The Schwarzbeck´s Mess-Elektronik MagTest software can be used to perform magnetic field immunity tests according to several standards, such as, for example: MIL-STD-461G, ISO 11452-8, DIN EN 61000-4-8 and many others. The MagTest software can control the hardware to produce a magnetic field with defined field strength. Automatic and stepwise work routines are possible. The software can also be used for the calibration of monitoring loops and for scientific applications.

The MagTest software offers the following features:

  • Integration of different hardware components like Helmholtz coils, radiating loops, monitoring loops, RMS voltmeters and function generators. The measuring system can be flexibly configured;
  • Possibility to define limits freely. The unit of the magnetic field strength can be handled in “dBuA/m”, “dBpT” and “A/m”;
  • Use of INES, National Instruments, Agilent GPIB interfaces for the communication with RMS voltmeters and function generators;
  • Magnetic field curves can be shown, saved, and loaded;
  • Test requirements can easily be adapted by setting start and stop frequency, frequency steps, the offset of the magnetic field strength, the maximal error of magnetic field strength, the value of shunts, and timing values;
  • Scalable print output;
  • Possibility to design test protocols with individual comments;
  • Possibility of the manual control of RMS voltmeters and function generators;
  • Possibility to compare two different magnetic field curves.

For the use of the software the following equipment is required:

  • PC with IEEE 488 (GPIB) interface with Windows operating system (for example Windows 98, Windows XP, Windows 7, Windows 10, and Windows 11 are supported);
  • GPIB interfaces of National Instruments, INES, Agilent-VISA are supported by the MagTest software. Other manufacturers can be supported on request;
  • Helmholtz coil or radiating loop for the generation of magnetic fields;
  • Shunt resistor with e.g. 0.5 Ω/0.5 kW for indirect measurement of the magnetic field strength and for better impedance matching;
  • Monitoring loop (optional) for direct measurement of the magnetic field strength;
  • Function generator with an IEEE 488 interface for the generation of the signal for the Helmholtz coil or the radiating loop;
  • Two RMS voltmeters or a dual channel RMS voltmeter with an IEEE 488 interface;
  • Amplifier;
  • Laboratory cables.
