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 Teseq MFO 6502 is an auxiliary device for the NSG 3040 series and provides fully automatic power line magnetic field tests. It is connected via system cable to the NSG 3040 and is fully embedded in the configuration management, the software control and the report mechanism.
| 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 and 60 Hz ±3% |
| Magnetic field adjustment | Software driven |
