Handheld spectrum analyzers - Narda's SignalShark impressive in direct comparison test

(PresseBox) ( Pfullingen, Germany, )
How do the best currently-available handheld spectrum analyzers and radio frequency receivers match up in a direct comparison test? In a fair, neutral contest under similar conditions? And, above all, which device finishes ahead of the field in key parameters such as sensitivity and harmonics, intermodulation and dynamic range? Narda STS has recently put up a video comparison on its YouTube channel. This 20-minute instructional audiovisual presentation answers all of these questions fully. As well as giving detailed test results and describing the test conditions, this video clip also provides valuable insights into one of the most complex disciplines in measurement technology. In short, it is an absolute “must see”.

In the video, Narda’s SignalShark challenges the established reference instruments to an open contest in a series of analytical tests. Pitted against the newcomer in the field of real time handheld analyzers are the Anritsu Spectrum Master, Tektronix H500/600, and the PR100/DDF007 from Rohde & Schwarz. The result—this much can be revealed—is that the challenger leaves its competitors well and truly behind. This informative and instructive English-language film is now available on YouTube. Simply type “test narda signalshark” into the search box online and click to start the “SignalShark’s success story”, a professional demonstration that has the potential to shake up the entire RF industry.

A handheld device with 40 MHz real time bandwidth, the dynamic range of a benchtop instrument, and intrinsic noise, IP2 (harmonics) and IP3 (intermodulation) that match ITU measuring receiver specifications: The result is a foregone conclusion in view of these outstanding technical parameters of the SignalShark. At the finish, there can be only one winner: Narda’s current flagship takes first place unopposed and by some margin. The competition from Anritsu, Tektronix and Rohde & Schwarz is left well behind. The positive results of tests on further parameters such as RF performance, measurement speed, input attenuation and detection shown in the video only serve to underline the superiority of the SignalShark in this comprehensive series of tests.

Narda has clearly touched a nerve in the RF industry with this comparison test, with its clear results that can be professionally verified and scientifically reproduced at any time. The thousands of hits registered in the few weeks since the video was published speak for themselves. However, that is only part of the story. The real value of this video lies in the depth of information in the explanations of the subject matter, alongside the facts and figures, and the meaningful results of comparison with other manufacturers’ devices. Viewers are not left with just the bare facts. To make everything understandable, the presenter explains step by step important details of the methodology and special features of the investigations, as well as simply explaining the basic relationships in the highly complex field of RF measurement. One example of this is the immense importance of the dynamic range in relation to RF measurement procedures. These explanations make the test results and findings in this video more accessible to a wider audience.
