Automated Reverberation Chamber Measurements
Reverberation chamber operation
A reverberation chamber has been used for electromagnetic compatibility (EMC) testing for over 20 years. This highly conductive cavity, excited by RF energy, generates a uniform electromagnetic field. Thanks to the mechanical stirrer, the field is statistically isotropic and randomly polarized, guaranteeing reliable measurements under the conditions defined by standards.
Automating Reverberation Tests: Compliance and Customization with BAT-EMC
BAT-EMC lets you automate reverberation tests for immunity and emission, in compliance with a wide range of standards such as DO 160, MIL STD, ISO 11451-5, ISO 11452-11, and 61000-4-21.With this software, you can configure all the parameters required by these standards.Although reverberation tests are relatively straightforward, they involve complex statistical calculations that BAT-EMC manages for you, ensuring compliance or enabling customized testing.
Test and calibration
BAT-EMC makes it easier to perform immunity tests in accordance with ISO 11452-11, EN 61000-4-21, MIL-STD, and DO-160 F and G standards. The software allows you to configure the mode stirrer for continuous or step-by-step rotation by defining the number of positions and the required rotation time.
Types of calibration
3 types of calibration can be performed:
empty calibration
Validates that the field is uniform and isotropic at the lowest usable frequency (LUF). Perform once
Loaded calibration
Confirm that the field remains uniform and isotropic with a load simulating the maximum load of the equipment under test (EST), also run once.
Calibration with Equipment (EST)
Estimates the actual TSE load
These calibrations are optional, depending on standard requirements.
Mesures lors de la calibration à Vide
Lors de la calibration à vide, deux types de mesures sont effectuées :
E field
Evaluation of the volume of the uniform field zone and the LUF frequency.
Power received on antenna
Field strength/power ratio measurement in the empty chamber.
A third measurement can include direct power and, if necessary, reflected power.
Key BAT-EMC features
BAT-EMC allows you to define the following elements:
-
- Chamber volume
- Efficiency factors for transmitting and receiving antennas
- Homogeneity limit
BAT-EMC exports all measurements and statistics, enabling you to make your own calculations for research and development.If a standard changes, Nexio integrates the new formula, while giving you the option of creating your own formulas.
Pour déterminer le nombre minimal de positions du brasseur, effectuez un étalonnage à vide avec un grand nombre de positions. BAT-EMC analysera toutes les mesures pour calculer le nombre optimal qui répond aux exigences d’uniformité.
Nexio propose une offre intégrale pour couvrir les tests en chambre réverbérante, tant pour l’émission que pour l’immunité.
Automatic execution: The software automatically executes immunity tests.
Manual mode: The operator can adjust parameters such as :
- Frequency
- Modulation
- Angle
- Generator level
Control tools are also available for monitoring test equipment (MAE).
As with all BAT-EMC tests, you can export results to Excel and generate highly customizable reports in Word.
Advantages of the BAT-EMC reverberation chamber
EUT in the uniform field area
Immunity tested in all directions, including on cables, for more realistic and reliable results.
Absorbent-free
Reduce installation costs while generating a higher electric field for even more effective testing, thanks to the absence of absorbers.
Excellent field/power efficiency
Benefit from the use of less expensive amplifiers or obtain a higher field strength than in an anechoic chamber.
