#4193: Issue auto perform CS114

Post by afrank »

From Release Notes RadiMation version 5.8.37 :
#4193: Issue auto perform CS114.
Where can I find more info about how to run CS114 : Calibration and testing?

Regarding the issue #4193: Issue auto perform CS114
The original question/remark was:
still present the issue about CS114, which is not possible to perform automatically. The issue is about the fact that there are two conditions to check, one for current and one for power, clearly expressed in the standard, 461 version F, almost at the end of paragraph 5.13.2
Practically: if the forward power is below the value of the calibration, the current should be 6dB or greater than the limit. So is the current which commands the test, and not the power. Is the exact reversed condition of automotive bulk current injection, where the power rules the test (you apply the same value of forward power, if the current is not reached, than increase the power up to a factor 4).
We then investigated the MIL-STD 461F, and responded with:
The MIL-STD 461F (in section 5.13.2) indeed states that:
The EUT shall not be influenced when the pre-calibrated current is injected.
The EUT is also passing if during testing the really injected current is 6 dB (or even more) higher than the calibrated limitation (and the EUT is still not influenced).
In practice this means that the pre-calibrated current should be applied during the EUT testing, and that the EUT testing can also continue to the next test frequency if the really flowing current is 6 dB above the pre-calibrated level.

This test can be configured in a Conducted Immunity Multiband test.
The Conducted Immunity Multiband test should be configured to include the following test-levels:
* Current substitution method (specifying the pre-calibrated calibration file, and the required test-level)
* Measured Current Limit (specifying a limitation that is 6 dB higher that the required test-level)

Also see: viewtopic.php?f=5&t=81 for a more detailed description of the available test-levels.
I hope that this gives you information, to configure RadiMation correctly to be able to perform the CS114 test. If you still have questions, please respond on this topic.

Best regards,
John
