Please read the following manual
carefully before starting up your
measurement device. The manual
gives you useful instructions how to
operate the unit correctly.

With your purchase of this SP CTRAN low-frequency measurement device, you
have bought professional equipment which allows you measuring low-frequen-
cy fields.
Please note: For measuring high-frequency fields (cellphones, mobile commu-
nication, RADAR, TV and others), you would need additionally one of our high-
frequency HF-SP CTRAN models.
Therefore we recommend purchasing one of our cost-effective measurement
BUNDL S, which you can obtain from Aaronia at any time by paying the corre-
sponding price difference.
Upgrading to a higher-grade SPECTRAN model (for example, an NF-5030
instead of the NF-1010E) is possible at any time. Likewise, OPTIONS like
memory expansions, frequency expansions or a higher-grade battery can
also be purchased and added to your unit whenever you need them.
In case of replacement, our devices are optimally recycled, including all circuitry.
In this regard, also check our warranty’s terms and conditions in the chapter
“The Aaronia warranty”.

Don’t bring ever the analyzer in contact with water. Don’t use it if it is raining. The
sensitive electronic system could otherwise be damaged.
Avoid excessively high temperatures. Do not leave the device on heating radia-
tors, in direct sunlight or in your car.
Due to the high sensitivity, the sensors and display of this device are shock-sen-
sitive, therefore it should be handled with care. Don’t let the device or antennas,
falling down as they could be damaged or destroyed!
Consequently, we strongly recommend to usw our special transport case
for storage and transportation. It is also available as a very durable versi-
on made of special plastics (available at an extra charge).
ven though all SP CTRAN models are pretty safe due to their counter-sunk
screws, they should not be kept in the reach of children, as they might be a
potential threat in this case!
Your measurement device is maintenance-free. Only clean it outside with a
damp cloth. Do not use any cleaning supplies.
ATTENTION:
Always screw antennas and adapters always in a non-violent way. Please
use for loosening or screwing of SMA connections ONLY the enclosed
SMA tool, which offers an over-tightening protection.

To explain the use of SPECTRAN, we will measure its own power supply.
During this procedure, you will get to know the 3 different operation modes
of SPECTRAN, as well as the important OLD feature and the panning
approach:
It is really very simple, just follow the following instruction step by step:
ow to prepare SPECTRAN for measurement:
Remove the protective film from the display. Should
you not yet have charged the integrated battery, you
can also operate SP CTRAN with the included
power supply (further information on page 51).
Next, press the on/off switch located in the
lower left corner.
SP CTRAN is now switched on and will perform a
brief calibration procedure.
For easier orientation, we will now briefly show the most important aspects of the
SP CTRAN display:
Now we’re ready for making measurements of SP CTRAN’s own power supp-
ly. First, plug the power supply into a power socket. Now, you can measure the
magnetic field of the power supply as follows:
5.0 Your first measurement / Modes
Firmware V 1.0 / © 2005-2013 by Aaronia AG, D-54597 uscheid, www.aaronia.com 9
BARGRAP (trend display when Reflev is not in Auto-mode)
Depending on signal strength, the half-circle will grow or shrink. A very
handy function for quickly changing levels!
INFO display
Displays the current physical unit and various menu information.
MAIN display
Displays signal strength or voltage in T, G, V/m, A/m or V.
MARKER block (1 to 3)
Displays frequency and signal level or voltage of the strongest signals.
Up to three markers can be displayed simultaneously.
GRAP ICS display (here: spectrum display)
This highly versatile display field can provide a multitude of textual and
graphical information (spectrum or exposure limit display, menus).
DISPLAY MODE status field
Displays the current operation mode of SP CTRAN. Possible values
are: SP CTRUM (spectrum analysis), XPOS.-LIMITS (exposure
limits) and AM / FM (audio output).
MODE status field (MinMax and OLD)
Displays the detector and mode which is used. Possible values are:
MIN MAX and HOLD (advanced HOLD mode).

