Connectors
3.1. Battery / Power supply
All MagnoTRACKER antennas are by default equipped with an internal 25dB
preamplifier.
These internal preamplifiers come with LiPo-Battery which has 3 – 4 hours
runtime.
The charging time for the LiPo-Battery is about 90 minutes. The Charge-LED
will turn red in the beginning of charging. When charging is completed, the
Charge-LED turns off.
When the antenna is turned on, the ON/OFF LED lights red. By pressing the
ON/OFF switch, you can turn on and off the antenna.
For a continuous operation, the included power supply can be used.
Frequency-Selection
The Selection can be done by choosing four control dials which cover four
different scopes respectively:
x1; x10; x100; x1000
A fine-adjustment can be done by the big control dial (0-15).
The frequency selection of this antenna is very accurate, so that the
disturbing and „uninteresting“ signals will be reduced very efficiently. The
antenna has a SMA connector as output with 50 Ohm impedance. You can simply
connect the antenna to your receiver, spectrum analyzer, oscilloscope, power
meter, etc.
Attention: The MagnoTRACKER ELF Models (ELF-2 und ELF-6) do not offer any
kind of frequency selection!
These antennas are usable over the full frequency range from 1Hz to 9kHz
without selection.
4.1. Control dials x1 to x1000 and Big control dial (0-15)
With the control dials the center frequency can be adjusted. Turn left for
high frequency. The more you turn right, the lower the frequency will get
(tuning more finely with Big control dial in the middle). For better
understanding of the functionality, it is recommended to connect the antenna
to a spectrum analyzer and start a quick sweep with 9 kHz to 1MHz Span. Then
you will understand more clear on the operation modes of the antenna.
4.2. Slide switches 1 to 4
With 2 Slide switches (1-4) the antenna can be adjusted to 4 different
internal antennas (here both Slide switches must always have the same
position). The higher frequency you want, the smaller setting you should
choose. (1= high frequency, 4= low frequency, see page 11).
Application Example
The MagnoTRACKER is a magnetic field antenna. The antenna is not suitable for
measurements of electric fields.
One of the typical application areas of the MagnoTRACKER is the detection of
disturbing signals (e.g. on telecom wires like DSL, ADSL, etc.), which are
generated e.g. from switching power supplies. Further typical application
areas would be amateur radio, reception from submarine communication, maritime
radio, Sferics and RFID appliance.
The possibility to fine-adjust the antenna offers a directivity/resolution of
up to 1 degree or even better.
First measurement
Example: Time Signal Transmitter DCF77
Let’s say we measure a long-wave transmitter in Mainhausen (Germany), which
provide standard time for most of the radio-controlled clocks in western
Europe. The transmitter works at frequency 77,5 kHz with 50 kW power and it is
possible to measure with the MagnoTRACKER and a proper instrument / Spectrum
analyzer (e.g. SPECTRAN NF-5030) within Germany and a big part of neighboring
countries.
Frequency setting 77,5 kHz
| Slide switch (X and Y) | both set at 1 |
|---|---|
| Control dial x1 | set at 0 |
| Control dial x10 | set at 0 |
| Control dial x100 | set at 6 |
| Control dial x1000 | set at 4 |
With correct signal reception, you should be able to see the amplitude changes of the DCF77 Signals without any problems (Signal strength changes in constant rhythm).
6.1. Direction finding
Locating the signals can be achieved by turning the antenna around very
slowly. The most effective way of signal direction finding can be managed by
means of the Minimum-Method.
To do so place the antenna exactly 90° to signal source and then it will have
the lowest sensitivity (see picture below). This method is generally the best
and the easiest way in
practice to quickly detect a signal, instead of time consuming search for the
signal maximum.
Recommended Settings
You can find a recommended selection of settings depending on the measuring frequency in the following table.
Frequency| Slide switch X & Y| Control dial x1| Control dial
x10| Control dial x100| Control dial x1000
---|---|---|---|---|---
10kHz| 4| 0| 0| 3| 5
20kHz| 4| 0| 5| 3| 1
30kHz| 3| 0| 0| 2| 2
40kHz| 3| 0| 2| 2| 1
50kHz| 2| 0| 4| 9| 2
60kHz| 2| 2| 2| 0| 2
100kHz| 2| 0| 2| 7| 0
500kHz| 1| 7| 9| 0| 0
1MHz| 1| 0| 0| 0| 0
In general, it is possible to set various frequency adjustments and different
positions for the Slide switches (see point 4.2.). The data in this table are
just recommendations for orientation.
The most neutral and wide-band setting for LF-2 and LF-6 antennas can be
achieved by setting all the Control dial at postion 0 and both Slide switches
at position 1. This setting is recommended for measuring signals with unknown
frequency and signals higher than 500kHz.
Below graphic shows the typical resonance characteristics of the internal antennas (particularly determined by the position of the Slide switches) of the MagnoTRACKER LF-2 and LF-6 antennas:
