This window shows the result of a Radiated Emission Burst measurement, as it is described in the ETSI EN 300 328 standard. Also see the Radiated Emission Burst TSF window on how tho configure the burst test.
During the measurement, the resulting measurement values such as Max. e.i.r.p, medium utilisation, Duty cycle, Min. Gap time,Max. Sequence time and RMS are calculated and shown.
The following values are available:
 Graph
|
Shows the measurement result of the burst measurement. The individual measurement of each selected powermeter will be shown, and also the combined measurement result of all the graphs. It is possible to zoom-in on the measurement data to have more measurement details. |
| Measurement Values
|
Shows some final resulting measurement values as it is required by the ETSI EN 300 328 |
| Max. e.i.r.p.
|
Shows the maximum effective isotropic radiated power of the last combined measurement data. |
| Medium Utilisation
|
Shows the percentage of the medium utilisation of the last combined measurement data. |
| Duty Cycle
|
Shows the percentage of the time that a transmission was active during the last combined measurement data. This is the total TxSequence time compared to the total TxGap time. |
| Min. Gap Time
|
Shows the smallest period of time that was designated as a gap during the last combined measurement data. |
| Max. Sequence Time
|
Shows the largest period of time that was designated as a transmission during the last combined measurement data. |
| RMS
|
Shows the total RMS power of the complete last combined measurement data (including the gap and transmissions). This value should be the same as the power meter reading of True RMS powermeter. |
| Measurement Settings
|
Contains more measurement parameters that can be changed. |
| Carrier Frequency
|
The primary frequency that will be measured by the powermeters. This frequency is used to correct the measurement result of the powermeters. |
| Manual
|
Selects the manual triggering mode, where a new measurement is only performed when the Trigger button is pressed. |
| Trigger
|
Starts a new measurement of all the selected powermeters with the configured measurement settings. Also the combined measurement data will be recalculated and also the Measurement Values will be recalculated. |
| Auto
|
Selects the auto triggering mode. A new measurement will be started using the interval that is specified at the Auto setting. Also the combined measurement data will be recalculated and also the Measurement Values will be recalculated. |
| 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 |
| Measure time
|
The total time for the measurement |
| Sample Rate
|
The sample rate that should be used by the powermeters |
| Gap Time
|
The Gap Time specifies the minimum time that the measurement samples should be below the Trigger level to designate that period of time as a gap in the transmission |
| Threshold Level
|
The Threshold Level defines a dB difference to the maximum measured burst value, which is used to determine if a measured burst value is designated as a transmission. Any burst that has a maximum value that is more than Threshold Level below the maximum burst value during the complete Measure time will not be designated as a transmission. |
| Assembly Gain
|
The gain of the antenna that is normally connected to an output of the EUT. This Assembly Gain is used to calculate the total e.i.r.p. power. |
| Beamforming Gain
|
The gain of the additional benefit of the combining of the multiple antenna's of the EUT. This Beamforming Factor is used to calculate the total e.i.r.p. power. |
| Powermeters
|
Shows the list of currently selected powermeters that will be used during the measurement |
| Add
|
Allows to add one or more power meters to your test. |
| Edit
|
Shows the device driver configuration of the selected powermeter |
| Remove
|
Removes the selected powermeter from the list of powermeters that will be used |
| Connected
|
Shows the connection state with the selected powermeters. Also the connection with the powermeters can be disabled or re-activated by pressing the Connected button. |
