The lab in your hand. If you need to quickly detect and reliably localize hidden, sporadic or brief interference signals on the move within the more and more tightly packed frequency bands, you need the SignalShark. This device, with its handy format, is capable of dealing with today’s complex measurement and analysis tasks reliably and quickly to the same standard as laboratory instruments.

The continuous real time persistence view of the SignalShark shows every change in a signal with pixel accuracy. Even hidden signals can be detected with this. 100% POI signals › 3.125 μs

The 40 MHz real time measurement allows gapless, reliable detection of the smallest changes in the RF spectrum with the aid of the spectrogram view.

The slightest “touch” on a preset trigger mask causes the SignalShark to record the corresponding signal. A scan rate of up to 40 GHz/s ensures rapid detection, even with very wide frequency bands. 

SignalShark can also easily detect very weak signals, thanks to its high dynamic range (HDR). The combination of high sensitivity and a wide, intermodulation-free dynamic range makes this possible. DANL (pre-amplifier off / on): - 160 dBm/Hz / -167 dBm/Hz

Signal Analyzer for Detection, Analysis, Classification and Localization of RF Signals between 8 kHz and 8 GHz. Applicable for mobile and stationary use. It supports Narda directional and full automatic direction finding antennas.

  • Extremely high Sweep Rate of up to 40 GHz/s
  • 40 MHz Real-Time instantaneous bandwidth

Operating time 3 hours (nominal), battery pack is hot swappable
Dimensions 231 mm × 333 mm ×85 mm
Weight 3,8 kg (basic unit including battery)
Operating conditions -10° to +55°
Frequency range 8 kHz to 8 GHz
Real-Time instantaneous bandwidth 40 MHz
Sweep Rate up to 40 GHz/s (RBW @ 100 kHz)
  • The handle is ergonomically shaped and fits snugly in the hand, and yet it is a technically sophisticated device with several function. It accepts antennas in horizontal and vertical positions, contains a switchable preamplifier, a compass, position sensors, and a measurement start / stop button. The antenna handle communicates with the basic unit through a control cable.

  • Antenna 1 covers the frequency range from 20 MHz to 250 MHz. It therefore includes the ISM band at 27 MHz, and is particularly suitable for interference and spurious signal searching in the VHF broadcast radio range, but also covers the lower end of VHF television and includes DAB frequencies.

  • Antenna 2 covers the frequency range from 200 MHz to 500 MHz, making it eminently suitable for interference and spurious signal searches on all communications services within this band, and also includes the 433 MHZ ISM frequency.

  • The 400 MHz to 6 GHz frequency range of Antenna 3 covers the entire spectrum of mobile communications including LTE and WLAN, and also includes L, S, and C band radar, for example.

  • This low-frequency loop antenna is particularly suitable for detecting defective or poorly screened switched power supplies or electrical controllers that emit interference, and for identifying interference due to power line carrier systems, or demonstrating interference with other signals in the very low frequency range (ultra long wave).

  • Suitable accessories for applications that involve operation in vehicles or outdoors.

  • Antenna set for the frequency range from 400 MHz to 8 GHz (e.g. cellular radio signals)
