Performing an ETSI EN300328 MIMO measurement[edit]

This application note explains how a MIMO measurement can be performed with RadiMation® Free as it is described in the ETSI EN300328.

It is assumed that device drivers for the used powermeters are already configured in the configuration of RadiMation®. Otherwise see Device driver configuration in Chapter 2 of the RadiMation® Manual.

Create a new EUT-file by selecting from the menu bar:

   Menu.svg File
      Menu.svg New
         Menu.svg EUT

Specify a filename for the new EUT-file and select OK. A new EUT-window will now be opened.

To start the Burst measurement select from the menu bar:

   Menu.svg Tests
      Menu.svg Radiated Emission
         Menu.svg Burst

SelectRadiatedEmissionBurstFromMenu.png

Press New to create a new TSF-file.

The Radiated Emission Burst TSF window will now be opened in which the burst test can be configured.

In this TSF window it is important to Add a powermeter, and to configure the measurement parameters.


ScreenElementDescription.svg Powermeters Shows the list of currently selected powermeters that will be used during the measurement
ScreenElementDescription.svg Add Allows to add one or more power meters to your test.
ScreenElementDescription.svg Edit Shows the device driver configuration of the selected powermeter
ScreenElementDescription.svg Remove Removes the selected powermeter from the list of powermeters that will be used
ScreenElementDescription.svg Carrier Frequency The primary frequency that will be measured by the powermeters. This frequency is used to correct the measurement result of the powermeters.
ScreenElementDescription.svg Trigger level Specifies the power level for the trigger level of the powermeters. The powermeters will assume that a measurement sample is part of a burst if the measurement sample is above the specified Trigger level
ScreenElementDescription.svg Measurement time The total time for the measurement
ScreenElementDescription.svg Sample Rate The sample rate that should be used by the powermeters
ScreenElementDescription.svg Gap Time The Gap Time specifies the minimum time that no burst is present in the measurement data, to assume that a gap is present in the transmission
ScreenElementDescription.svg Threshold Level
ScreenElementDescription.svg Assembly Gain
ScreenElementDescription.svg Beamforming Factor


The Gap Time, Threshold Level, Assembly Gain and Beamforming Factor are terms that are explained in the ETSI EN300328 standard.

Press Start Test to start the measurement test with multiple power meters. Enter a filename to save the TSF-file, so it can be used again in the future.

The measurement is then started and the results are shown in the Radiated Emission Burst Status window.

During the measurement, all parameter such as Max e.i.r.p, medium utilisation, Duty cycle, Min Gap time and Max. Sequence time and RMS are calculated and shown. When the measurement is finished configuration parameters can be changed if desired, and a new measurement can be triggered by pressing the Trigger button.

The measurement results can be saved into the created EUT file by pressing the Close button.
