Aaronia Spectran V3 [HF 4040]Handheld RF Spectrum Analyzer 100 MHz - 4 GHz

The Aaronia Spectran HF-4040 100MHz to 4GHz Handheld Spectrum Analyzer is used measurement of electric and magnetic fields while making it easy to use and understand. Find radiation sources in your surroundings with the HF4040, as well as find their respective frequencies and signal strengths, including direct display of exposure limits. This used to be impossible in this price category, professional units often costing several thousand dollars and being excessively complicated in handling. The highly complex calculations in spectrum analysis incl. exposure limit calculation is being performed, unnoticed in the background, by a high-performance DSP (digital signal processor).

Professional EMF measurement devices often use a frequency dependant measurement spectrum analysis. In a certain frequency range, the individuals signals and their respective strengths are being broken down, for example into a "bar graph" display. The height of the individual bars represents the corresponding signal strength. For the 3 strongest signal sources, the Spectrum HF-4040 can automatically displays the frequency and signal level, thanks to its "Auto Marker" feature. The user can also setup the filter width and the frequency range to be analyzed.

The Aaronia Spectran HF4040 allows long-term recordings of measurement results over a freely adjustable period of time. This is particularly indispensable for serious evaluation of exposure by appliances and machinery which have a changing power consumption or radiation strength over time. Examples for these include railroads, power lines and plants, but also home appliances and their respective power cables, and various high-frequency transmission facilities like mobile phone transmission towers, mobile phones, radar etc. Depending on the time of day, considerable variation of exposure can occur. Without long-term recordings, massive misinterpretation of total exposure can occur. With long-term data logging using SPECTRAN, the daily variation of exposure can be recorded and analyzed. With this functionality, the user can even discover sporadic EMC problems which would otherwise be very hard to detect.

The Aaronia NiMH high-performance battery has been developed specifically for the Aaronia spectrum spectrum HF:4040 device and is optimally suited for their requirements. Thanks to NiMH technology, the dreaded "Memory effect" is now a thing of the past; maximum quality and long life have been Aaronia's primary goals when it comes to their line of products. Another reason why such a battery technology is necessary is the high power demand of the high-performance DSP used in all Spectran units, especially in the RF versions, which furthermore include very demanding RF receiving circuitry.

Exposure limit calculation used to be a complex and awkward procedure due to a chaotic mixture of an abundance of different frequencies, modulations and signal strengths listed.

The indispensible, highly complex calculation of frequency-dependant exposure limits can only be performed conforming to standards by a spectrum analyzer with high-performance software. Not a problem for SPECTRAN units: They can calculate even several authoritative exposure limits, precautionary limits and recommendations (simply selectable via a button) and display these as a practical bar graph display or convergence percentage display, while the measurement is running.

At the push of a button, the ICNIRP exposure limit has been chosen among the various available exposure limits. The Aaronia Spectran HF-4040 automatically calculates convergence or excess of this limit. For achieving this, often thousands of complex calculations have to be performed per second, and a steady scan of the entire frequency range needs to be performed.

When the comes to the attachable Antenna, Aaronia offers a very cost-effective alternative with the Aaronia HyperLOG® 7040 with the Spectrum HF-4040, still meeting even the highest expectations. The HyperLOG HF-7040 offer an exceptional mix of performance, functionality and design formerly unknown in this price category. Together with the HyperLOG antennas, any regular spectrum analyzer instantly becomes a professional RF measurement device with directional characteristics. Due to its small weight and the multi-functional handle, these antennas are the optimal supplement for portable EMC measurement devices for locating and evaluating any kind of signal source.

Due to their flexibility in polarization, Aaronia HyperLOG antennas can also be used as handy WLAN or Wifi antennas. Point-to-point WLan links or networks can be constructed easily using the full bandwidth up to 6GHz, achieving high throughput. Optimal for MMDS, ISM, CCTV and data/telephony transmission.

Aaronia's HyperLOG 7040 come standard with a specially constructed, high tech Radom housing. This housing has been constructed after intense research with the most modern computer technology in such a way that its shape, material and special coating have virtually no influence on measurements, not even in case of dew or other kinds of humidity collecting on the surface. Another important factor for Aaronia was the development of a Radom with the lowest possible damping factor achievable. The resulting antenna had the best possible protection against mechanical stress and environmental influence without sacrificing any of its performance.

A further distinctive feature of the HyperLOG's Radom is the integrated 5/8" screw thread for accepting the included (directional measuring) handle. As it conforms to the standard due to its size of 5/8", the antenna could also be mounted to any other suitable tripod. Hence, polarization and bearing of the antenna can be adjusted optimally and reliably.

Inside the Radom, the user can find a sophisticated antenna itself, covered with a highly conductive gold coating. This high-grade coating and the antenna's special design warrant excellent linearity over the entire frequency range, and an exceptional receiving or transmitting performance. Each antenna is calibrated precisely in the Aaronia laboratories before dispatch. It is even possible to permanently store calibration data in a special IC on the antenna. These can later be recalled for dynamic antenna adjustment, for example, with an Aaronia spectrum analyzer.
