INA 702
The INA 702 is a 1 x 1 m loop - 11 turns
– coil factor 9.8 - when fitted with the power plug. It enables
the generation of field strengths of up to 40 A / m for mains frequency fields 50 or 60 Hz when used
with the MFO 6501 or MFO 6502 current sources.
INA 702 becomes a single turn loop when fitted with the pulse plug, which allows the generation of
pulsed field strengths up to 1200 A / m, where the current is generated by a 4400 V surge generator.
In order to meet the pulse waveform required by IEC 61000-4-9, the waveshape adapter INA 752
needs to be used with NSG 3150 and the INA 701 and INA 702 loop antennas.
The tests are carried out using the so-called immersion method, i.e. the item under test is placed in
the center of the loop. The test is performed in accordance with the IEC 61000-4-8 (mains frequency)
or IEC 61000-4-9 (pulsed) standards for magnetic fields.
