Tektronix Communications has launched the H600 RFHawk, its handheld, digital RF signal hunter solution for the surveillance and security market. The H600 RFHawk combines a high performance spectrum analyser with an intuitive set of user controls, allowing for the quick and simple classification and location of both analogue and digital RF transmissions. Utilising the H600 RFHawk, surveillance engineers and field operators can quickly and effectively spot and locate illegitimate analogue and digital RF transmission sources in the field. The battery operated, rugged solution provides signal hunting, mapping and documentation tools and offers high performance for rapid targeting of illegitimate signals.
The touch-screen user interface offered by the H600 RFHawk is designed for field conditions and optimised for scanning the RF environment, classifying the known signals and locating the unknown or illegitimate analogue and digital RF transmission sources. The spectrogram mode feature of the H600 RFHawk allows customers to see the true signal shape through FFT-based spectrum analysis capabilities. This is useful for bursty signals such as WiFi, hopping such as GSM, or intentionally sporadic signals. The H600 RFHawk allows logging of these signals and storing geographic reference data per measurement.
A simple but powerful user interface allows for a specific region of interest to be clearly defined and isolated for scanning, analysing, and storing. Within that region of interest, the RFHawk uses a DSP technique - spectral correlation analysis - to look at internal frequencies within the signal. By using this technique, it is possible to find a digital signal's symbol rate, other repetitive internal rates and compare the signal to known valid signal types.
When an unrecognised signal is defined as a potential threat, the H600 RFHawk provides a set of signal hunting tools. Directional antenna and signal strength readings linked to built-in GPS referenced or in-building maps enable rapid narrowing of the search area, leading to the target. Users can easily plot the direction from which a suspicious signal is emanating. High sensitivity and low noise floor allow better tracking of faint signals. Increased portability and rugged features are offered by the handheld H600 RFHawk. RFHawk complement Tektronix' real-time spectrum analysis solutions.