Switch on the unit and press key 2. That’s all you have
to do. Now, the most “popular“ measurement will be
carried out:
The frequency range between 45 and 65 z is measured
(sweeped) now. The large main display shows the
strength of the magnetic field in Tesla (T), the so-called
readout. Above the readout on the main display, the phy-
sical unit is shown. Depending on field strength, it will
automatically switch between (for example) µT and mT
(autorange feature). If you approach the power supply,
the field strength will increase, likewise, it will rapidly
decrease when you move further away.
It might be necessary to set the correct mode of operati-
on by using the nter key. Push it repeatedly until the dis-
play mode status field reads “SPECTRUM”.
Of course, SP CTRAN is far more capable than this, so following is a more
detailed introduction about how to use further features:
5.1 Choosing the sensor [Key 6]:
In general, you should know that there are two different
kinds of fields that are measurable with SP CTRAN in
the proximity of electrical appliances and installations:
electric alternating fields and magnetic alternating fields.
For each of these field types, you need an appropriate
sensor. Both sensors are already integrated into our
SP CTRAN devices. The appropriate sensor can be cho-
sen at any time using the key 6 (use the up/down
arrow keys to choose, and apply your selection with
the nter key).
For magnetic fields, you need the Mag sensor. Press the
key 6 and select the Mag sensor (further options are XY-
Mag, YZ-Mag and ZX-Mag).
If you want to measure electric fields, press the key 6
and select the E-Fld sensor. Please note that measure-
ment of electric fields can be easily interfered. Please
have a closer look at the “Measurement of electric fields”
section for more information.

Using our Option 006, which can be retrofitted as an upgrade at any time,
you can also measure STATIC magnetic fields, like the geomagnetic field (geo-
logical dislocation) or the strength of magnets (for example in loudspeakers). To
do this, just press key 6and select the MSta sensor (possible choices are X-
MSta, Y-MSta and Z-MSta).
If you have an NF-3020 or better, you can also select the external input (SMA
socket), which allows you to connect arbitrary external sensors like large, high-
ly sensitive coils, testing probes, or other special antennas. You could also sim-
ply measure a voltage. This input provides you with a whole range of new pos-
sible applications and converts SP CTRAN into a versatile all-rounder. For
using the external input, press the key 6 and choose Analog.
5.2 Choosing the mode of operation [Enter key]:
All SP CTRAN models offer 3 different MODES OF OPERATION:
- SPECTRUM analysis (graphical display of signal levels and frequencies)
- EXPOSURE LIMIT display (percentage of a particular exposure limit)
- AUDIO output (makes modulated signals audible)
You can switch between the different modes of operation at any time by
using the Enter key.
5.3 Mode Spectrum analysis:
(The DISPLAY MOD status field displays “SP CTRUM”)
Press the Enter key until the display mode status field
reads “SPECTRUM”. SP CTRAN will now provide a rea-
dout similar to the one shown in the picture on the left.
Should the large main display show “0000“, then no
signal is found. In this case, you probably have to mea-
sure closer to the signal source. During every measure-
ment, a small dot will constantly move from the left to the
right edge of the upper part of the graphics display.
Only when this point reaches the right edge, the mea-
surement is completed and all readout values are
updated, very often it will be so fast that you won’t
even notice.
The main display shows the current field strength, in our example it is 45,15µT.
5.0 Your first measurement / Modes
Firmware V 1.0 / © 2005-2013 by Aaronia AG, D-54597 uscheid, www.aaronia.com 11

Directly below up to 3 so-called “markers” are displayed. These show the fre-
quency and corresponding signal strength of the strongest signal sources. In our
example, we have two markers. Marker1at 30Hz and 45µT and marker2at
50Hz and 75µT (75µT is at the same time the strongest signal overall, that’s why
it is also displayed on the main display).
Below the markers, the graphics display shows a graphic consisting of a num-
ber of little “hills“. This graphic is called “SPECTRUM DISPLAY“. The higher the
“hills“, the stronger the corresponding signal. The markers mentioned previous-
ly show the frequency and level at the peaks of each “hill“.
Using frequency charts, it is also possible to make assumptions on the origin or
source of the corresponding signal. See our frequency charts on page 56 for
more details. Please note that marker-frequencys are always shown with one
decimal place.
5.4 OLD mode
(The MOD status field displays “HOLD”)
As you have probably already noticed, the display chan-
ges constantly. This is completely normal as the field
strength also changes with distance to the signal sour-
ce. Simply try it out yourself - move the device around the
signal source and keep an eye on the display and the
changing readouts.
Often, the user just wants to check the highest possible
readout. However, as the display always keeps chan-
ging, this might cause difficulties. To solve these pro-
blems you can use the so-called OLD mode. To activa-
te it, press the dot key. The mode status field will display
“HOLD”. From now on, only the strongest measured sig-
nal will be displayed. Furthermore, the spectrum display
will not be erased - it seems to literally “freeze“. By pres-
sing the dot key a second time, “HOLD“ will disappear
from the MOD status field and HOLD mode is turned off.

