How to perform a MIL-STD-461 CE102, Conducted Emissions, radio frequency potential, power leads test[edit]

This application note explains how the MIL-STD CE101, Conducted Emissions, radio frequency potential, power leads test can be performed with RadiMation®.

The exact requirements and test methods for the CE102 are specified in the MIL-STD-461.

Necessary equipment[edit]

The following devices are necessary to execute this test:

  • Receiver
  • LISN
  • Attenuator
  • Cable

Configuration of the test sites[edit]

The configuration of the equipment is a lisn connected with a cable to a receiver with a attenuator of 20 dB.

The configuration of the test site should contain the following devices:

Device name Tab in testsite configuration window note
LISN Devices 2 LISN
Spectrum Analyser Devices 2 The receiver used for the test
Cable preamp -> analyser Cables Cable with a correction file specified for the cable loss
Cable preamp -> analyser Cables Cable with the specified loss of the used attenuator

Perform the test[edit]

To perform the actual CE102 test, start a Conducted Emission Multiband test:

   Menu.svg Tests
      Menu.svg Conducted Emission
         Menu.svg Multiband

The complete test from 10 kHz up to 10 MHz has different settings for different frequency bands. All these different bands can be configured. The test can be configured with 2 bands, each using their applicable frequency range, measure time and bandwidth.

Band Frequency range RBW Step size Measure time receiver Measure time FFT receiver
Band 1 10 kHz - 150 kHz 10 kHz 5 kHz 0.015 s 1 s
Band 2 150 kHz - 10 MHz 10 kHz 5 kHz 0.015 s 0.15 s

In the following test configuration an EUT for "EUT power leads, AC and DC, for all applications" is tested.

ScreenElementDescription.svg Start The start frequency of the test. For example 10 kHz.
ScreenElementDescription.svg Stop The stop frequency of the test. For example 10 MHz.
ScreenElementDescription.svg Reference Level The reference level set in an analyser, not used in a receiver
ScreenElementDescription.svg Attenuation The attenuation set in the receiver
ScreenElementDescription.svg RBW The RBW set in the receiver, see table with different bands for possible values
ScreenElementDescription.svg Step size The step size set in the receiver, see table with different bands for possible values
ScreenElementDescription.svg Measure time The measure time set in the receiver, see table with different bands for possible values
ScreenElementDescription.svg Preamplifier The preamplifier setting set in the receiver
ScreenElementDescription.svg Traces The type of trace set in the receiver, for MIL-STD CE102 a peak detector is used
ScreenElementDescription.svg Test Equipment The equipment used for the measurement, see table with different bands for possible values
ScreenElementDescription.svg Location type Set this to "LISN"
ScreenElementDescription.svg LISN Select the LISN line(s) to test
ScreenElementDescription.svg Limit Lines The applicable limit line can be added, in this case "MIL-STD-461G CE102-1 (EUT power leads, AC and DC) for all applications"
ScreenElementDescription.svg All peaks above x dB below the limit line Which level above x dB below the limit line should detect peaks, no final peaks should be measured in MIL-STD CE102
ScreenElementDescription.svg Peak detection How many peaks should be detected automatically, no final peaks should be measured for MIL-STD CE102
ScreenElementDescription.svg Final peak measurement It is possible to perform a final measurement on a peak with a specific detector, no final peak measurement is needed for CE102


When all parameters are configured for the CE102 test, press Start Test to perform the conducted emission measurement.

Review the measurement[edit]

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. CE102 Test Result.png

Conclusion[edit]

The MIL-STD CE102 test is using different receiver settings depending on the frequency band. All these settings can be easily configured in a "Test Setup File" and tested with RadiMation®.
