Introduction
The compact magnetic field generator and analyzer MGA 1030 allows susceptibility tests against magnetic
fields from DC up to 250 kHz according the standard EN 55103-2 (product standard for professional audio,
video and light control techniques) and there measurement according to EN 55103-1.
In combination with our tri axial Helmholtz coils full automated susceptibility tests are possible at magnetic
field strength up to 1000 A/m for frequencies from DC to 1 kHz. Lower field strength can be generated for
frequencies up to 250 kHz. Due to the tri axial set-up of our Helmholtz coil major improvement in device
handling is achieved because there is no need to turn an EUT during tests.
The MGA 1030 complies to all magnetic field requirements of relevant EMC and military standards.
More EMC tests are possible according the standards below:
- IEC / EN 61000-4-8 - SAE J 1113-2, SAE J 1113-22 - GM W 3097
- ISO 11452-8 - Ford ES-XW7T-1A278-AC - MIL-STD-461 E/F RS 101, CS101
- PSA B21 7110 - DC – 11224, DC 1014 - and similar standards
Furthermore magnetic field measurements acc. MIL-STD-461 E/F RE101, CE101 are possible
Tests and measurements are controlled by a program which will set most parameter automatically. For any
relevant standard, which are fulfilled by the MGA 1030, limit values are already included into the software
package, although any different value can be defined by a user. After every test full reports will be created
automatically. Report layout is pre-defined, though any user-defined layout is possible.
High performance is guaranteed by a self-calibration process which utilizes an internal source as reference.
Benefits
♦ Components
MGA 1030 consists of three independent module: a signal generator (DC – 250 kHz), a power amplifier
(800W output maximum, DC – 1MHz bandwidth) and spectrum analyzer (16 Bit, 1 MSPS sampling rate).
All modules can be used as stand-alone units.
♦ Software
Any function is controlled via an application which also guide the user through any test or measurement.
Adaptation of signal strength or measurement graphs are possible at any stage. User defined signals
complement the usage for fast and reliable tests. The application software is written in LabVIEW which
guarantees stable and fast performance on any Microsoft® Windows platform
♦ Additional equipment
Our company also provides many different coils and loop sensors which are ideally suited for the
described tests. Not only our own equipment can be used with the MGA 1030, but also user defined coils.
A calibration mode is included in the software to complement the magnetic test system with any further
equipment.

♦ Self-calibration
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.
Applications
♦ Automotive Testing
Intensive testing is required for new products which should be used in any automotive application. The
MGA 1030 allows fast and easy testing according to many automotive standards as described before.
♦ Magnetic Field Generation
MGA 1030 enables a user to generate strong magnetic fields up to 1000 A/m. Even alternating fields up
to 250 kHz can be generated by the magnetic test system
