The Schloder compact magnetic field generator and analyzer MGA 1033 allows susceptibility tests against magnetic fields from DC to 250 kHz according the standard EN 55103-2 and there measurement according to EN 55103-1.

In addition, EMC tests are possible according to various standards such as automotive, avionic and MIL-STD. 

In combination with the coupling transformer MGA ISS-19, tests according to DO-160, Section 19 are possible or in combination with the MGA CT 50A, tests according to DO-160 Section 18 are possible.

Performance Features

The MGA 1033 contains three independent modules:
- Signal generator DC - 250 kHz
- Power amplifier max. 800 W
- Spectrum analyzer 16 Bit
All three units can also be used as "stand-alone" devices

Full automatic testing
In combination with a Triax-Helmholtz coil can be tested EUT in 3 axis without rotating the EUT. Magnetic field strenghts up to 1000 A/m at frequencies from DC to 1 kHz are possible. Smaller field strenghts can be achieved up to 250 kHz

Calibration of a Helmholtz coil
In combination with a loop sensor (RLS 133 or LS 133), the Helmholtz coil can be calibrated. It can also custom coils are used. A calibration routine in the software of the MGA 1033 allowed linking of additional test agents.

Using an ultra-stable voltage source self-calibration correction values are stored in an internal EEPROM. Any voltage signal or voltage measurement device is calibrated as a self-calibration process automatically in about a minute.

The IEC 60601-1-2 standard is the international standard for testing medical equipment to EMC.
The latest update adds a new test as more transmitter products are present in homes, offices (locations where medical equipment may be used), and hospitals.
Three frequencies that are in use are: 30 kHz, 134.2 kHz, and 13.56 MHz.
The standard IEC 61000-4-39 for testing fields in close proximity is referenced for this testing. With our IEC 60601-1-2 setup these test fields can be produced.