5.5 The panning approach
When evaluating exposure limits, usually only the maximum signal level is
important. This maximum can be determined by using the so-called “panning
approach“, which is already established as a legally binding means of measu-
rement in many countries. Proceed as follows:
Choose the desired frequency range. In our example, we have already done so
(key 2). Activate HOLD mode (dot key) as described previously. Afterwards plea-
se also activate 3D measurement by pressing the 8 key. This will save you the
hassle of having to move the device around constantly in all directions near the
measurement subject.
Now, keep measuring until the value stops changing completely. You have now
determined the signal maximum at a particular position/location.
However, should you wish to determine the signal maximum in an entire room,
you additionally need to measure at every possible position. Walk through the
entire room, pay special attention to the walls and electrical appliances, where
you will often find the strongest signals due to electrical wiring. During measu-
rement, the displayed signal strength will rapidly increase, until at some point it
will stop changing and “freeze“ at the signal maximum. This can take several
minutes when testing an entire room. After completion of this procedure, the
maximum signal strength found in the entire room is shown on the display.
As field strength diminishes very rapidly with increasing distance (depending on
the source, r, r² or even r³), you can quite easily determine the exact location of
a signal source (the higher the signal level, the closer the source). Of course,
you will need to turn off HOLD mode in this case. Next, simply try to find the sig-
nal maximum in various rooms to get acquainted with the panning approach and
the importance of HOLD mode.
Now, of course your measurement result is not that useful if you cannot relate it
to any exposure limits. Until today this used to be very complex with the need to
browse complex tables and convert between physical units. A highly daunting
task for the novice and even for some experts. SP CTRAN offers therefore a
special and easy to handle mode for exposure limit calculation:
5.0 Your first measurement / Modes
Firmware V 1.0 / © 2005-2013 by Aaronia AG, D-54597 uscheid, www.aaronia.com 13

5.6 Exposure limits mode
(The DISPLAY MOD status field displays “ XPOS.-LIMITS”)
Press the Enter key until the display mode status
field shows “EXPOS.-LIMITS“.
As usual, the strongest signals will be shown along with
their frequencies and levels as markers, as in the spec-
trum analysis mode. The large main display will again
show the level of the strongest signal found.
However, in the graphics display below, the strongest sig-
nal will be shown now as a percentage in relation to an
exposure limit: As various very different exposure limits
and recommendations are existing for the various fields
of interest and professional groups, SP CTRAN offers an
entire range of different exposure limits. You can select the desired
exposure limit by using the right/left cursor keys. Find a more detai-
led introduction to these exposure limits on pages 47 and following in this
manual.
Please try it yourself: Select all the different exposure limits and compare the
results. The available exposure limits are:
xTESLA = Shows the readout in Tesla
ICNIRP = ICNIRP recommendation also German limit (General population)
BGRB11 = BGF limit for workplace exposition (exposition class 2)
BImSch = 26. BimSchV (Indutrial German limit) (only 16,66Hz, 50Hz, >10MHz)
TCO99 = International limit for computer screens (only from 5Hz-400kHz)
In our fictional example, the exposure limit bargraph shows an approximation to
the German ICNIRP limit of 69%. When XC DING the exposure limit, the dis-
play will show percentages above 100% (for example, 128,00 = limit exceeded
by 28%). When exceeding the exposure limit by more than 999.99%, the display
will show “***.**”, indicating overflow.

