The SignalShark from Narda Safety Test Solutions is a Real Time Handheld Spectrum Analyzer that operates from 9 kHz to 8 GHz. It can be used for a number of use cases, weather making a wideband measurement of an entire frequency range, or detecting hidden signals, or reliably capturing very short impulses, or localizing interference signals. This real time analyzer was developed in conjunction with practical market analysis and targeted user surveys. Its ability to make powerful real time measurements with a real time bandwidth of 40 MHz in a handheld design will help accelerate the development of mobile technologies within the industry. It will also assist mobile service providers and authorities to ensure interference free networks and support regulators in providing protection from illegal transmitters and hidden signals. The modern user interface of the SignalShark combined with a 10.4 inch touch screen makes it easy to carry out a large number of measurement and analysis functions. It can be adapted in advance to the measurement tasks and users needs, facilitating clear, effective and reliable measurements for both beginners and experts. The two Li-ion batteries can be hot swapped during operation, making it possible to operate the device for long periods in mobile applications. The robust design conforms to MIL standards, enabling the SignalShark to make reliable measurements even under harsh environmental conditions, delivering precise results.
