How to perform a MIL-STD RE102 Radiated emission test[edit]

This application note explains how the MIL-STD RE102 Radiated Emission test can be performed with RadiMation®. The RE102 test is described in the MIL-STD-461.

Equipment used[edit]

For this test four antennas are used.

Antenna Frequency range
Rod antenna 10 kHz to 30 MHz
Biconical antenna 30 MHz to 200 MHz
Double ridge horn 200 MHz to 1 GHz
Double ridge horn 1 GHz to 18 GHz

The following devices should be configured:

  • Receiver
  • 4 Antennas
  • Cables

Optionally[edit]

  • Antenna polarizer / tower, above 30 MHz both vertical and horizontal polarizations should be measured.

Configuration of the test sites[edit]

Create a test site for each antenna / frequency range:

Device name Tab in testsite configuration window note
Antenna Devices 1 Antenna for the required frequency range
Antenna tower Devices 1 Optional antenna tower
Spectrum Analyser Devices 2 The receiver used for the test
Cable preamp -> analyser Cables Cable with a correction file specified for the loss

Perform the test[edit]

To perform the test start a Radiated Emission Multiband test:

ScreenElementDescription.svg Start The start frequency of the test. For example 10 kHz.
ScreenElementDescription.svg Stop The stop frequency of the test. For example 150 kHz.
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
ScreenElementDescription.svg Step size The step size set in the receiver
ScreenElementDescription.svg Measure time The measure time set in the receiver
ScreenElementDescription.svg Preamplifier The preamplifier setting set in the receiver
ScreenElementDescription.svg Traces The type of trace set in the receiver
ScreenElementDescription.svg Test Equipment The equipment used for the measurement
ScreenElementDescription.svg Location type Set this to Antenna height, distance, polararization and angle
ScreenElementDescription.svg Max Height The max height for the antenna tower
ScreenElementDescription.svg Min Height The min height for the antenna tower
ScreenElementDescription.svg Steps The number of height positions to measure
ScreenElementDescription.svg Move during measurement If the antenna tower can move during the measurement
ScreenElementDescription.svg Optimize Height Find the optimal emission around a certain height
ScreenElementDescription.svg Distance The used antenna distance
ScreenElementDescription.svg Antenna Polarization Which polarization is used, Vertical, Horizontal or both
ScreenElementDescription.svg Start Angle The min turn table angle`
ScreenElementDescription.svg End Angle The max turn table angle
ScreenElementDescription.svg Steps The number of angles to measure
ScreenElementDescription.svg Turn during measurement If the turn table can move during the measurement
ScreenElementDescription.svg Optimize Angle Find the optimal emission around a certain angle
ScreenElementDescription.svg EUT Angle Offset The offset of the EUT on the table
ScreenElementDescription.svg Limit Lines The applicable limit lines can be added
ScreenElementDescription.svg All peaks above x below the limit line No peaks should be measured in RE102
ScreenElementDescription.svg Peak detection No peaks should be measured for RE102
ScreenElementDescription.svg Final peak measurement No final peak measurement is needed for RE102


When all parameters are configured for the RE102 test, press Start Test to perform the measurement. Repeat the test for each point to test.
