For the first time, SignalShark XT users can run computationally intensive third-party software directly on the instrument, eliminating the need for an external computer during field operations. Target scenarios for the SignalShark XT include applications within large, distributed monitoring networks and TDOA-based signal source localization, sensor fusion (e.g., for stationary border surveillance), and containerized solutions, as well as all platform-based operations such as those performed on vehicles or masts.
In typical system architectures, receivers and analyzers remain in operation in the field, while more computationally demanding software, such as that used for signal classification, decoding, and demodulation, or high-performance IQ data processing, runs on a separate laptop. This entails additional hardware, extra external power consumption, more interfaces and cabling, and a significantly higher susceptibility to errors. These negative side effects, in applications for BOS, critical infrastructure operators, or systems integrators, already translate into greater system complexity, additional effort, extra costs, and a higher probability of failure.
In the military sphere, on the other hand, where reliability and robustness are in addition to extremely high computing power with no alternative, each of these parameters can be "decisive to the outcome of the war" and determine the success or failure of entire missions. The advantages of the SignalShark XT for field use stem from the conceptual reduction of system complexity. The mere fact that an external laptop is not required saves space and costs, and eliminates the need for a separate operating system requiring maintenance, an external power supply, and weather protection. With fewer system components and, therefore, fewer interfaces and connections—which also leads to a lower propensity for errors, including cybersecurity risks—the measuring instrument is easier to configure and ready for safe use.
The CPU, approximately four times more powerful, along with the open platform and greater system integration of the SignalShark XT, also have a positive impact on the defense sector in many respects. Narda STS has adapted the entire concept to the specific requirements of field operations. The compact device does not need to be radio-connected to other systems. It operates even in radio silence. Thus, the reduced system complexity generally leads to a lower electromagnetic footprint in crisis operations. When using the SignalShark Outdoor XT in the field, thanks to its integrated high-performance computer, it is no longer necessary to erect a separate mast on-site. Previously, in addition to the location antenna (ADFA) or a monitoring antenna, the receiver had to be connected to it. Furthermore, the PC and modem connections, including switches for the cabling and perhaps the two antennas, had to be made in a kind of enclosure. The device, already assembled in a compact system, is installed in about 10-15 minutes and is ready to use. After this brief period of time, the unit can be withdrawn from the direct line of fire, as the SignalShark XT can operate autonomously or be remotely controlled from a safe position.
The new SignalShark XT features, for the first time, a powerful eight-core CPU with 16 GB of RAM, a 512 GB SSD, and 2.5 Gbit Ethernet. It is now possible, for example, to effortlessly perform simultaneous decoding and demodulation of 100 FM channels (instead of 16 in the standard version), as well as AI-based signal classification and offline direction finding, e.g., for locating a swarm of drones. With the new SignalShark XT, machine learning and reinforcement learning AI applications are also now possible, achieving excellent results in signal classification even when, for example, the user does not have all the necessary decoders available in the field.
SCPI remote control and VITA-49 compliant IQ streaming complete the new device's integration potential. Beyond increased computing power, Narda STS has achieved improved frequency accuracy of 0.2 ppm, as well as IQ streaming with a bandwidth of 40 MHz (up from the previous ~20 MHz). Available in the SignalShark Handheld XT, SignalShark Remote Unit XT, DF Receiver Module XT, and SignalShark Outdoor XT models, the newest member of the SignalShark family is based on Windows 11 LTSC 2024 and offers a "true open platform." This means users are not limited to pre-installed features or proprietary software. Instead, they can flexibly install, run, and use customer-specific third-party software or, for example, their own Python-based scripts, including computationally intensive applications, provided they have the necessary rights and licenses.
