RadiMation Application Note 162
How to perform a MIL-STD-461 RE103, radiated emissions, antenna spurious and harmonic outputs test.[edit]
This application note explains how the MIL-STD-461 RE103, radiated emissions, antenna spurious and harmonic outputs test can be performed with RadiMation®.
The "RE103, radiated emissions, antenna spurious and harmonic outputs" test applies as an alternative to CE106 for testing transmitters with their intended antennas, ensuring emissions do not exceed RE102 limits in transmit mode. It is preferred for systems with active antennas or non-standard impedance curves. It applies from 10 kHz to 40 GHz, excluding the signal bandwidth and ±5% of the fundamental frequency, with larger exclusions for high-power Navy shipboard systems.
The exact requirements and test methods for the RE103 are specified in the MIL-STD-461.
Necessary equipment[edit]
The following devices should be configured:
- Measurement receiver
- Band rejection network
- Attenuators / filters
- Antenna
EUT Testing[edit]
EUT Testing equipment
The configuration of the eut test site should contain the following devices:
| # | Device name | Tab in test site configuration window | note |
|---|---|---|---|
