Narda Safety Test Solutions presents the SignalShark monitoring receiver. Powerful, portable, versatile and suitable for both mobile and fixed applications, the unit combines minimal noise with high intermodulation immunity. It has been designed specifically for rapid detection and analysis, classification and localisation of RF emissions between 8 kHz and 8 GHz.

One of the most common tasks in telecommunications measurements is an examination of signal levels versus frequency. Here, users benefit from the high dynamic range (HDR) of the SignalShark — that is, its ability to capture low-level signals in the presence of higher-level signals without problems. HDR necessitates a difficult balancing act between high sensitivity for low levels and maximum insensitivity to saturation due to high levels in the direct vicinity.

Measurement engineers are often faced with the tricky situation when they need to make high-sensitivity measurements at locations close to VHF antennas or base stations in order to trace unknown interference that is present at much lower levels. The SignalShark’s preselector makes it possible for it to suppress frequency ranges that would interfere with the measurement.

The preamplifier and first mixer stage define the low intrinsic noise (displayed average noise level or DANL). The product’s good dynamic range is the result of the combination of DANL with the ‘insensitivity parameters’ — that is, the second and third order intermodulation intercept points (IP2 and IP3).
