Magnetic field tests per IEC 61000-4-8 and -9
The test routines for handling the magnetic field tests are included in the internal NSG firmware. All functions to
control external options as voltage/current sources or magnetic field antennas are included. In addition, the following
hardware is required:
Option required for Magnetic Field Test 50/60Hz per IEC 61000-4-8
- External transformer (VAR 3005A-S16) and magnetic field antenna (square 1 m x 1 m coil MFC 1000 or MFC
1000.1)
- External current transformer (MFT 30) with 1 turn to test 1, 3, 10 and 30 A/m levels
- External current transformer (MFT 100) with 1 turn to test 100, 300 and 1.000 A/m levels (300 and 1.000 A/m are
short-term tests of 3 sec.)
