Overview
Electronic devices containing components sensitive to magnetic fields need to be tested for immunity to electromagnetic fields. Product standards define the applicability of such tests and specify the field strength. The basic standard IEC/EN 61000-4-8 describes the test methods for magnetic fields with powerline frequencies.
The MFO 6501 provides - together with a magnetic field antenna INA 702 or INA 701 - a stand alone test solution to IEC/EN 61000-4-8 and all the derived product standards. No additional hardware is required (except, maybe, a classical multimeter or ammeter).
| Parameter | Value |
|---|---|
| With magnetic antenna loop INA 701 | Field strength, low range: 0.08 to 0.4 A/m (80 to 400 mA drive current) |
| With magnetic antenna loop INA 702 | Field strength, low range: 0.8 to 4 A/m (80 to 400 mA drive current) |
| Total harmonic distortion (THD) | <8% for levels 1 to 4, <3.5% at max. output |
| Test frequency | Selectable 50 Hz and 60 Hz ±3% |
| Magnetic field adjustment | Manually, by rotary button |
