The MTS-800 is a compact test system for broadband generation and measurement of magnetic fields. Its internal components allow automatic EMC tests according to automotive standards where high field strength need to be generated or measured.
In combination with our triaxial 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 triaxial setup of our Helmholtz coil major improvement in device handling is achieved because there is no need to turn an EUT during tests.
Tests and measurements are controlled by a program which will set most parameter automatically. For any relevant standard, which are fulfilled by the MTS-800, 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.

Features
Automatic Testing Capabilities
Full compliance with several immunity test as ISO 11452-8, MIL-STD-461 RS101, CS101, CS109, IEC/EN 55103-2, IEC/EN 61000-4-8, SAE J1113-2, SAE J1113-22, Ford ES-XW7T-1A278-AC, GM W3097, PSA B21 7110, Renault 36-00-808, DC-11224, DC 10614 and similar standards. Furthermore the MTS-800 allows emission measurements according to MILSTD- 461E/F RE101, CE101 and IEC/EN 55103-1.
Software
Any function is controlled via a software 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 software is written in LabVIEW which guarantees stable and fast performance on any Microsoft® Windows platform.
Components
MTS-800 consists of 3 independent modules: a signal generator (DC – 250 kHz), a power amplifier (800 W output maximum, DC –1MHz bandwidth) and spectrum analyzer (16 Bit, 1 MSPS sampling rate). All modules can be used as stand-alone units.
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 at a self-calibration process automatically in about a minute.
Accessories
Frankonia provides also many different coils and loop sensor which are ideally suited for the described tests. Any additional equipment is ready to use without a need for recalibration. Not only our own equipment can be used with the MTS-800, but also user defined coils. A calibration mode is included in the software to complement the magnetic test system with any further equipment.
Further features and possibilities
Helmholtz Coils
Several Helmholtz coils are available for susceptibility tests. We also offer tri-axial Helmholtz coils which are suitable for MTS-800. To achieve 1000 A/m at 1 kHz, it is absolute necessary to use our Helmholtz coils and an optional compensation board.

Coupling Transformer
MIL-STD-461 CS 101 requires a coupling transformer for conducted susceptibility tests. Frankonia has developed a coupling transformer which meets all requirements. Due to direct coupling to voltage mains, the coupling transormer has an additional differential amplifier for common mode rejection of the AC mains. Using the coupling transformer without this amplifier can destroy any measurement instrument due to overvoltage.
Testing equipment acc. to IEC/EN 55103-2
IEN/EN 55103-2 requires certain immunity tests for frequencies from 50 Hz to 10 KHz. The following test equipment fulfills all requirements according to IEC/EN 55103-2, annex B.
