RadiMation Application Note 106

Powermeter parameter configuration

This application note describes how the measurement parameters of a Powermeter can be configured to get a fast and stable power measurement.

Each powermeter in RadiMation^® has a powermeter configuration tab in the device drivers. In this tab, the accuracy of power measurement can be optimized. This function allows to make multiple measurements, and wait until the value is stable. Using a measurement-loop.

Pre Wait Time

Wait time before starting the measurement-loop. Can be used to wait for a signal generator, and or amplifier to stabalize.

Measure

The minimum ammount of measurements in the measure loop. Continues to loop even if power level is stable.

Wait Time

The wait time before each measurement is taken, during the measurement-loop.

Max. Difference

If the measured power between each measurement in the measurement-loop, is less than this value. The measured power is stable. The loop will stop.

Max. Measure

The maximum ammount of measure times, for the measurement-loop

The powermeter can be used in the test to regulate signal generator values. The powermeter can also be used as monitoring input channel. For each powermeter usage, the multiple measurement loop can be configured.

Warning:

With the available settings, you can make measurements very slow. In some cases, you can end up in measuring noise during test. Then the maximum measure times will be used. You may need to decrease the Max. Measure value in that case.
