EMC Control Unit
The ECU-6 is a central EMC test and control unit, which combines in just one compact box many major test components like signal generator, power meter, directional couplers and relay switching unit, which are needed for EMC tests. That reduces the cabling work and possible cabling mistakes to a minimum. Furthermore it includes general functions like EUT-monitoring and an interlock safety-system. With all the functions described above, the ECU-6 is a real all-rounder, which can be used for many different conducted and radiated immunity tests as well as control unit to switch between EMI-receiver and spectrum analyzer and different measuring antennas without time consuming cabling work. It allows to control and to switch automatically between up to four external amplifiers, all connected to the ECU-3/-6 and up to three different outputs for antennas or coupling devices (CDNs, EM-coupling clamp, BCI-clamps). The integrated signal generator is available to cover the frequency range from 9 kHz to 6 GHz. Amplitude modulation is available with a modulation rate of 1 Hz to 30 kHz and a modulation depth of 0 % to 90 %. Pulse modulation can be switched on with a repetition frequency of 0.1 Hz to 100 kHz and a duty cycle of 1 % – 99 %. In a word, it includes all requirements according to present EMC standards and it is best prepared for possible future changes.

Field Strength Meter
The Frankonia EFS field strength meters especially have been designed for field strength measurements / field homogeneity measurements during radiated immunity tests according to IEC/EN 61000-4-3 / -20. But it could also be used to measure the radiation exposure of the environment, for example at workplaces or flats.
The EFS is an isotropic miniature E-field sensor to ensure that the E-field will not be influenced by the size of the sensor itself. It even does not need any metering unit (which could also influence the field strength), because of its direct fibre optic output which allows direct connection of the sensor to the USB-interface of the control PC or laptop. The measuring values may be displayed via the individual IEC/EN 61000-4-3 / -20 control software or via a Windows software included in the delivery.
The EFS-10 / EFS-100 cover the frequency range from 10 kHz up to 9.25 GHz and are able to detect electrical field strength in the range from 0.14 V/m to 500 V/m (depending on type).
The sensors are battery operated by Li-Mn batteries, which allow a maximum operation time of 80 hours before recharging.

Relay-Switching-Unit
The RSU Relay Switching Unit is applicable for all fields of RF- and EMC measurements to switch (manualor remote-controlled) from one input to 2 or 3 outputs. Typical applications in measuring systemsare changeover switching between different amplifiers, antennas or power meters. This does also prevent circuit faults due to wrong cabling. By means of a selector switch on the front panel of the RSU it is possible to work in manual mode or remote- control mode via the RS232, USB or GPIB interface.
The input/output connectors of the relays are installed on the rear panel of the RSU, this allows an easy cabling when or where the RSU is mounted into a 19”-rack. A RSU can be equipped with a maximum of 4 relays with 2 or 3 outputs. The quantity of relays with 2 or respectively 3 outputs is variable. The delivery includes a Windows software for easy remote-controlled applications. However for extensive systems it is recommended to integrate the RSU driver into the system control software.
The easy to follow commands for RS232 and GPIB interfaces are listed in the user manual.

Double-stacked log.-periodic antennas have mainly been developed in order to reach the highest field strength levels acc. to automotive-, avionics- and military standards with as less as possible input power. Antenna gain saves amplifier power!
The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of 2.5dB compared to an ordinary LP antenna. This is especially important for immunity testing, where a maximum field strength and a good field uniformity is required. The beam- width in the E-plane and the H-plane are nearly identical, providing an optimized illumination of the EUT with minimized ground reflection influence.
Further the cross polar rejection of the AXL-80 is excellent and the high and flat gain of about 9dBi over a broad frequency range is the main advantage of the AXL-80. Because of its physical dimensions the main application of the AXL-80 is in bigger anechoic chambers / test sites for radiated immunity tests and emission measurements. From its technical / mechanical design it is a double- stacked log.-periodic antenna, consisting of two excellent ordinary log.-periodic structures. For easy transport and storage it is possible to remove the rear elements of the antenna, which are fixed by fast links.

The AXL-80ES special is nearly identical like the AXL-80E but with folded longest elements and smaller structure angle.
The stacked Log Periodic Dipole Antenna (Stacked LPDA) consists of two ordinary Log.-Per. structures. The excellent characteristics (flat gain over a large bandwidth, low SWR) of the ordinary LPDA designs could be maintained using the stacked LPDA design. The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of 2.5 dB compared to an ordinary LP antenna. This is especially important for immunity testing, where a maximum field-strength and a good field uniformity is required. The beam width in the E-Plane and the H-plane are nearly identical, providing an optimized illumination of the EUT with minimized ground reflection influence. Further the cross polar rejection of the AXL-80ES is excellent. The fast-links allows to disassemble the rear elements without any need for further tools within a few seconds. These fast-links divide the antenna into five parts, which can be stored and transported easily.

The AXL-200 has especially been designed for the generation of high field strength levels acc. to automotive immunity standards. The small dimensions of the antenna does also allow to keep the min. required distance of 25cm to the floor, when testing in vertical polarization.
From the mechanical design it´s a double-stacked logarithmic periodic antenna, consisting of two excellent ordinary log.-periodic structures. This design guarantees a high and flat gain of 9-10dBi over a large bandwidth and a low SWR.
The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of ca. 2 dB compared to an ordinary LP antenna. This is especially important for immunity testing, where a maximum field strength and a good field uniformity is required.

MIL-STD 461, RS 101:
Test device:
Magnetic-Field / Low-Frequency Test System
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.

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.
