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

The perfect analysis:
Professional RF measurement devices use a frequency dependant measurement approach, the so-called spectrum analysis. In a certain frequency range, the individuals signals and their respective strengths are being broken down, for example into a "bargraph" display (see SPECTRAN® screenshots on the right). The height of the individual bars represents the corresponding signal strength. For the 3 strongest signal sources, SPECTRAN® automatically displays the exact frequency and signal level, thanks to its "Auto Marker" feature. Of course, you can also setup the filter width and the frequency range to be analysed as you like.

In the RF spectrum shown, a frequency range of approx. 100MHz to 7GHz from left to right is being analysed (full sweep). During analysis, the Auto Marker feature has determined - fully automatic - three main signal sources:
Signal#1=942MHz (GSM communications) at -63dBm
Signal#2=2024MHz (UMTS) at -23dBm
Signal#3=5832MHz (802.11a WLan) at -42dBm

Thanks to its DIRECT frequency display of the individual signal sources, a doubtless mapping of measurement results to the corresponding radiation sources is possible.

The very common low cost BROADBAND MEASUREMENT DEVICES (especially common among novice users) do not give you too valuable information at all. You do receive a measurement result (for example, 500nT), but what is the frequency ? Of how many radiation sources is this result composed? What causes the radiation ? Are there multiple sources ? Is the reading maybe even composed of several signal sources ? What is the corresponding exposure limit for this reading ? What IS the exposure limit if a mixture of several frequencies is present ? Questions and yet more questions WITHOUT an answer. In contrast, using a SPECTRUM analyzer, you will ALSO consider the frequency of the signal sources, as the frequency is JUST as important as the signal strength itself. ONLY using the frequency information, a radiation source can be isolated reliably, and ONLY using the frequency, calculation of frequency-dependant exposure limits can be accomplished.
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).

LONG-TERM MEASUREMENT (Data logging feature)
For SERIOUS measurements:
SPECTRAN® measurement devices with data logger allow 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 (see attached graphics). 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 analysed. Thus, the ACTUAL total exposure can be evaluated precisely.
With this functionality, you can even discover sporadic EMC problems which would otherwise be very hard to detect.
Even though SPECTRAN® units "only" last 4 or 7 (depending on model) hours with one battery charge, the intelligent "Powerdown mode" enables much longer data logging and measurement timespans. Finally, if this is not enough, the external power supply can be used to extend the recording timespan infinitely.

Daily variation of this RF transmitter discloses EXTREME variation in time

Long-term recording with SPECTRAN® units is particularly INDISPENSIBLE with measurements of appliances and their cabling if their power output or radiation varies considerably with time. The attached screenshots show the EXTREME variations which can occur in the course of a day. This is a fact widely unknown by many users. In the worst case, measured at the "wrong" time of day, very low levels could be measured, even though the exposure, not to talk about peak exposure, might be higher by a factor of ONE HUNDRED THOUSAND (this is NOT an error) at a different time of day. Great caution needs to be taken, especially if measurement is performed as a commercial service: The very common practice of short-term measurements (being more cost-effective) often cannot evaluate the ACTUAL daily level of exposure.

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.

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).

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!).