INT: You will always find current or updated exposure limits on the Aaronia
homepage for downloading, e. g. when legal changes occur and official limits are
altered This allows you to keep your SP CTRAN always updated. We also
recommend our free PC analysis software, which offers a lots of additional fea-
tures.
Another approach to precisely locate a signal or determine its origin is demodu-
lation. This feature allows you to hear potential pulsing or modulation of a signal
source. As with other features, SP CTRAN has a special mode for this kind of
operation:
5.0 Your first measurement / Modes
Firmware V 1.0 / © 2005-2013 by Aaronia AG, D-54597 uscheid, www.aaronia.com 15

5.7 Audio output mode (demodulator)
(the DISPLAY MOD status field displays “AM” or “FM”)
All SP CTRAN models offer a so-called demodulator.
This demodulator turns pulsings and modulation of signal
sources into tones.
Frequency-accurate and selective acoustic representati-
on of a signal can be helpful with identification and locati-
on of a signal source. As demodulation occurs in realtime,
it is suited perfectly to find the signal source very quickly.
SP CTRAN offers two different demodulation modes:
AM (amplitude modulation “AM”)
FM (frequency modulation “FM”).
You can switch between the demodulation modes by
pressing the dot key (the DISPLAY MOD status field
displays “ “AM” or “FM”).
You can adjust the volume by turning the volume knob on
the left side.
ATTENTION: During audio analysis, the entire display
will be “frozen“ and the pixel field is turned off com-
pletely to save computing power for demodulation.
Then ONLY acoustic reproduction of the signal is car-
ried out!
In contrast to simple broadband detectors, SP CTRAN
performs its demodulation only at a specific frequency (center frequency). Thus,
you can selectively „listen“ small individual frequency ranges. However, please
note that filtering in this mode is slightly less stringent. As a result, strong signals
on neighbouring frequencies might “bleed“ onto the actual selected frequency
and be audible as well.
For optimal audio reproduction of signals, you can choose between several fil-
ter bandwidths by using the up/down arrow keys. The currently selected filter
will be shown in the large INFO display.
Display is ”frozen“
Pixel display is turned off

Firmware V 1.0 / © 2005-2013 by Aaronia AG, D-54597 uscheid, www.aaronia.com
16

You will often find that it is difficult to accurately find the right center frequency
and demodulation is bad or not successful at all. Hence, by pressing the
right/left arrow keys, you can fine-adjust the center frequency. The used
step width is based on the filter you have previously selected. For example,
should you have chosen a 1kHz filter, fine-adjustment will take place in steps of
1kHz, and so on. The new center frequency will be shown on the large INFO dis-
play after changes.
ATTENTION: For optimal audio reproduction of signals, their levels should be
significantly higher than the noise floor.

So far, our examples were only using the provided frequency presets available
at key 2 (45-65Hz). However, you can also make a manual, highly precise fre-
quency range (sweep) adjustment:
Recall frequency range presets
At the keys 1 - 5 are different presets available including
the optimal frequency selection for traction power
(16.7Hz), mains power (50Hz/60Hz), harmonics, TFTs,
switching power supplies and others.
Usually these are the measurements which almost any-
body wants to carry out. The amateur in particular will
appreciate these presets, as all frequency parameter are
already adjusted.
However, you can also make a manual, highly precise frequency range (sweep)
adjustment. This way, you can set a frequency range exactly tailored for a spe-
cific signal source in order to measure only this single source.
To set the frequency range, you simply need to know the start and stop fre-
quencies of the subject to be measured and provide them to SP CTRAN. You
can find an excerpt from the start and stop frequencies of various signal
sources in the frequency table on page 56.
Manual adjustment
There are two ways for setting up the requested frequen-
cy range exactly. You can either go in the menu to the
Start and Stop frequency, or just work with the Center
frequency.
In the following paragraphs, you will find an explanation of such a manual mea-
surement, using a TV set or computer monitor as an example. Proceed as fol-
lows:
First of all, have a look at the frequency list on page 56. From this list, you can
derive that TV sets or computer monitors work in the frequency range from
approx. 31kHz to 56kHz. We choose a slightly more liberal frequency range of
20kHz to 70kHz. These are the searched start and stop frequencies which you
have to set as follows:

1.) Please choose in the menu fLOW to enter the START frequency
A suffix-list will be displayed then. Please use the arrows keys to select
k z. Confirm your selection by pressing the nter key.
The large main display will now show zero. In addition, the large status field will
display START. Now by using the number keys, enter the START frequency in
kHz, in our example, 20kHz. Hence, enter 20 (you can correct typing errors by
using the CLR key and entering the number again). Press then the nter key
once again to confirm your entry.
Leave the the entry by pressing the menu key and you are back in the main
menu.
2.) Please choose in the menu f igh to enter the STOP frequency
Again, the suffix-list with z, k z, M z etc. will appear. Choose k z once
again. Press the nter key to confirm your selection.
