Cable to the magnetic field antenna
According to the standard the cable between the magnetic field generator (Transformer) and Antenna should be
- Twisted
- Max. 2 m as per IEC 61000-4-8
- Max. 3 m as per IEC 61000-4-9
The delivered 2.5 mm
2
cables have a length of 2 m 5% and must be prepared for the magnetic field test.
The user must twist or weave the four wires to a cable that has a total length of less than 2.0 m
This arrangement with a twisted cable has the following advantages:
- the cable radiates less, because the field is compensated
- The inductance of the cable loop is less
- Better handling because only one cable is there for the setup
