoring the signals in satellite communications systems is as complex as the tasks of those involved in operating such systems. Satellite operators are normally interested in ensuring that transponder use corresponds to the criteria agreed with users in terms of quality and scope, which also includes the detection of any interference signals. Teleport operators are concerned with making the best possible use of the resources with the communications systems, particularly the space segment. This Application Note describes example measurement principles that cover the above-mentioned applications and for which the NRA range of spectrum analyzers from Narda is particularly suitable.
The Signal Beneath The Signal: IDA 2 Makes Payload And Interference Signals Clear
Detecting RFI, revealing the causes of interference, locating unauthorized transmitters – all these are tasks performed by modern direction finding equipment. Spectrum analysis and time domain displays give much information about the type of signal, but they don’t reveal everything. They are limited to recording the amplitude versus frequency and / or versus time, and often lose information due to display compression. The full picture is only seen when the measured values are recorded without compression and separated into their real and imaginary components, usually referred to as the in phase and quadrature components, or I/Q for short.
