The ETSI EN 300 328 standard describes how measurements should be performed on radio devices transmitting on the 2.4 GHz ISM band.
The exact title of this standard is: "Electromagnetic compatibility and Radio spectrum Matters (ERM); Wideband transmission systems; Data transmission equipment operating in the 2,4 GHz ISM band and using wide band modulation techniques; Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive"
Relevant products:
- All equipment transmitting on the 2.4 GHz ISM band.
The latest version of this standard is 2.2.2 from 2019-07
Test procedures[edit]
Several different measurements are described in the ETSI EN 300 328.
| Clause | Measurement | Explanation |
|---|---|---|
| 4.3.1.2 | RF output power | RadiMation Application Note 102 explains how the MIMO measurement can be performed with RadiMation. |
| 4.3.1.3 | Duty Cycle, Tx-sequence, Tx-gap | RadiMation Application Note 102 explains how the MIMO measurement can be performed with RadiMation. |
| 4.3.1.6 | Medium Utilization (MU) factor | RadiMation Application Note 102 explains how the MIMO measurement can be performed with RadiMation. |
| 4.3.1.9 | Transmitter unwanted emissions in the out-of-band domain | This is a 'standard' emission test, which can be performed by a Radiated Emission Multiband or a Conducted Emission Multiband test. The to be measured frequency ranges and the applicable limits are however depending on the transmit frequency and transmit power of the device itself, so should be adjusted accordingly. |
| 4.3.1.10 | Transmitter unwanted emissions in the spurious domain | This is a 'standard' emission test, which can be performed on the antenna terminal or from the cabinet itself. The allocated transmit band and the out-of-band domain (which is linked to the allocated transmit band) do not have to be measured. The applicable limit should thus be adjusted to this accordingly. |
| 4.3.1.11 | Receiver spurious emissions | This is a 'standard' emission test, which can be performed on the antenna terminal or of the cabinet itself. |
| 4.3.2.2 | RF output power | RadiMation Application Note 102 explains how the MIMO measurement can be performed with RadiMation. |
| 4.3.2.3 | Power Spectral Density | The Power Spectral Density measurement can be performed by performing a 'standard' emission test, and then use the results of that emission measurement to perform the actual calculation of the Power Spectral Density in a 1 MHz bandwidth. After the measurement is finished the measurement results can be exported using Graphs > Export. The data can then be pasted in for example Microsoft Excel, which can then be used to calculate the Power Spectral Density for 1 MHz as it is described in clause 5.4.3.2 |
| 4.3.2.4 | Duty Cycle, Tx-sequence, Tx-gap | RadiMation Application Note 102 explains how the MIMO measurement can be performed with RadiMation. |
| 4.3.2.5 | Medium Utilization (MU) factor | RadiMation Application Note 102 explains how the MIMO measurement can be performed with RadiMation. |
| 4.3.2.8 | Transmitter unwanted emissions in the out-of-band domain | This is a 'standard' emission test, which can be performed by a Radiated Emission Multiband or a Conducted Emission Multiband test. The to be measured frequency ranges and the applicable limits are however depending on the transmit frequency and transmit power of the device itself, so should be adjusted accordingly. |
| 4.3.2.9 | Transmitter unwanted emissions in the spurious domain | This is a 'standard' emission test, which can be performed on the antenna terminal or from the cabinet itself. The allocated transmit band and the out-of-band domain (which is linked to the allocated transmit band) do not have to be measured. The applicable limit should thus be adjusted to this accordingly. |
| 4.3.2.10 | Receiver spurious emissions | This is a 'standard' emission test, which can be performed on the antenna terminal or of the cabinet itself. |
Most measurements in the standard allow that the measurement is done on the antenna terminal of the device if it is directly available, or otherwise an emission measurement of the total cabinet itself is allowed.
If the antenna terminal should be measured, it is a 'Conducted' emission measurement, and it is best to use the 'Conducted Emission Multiband' test, where the 'Antenna Terminal' is selected as the test type. The result will be presented as power values (in dBm, dBpW, W, mW, etc...).
If the cabinet itself should be measured, it is a 'Radiated' emission measurement, and it is best to use use the 'Radiated Emission Multiband' test, where the 'Antenna spurious and Harmonic outputs' is selected as the test type. The result will be presented as power values (in dBm, dBpW, W, mW, etc...).
