I. Specification of MGA 1033 transmitter and magnetic field analyzer

  • MGA 1033 Magnetic Field Transmitter and Analyzer according to product standard EN 55103, part 1 and part 2. In addition, EMC tests can be performed to various standards such as automotive, MIL-STD and Avionic. Thanks to the built-in high-performance amplifier, the MGA 1033 Schlöder magnetic field analyzer and transmitter can easily achieve high field strengths in a variety of military and automotive standards. In combination with the three-axis Helmholtz coil MGA_HCST_50/28, a field strength of 1000 A/m can be generated in the frequency range from DC to 1 kHz. Extremely convenient testing: thanks to the three-axis structure, fields are generated completely automatically in all three spatial axes - the test subject no longer has to rotate.
  • MGA 1033 consists of three main modules:
    • Signal generator (DC - 250 kHz)
    • Power Amplifier (output power 800 W, DC Bandwidth - 1 MHz)
    • Spectrum Analyzer (16 bit sampling rate, 1 MS/s)
  • All modules can be used as individual devices. Although originally developed to measure and generate magnetic fields, the MGA 1033 offers a multitude of possible uses for measurements and inspections..

II. Design

  • The MGA 1033 Schlöder Magnetic Field Generator contains 3 independent modules:
    • DC signal generator - 250 kHz
    • Maximum power amplifier. 800W
    • 16 bit spectrum analyzer
  • All 3 units can also be used as "standalone" devices.

III. MGA 1033 magnetic field transmitter and analyzer - Fully automated tests

  • In combination with the Triax - Helmholtz coil, test objects can be tested in 3 axes without rotating the test object. Magnetic field strength can be increased up to 1000 A/m at frequencies from DC to 1 kHz. Smaller field strengths can be realized up to 250 kHz.

IV. Calibration

Calibration of Helmholtz coil:

  • In combination with the sensor coil (RLS 133 or LS 133), the Helmholtz coil can be calibrated. Custom spools can also be used. Calibration mode in the software of the MGA 1033 allows the connection of additional test devices.


  • The highly stable voltage source of the MGA 1033 Schlöder  generator and magnetic field analyzer allows self-calibration, whereby correction values are stored in the internal EEPROM. All relevant instrumentation units are included in the self-calibration, the automatic process taking about a minute.
    • Includes modules: signal generator (DC - 250 kHz), power amplifier (output power 800 W, bandwidth DC - 1 MHz) and spectrum analyzer (16 bit sampling rate) , 1 MS/s)
    • Tested with magnetic field requirements for the following standards: ISO 11452-8, MIL-STD-461, IEC/EN 55103-1/2, IEC/EN 61000-4-8, SAE J1113-2, SAE J1113-22, Ford ES-XW7T -1A278-AC, GM W3097, PSA B217110, Renault 36-00-808, DC-11224, DC-10614 and similar standards.
    • Measurements and tests according to the following standards are additionally implemented in the application software: MIL-STD-461 (CE101, CS101, CS109), EN 61000-4-16 and IEC/EN 61543
    • Application software for Microsoft Windows with preset parameters/limit values, can apply own routines, data transfer from external multimeter over serial port
    • Huge range of accessories: coils, adapters, coupling devices.
