Generators
The most comfortable test equipment to conduct magnetic field tests as per IEC 61000-4-8 and IEC 61000-4-9 is
the compact generator type
compact NX5 / compact NX7, NSG 3040A, NSG 3060A series
.
For easy testing 50Hz / 60Hz magnetic field an ac source like
NetWave
is very comfortable.
- Maximum control comfort.
The most powerful control capabilities are included in the compact NX and NSG 30x0A series generators Within
these units the magnetic field test is integrated in the device app software as well as in the user friendly
iec.control windows software.
- Alternatives
Magnetic field tests can also be conducted together with a VCS 500N surge generator (IEC 61000-4-5) and
PFS 500N series generator (IEC 61000-4-11). It is necessary to modify the DIPS or surge routines for perform
these tests.
Pulsed magnetic field
The pulsed magnetic field as per IEC 61000-4-9 will be realized by using a surge generator as per IEC 61000-
4-5. Some older generators require an additional 18 uF capacitor, that is in series with the coil antenna. Newer
surge generators have already a built in 18 uF capacitor
