Aaronia HF 2025E Spectran V3 Handheld RF Spectrum Analyzer 700 MHz - 2.5 GHz

The Aaronia Spectran HF-2025E 700MHz to 2,5GHz 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 HF2025E, 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-2025E 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 HF2025E 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 2025E 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 2025E 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.
