How to perform a MIL-STD-461 CS109, Conducted susceptibility, structure current test
This application note explains how the MIL-STD-461 CS109, Conducted susceptibility, structure current test can be performed with RadiMation®
The exact requirements and test methods for the CS109 are specified in the MIL-STD-461.
Necessary equipment
The following devices are necessary to perform the CS109 test:
- Signal generator
- Amplifier
- Coupling Transformer
- Current sensor
- Cable drivers with corrections
- Sensor power meter / Analyser
- 0.5 Ohm resistor
- Isolation Transformer
Tips
|
Define the test level
Create a correction file for the test level
First create a correction file in RadiMation® and specify the test level (See 'FIGURE CS109-1. CS109 limit.').
Ensure that the correction file has a Frequency column and a Current column with the unit set to dBuA.
Store the test level as correction file on disk.
This correction file with the test level will be used during EUT testing.
EUT Testing
EUT Testing equipment
The configuration of the eut test site should contain the following devices:
# | Device name | Tab in testsite configuration window | note |
---|---|---|---|
Signal Generator | Devices 1 | The signal generator to use | |
Amplifier | Devices 1 | The amplifier to use | |
Sensor powermeter | Devices 2 | The power meter or analyser to use for measuring the current | |
Current Sensor | Devices 2 | The current sensor to use with transfer factor attached to the driver | |
Injection device | Devices 2 | The injection device to use | |
Cables | |||
① | Cable current -> power meter | Cables | Cable (1) with a correction file specified for the cable loss |
Configure the EUT test
To perform the test on the EUT, create a conducted immunity multiband test. The conducted immunity multiband test, can be started by selecting from the menu:
Start | The start frequency of the test. For example 30 Hz. |
End | The stop frequency of the test. For example 100 kHz. |
Frequency Step | The frequency step, see Table III. |
Dwell Time | The dwell time. |
Frequency Change Mode | Constant. |
Modulation | CS109 does not specify a modulation to use. |
Test equipment | The equipment needed for the conducted immunity test. |
Location Type | Injection clamp. |
Test Level | Specify the current substitution method. Also add a "Measured Current Limit" |
Inputs | No inputs are needed. |
At TestLevel click Add to add a new Test level and select TestLevel - Current closed loop method
Description | The description of the test level. |
Test level | Variable current, and specify the correction file for the applicable test level. |
Tolerance | Specify the tolerance to use. |
When all settings are configured press Start Test to run the test.
EUT Test Result
Once the test is finished, the results of this test are stored in the EUT file and available as one of the performed Tests in the EUT file. Selecting the corresponding test result and pressing on Info will show the test results again.
Conclusion
The RadiMation® Conducted Immunity multiband test can be used to perform the CS109 test with a current closed loop method test level and a variable test level specified in a correction file.
