RF Measurement in this price range has never been this PROFESSIONAL.
Find radiation sources in your surroundings. 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 euros 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). This ultra-fast processor even allows REAL-TIME display in all EMF (LF) versions of the SPECTRAN® series (could you ask for more?). Simply amazing!

Fast, handy, cost-effective, beautiful exterior and PRECISION - what more could you ask ?

Affordable PRO measurement equipment: SPECTRAN® 10xx

At the push of a button:
Exposure limit calculation used to be a complex and awkward procedure even for the professional, as most of the time, a chaotic mixture of an abundance of different frequencies, modulations and signal strengths is present.
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 bargraph display (including convergence display in percent!), while the measurement is running.
The attached SPECTRAN® screenshot demonstrates how it works: At the push of a button, the ICNIRP exposure limit has been chosen among the various available exposure limits. SPECTRAN® now automatically calculates convergence 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. A true nightmare for every processor. In our test case, the graphic display shows an approximation towards the ICNIRP limit by 6,06%. If you use a HF-6080 you can even cover the total ICNIRP-banwidth (depending on frequency). Hence, even the novice can perform exposure limit calculations ACCORDING TO STANDARDS without having to use complex tables and calculators.
It really can't get any simpler.

Frequency-dependant exposure limits demand complex calculations

Dead-easy exposure limit calculation with SPECTRAN units SPECTRAN® displays exposure limits both as percentage as well as a bargraph display. Our example shows approximation to the ICNIRP exposure limits by 6,06%. (Screenshot)

The very common low cost BROADBAND MEASUREMENT DEVICES (especially common among novice users) do not give you too valuable information at all. Due to the MISSING frequency reference with low cost broadband units, DRAMATIC misinterpretations can arise: when exposure limits are calculated, these can be wrong by MORE than a factor of 1000!! (this is NOT an error, we do really mean ONE THOUSAND).

HUGE digital LC display
Pure luxury:
The huge, high resoution digital LC display more than 80x60 mm in size! It has been developed especially for SPECTRAN® by Aaronia. Needless to say, is uses FSTN quality for crystal clear display. It covers a vast amount of display capabilities (listed from top to bottom):
  • Big graphics display (pixel display) with 51x25 pixels (can be used for complex spectrum and exposure limit display, convenient menu navigation, etc.)
  • HUGE numeric display (4 digits, max. 9999)
  • Large, high-resolution bargraph (50 segments) for very responsive trend display
  • Various function and mode indication display blocks (AUDIO, MODE, MEMORY etc.)
  • Large multi-function text display (6 text fields / e.g. for displaying units, service information, etc.)
  • Three further big numeric displays (4 digits each, each max. 9999 / e.g. for simultaneous display of MIN, MAX, AVG values, 3 marker values, etc.)
  • Triple multi-function text displays (Next to each of the previously described numeric displays / 3x3 text fields each / used e.g. for unit display for markers, etc.)
  • Three more multi-function text displays (directly beneith the previously described displays / 3x6 text fields each / e.g. ADDITIONAL values AND unit display for markers, etc.)
  • Battery status and charging display (incl. "CHARGING" and "LOW")
  • 6 numerical displays for flexible bargraph scaling (incl. multiplication factor and percentage display)
Thanks to the vast amount of flexible display options, this device can display various readings, a bargraph AND a spectral display (starting from NF-1010E resp. HF-2025E) SIMULTANEOUSLY, without bothersome switching back and forth.

Using SPECTRAN®, the user is supplied with virtually ALL information AT ONCE, without the hassle of switching back and forth. Where else can you find such luxury at a similar price ?

Lots of power: The rechargable Aaronia NiMH battery
Superlong operating time:
Starting with the SPECTRAN® HF-2025E, the rechargable Aaronia NiMH high-performance battery is supplied as standard. It has been developed specifically for the SPECTRAN® devices and is optimally suited for their requirements. Thanks to NiMH technology, the dreaded "Memory effect" is now a thing of the past, as with this power battery, maximum quality and long life have been our primary goals. 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. Still, it is astounding that even when using the standard version of the Aaronia battery (1300mAh), continuous operation of the SPECTRAN® for approx. 4 hours is possible. The special version with 2200mAh (available at an extra charge) bumps this up to a stunning 7 hours! This is certainly a new all-time record for portable, battery-supplied spectrum analyzers, or do you know a portable spectrum analyzer which even remotely provides 7 hours of continuous operation with a single battery charge ?
Naturally, the necessary battery charger is also included. At the same time, it can be used for operating the SPECTRAN® units with mains power. The battery charger is integrated into all SPECTRAN® units, thus the SPECTRAN® model HF-2025 can also subsequently be extended with an Aaronia battery (STRONGLY recommended!).
