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:
-
Tests
- Radiated Emission
- Multiband
-
-
-
 Start
|
The start frequency of the test. For example 10 kHz. |
| Stop
|
The stop frequency of the test. For example 150 kHz. |
| Reference Level
|
The reference level set in an analyser, not used in a receiver |
| Attenuation
|
The attenuation set in the receiver |
| RBW
|
The RBW set in the receiver |
| Step size
|
The step size set in the receiver |
| Measure time
|
The measure time set in the receiver |
| Preamplifier
|
The preamplifier setting set in the receiver |
| Traces
|
The type of trace set in the receiver |
| Test Equipment
|
The equipment used for the measurement |
| Location type
|
Set this to Antenna height, distance, polararization and angle |
| Max Height
|
The max height for the antenna tower |
| Min Height
|
The min height for the antenna tower |
| Steps
|
The number of height positions to measure |
| Move during measurement
|
If the antenna tower can move during the measurement |
| Optimize Height
|
Find the optimal emission around a certain height |
| Distance
|
The used antenna distance |
| Antenna Polarization
|
Which polarization is used, Vertical, Horizontal or both |
| Start Angle
|
The min turn table angle` |
| End Angle
|
The max turn table angle |
| Steps
|
The number of angles to measure |
| Turn during measurement
|
If the turn table can move during the measurement |
| Optimize Angle
|
Find the optimal emission around a certain angle |
| EUT Angle Offset
|
The offset of the EUT on the table |
| Limit Lines
|
The applicable limit lines can be added |
| All peaks above x below the limit line
|
No peaks should be measured in RE102 |
| Peak detection
|
No peaks should be measured for RE102 |
| 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.
