I'm using the N9320B spectrum analyser and the ivi driver found on the ni website to measure the channel power of a desired frequency
To do that i'm doing the following actions
1) agn9320ni_ConfigureMeasurementType (parameters are : MeasurementType 2)
2) agn9320ni_ConfigureAverage ( parameters are : AverageEnabled 1 ; AverageCount 5 ; AverageMode 1)
3) agn9320ni_ConfigureFrequencyCenterSpan (parameters are : CenterFrequency xxHz ; Span 2.0MHz)
4) agn9320ni_ConfigureCHP (parameters are : IntegrationBandwith 200KHz ; ChannelPowerSpan : 400KHz )
5) agn9320ni_ConfigureSweepCoupling (parameters are : resolutionBWauto 0 ; resolutionBW 3000Hz ; VideoBWauto 0 ; VideoBW 3000Hz ; SweepTimeAuto 1 ; SweepTime 0.1002s )
6) agn9320ni_ConfigureLevel (parameters are : amplitudeUnits ; inputImpedance 0 ; referenceLevel 0 ; ReferenceLevelOffset 0 ; AttenuationAuto 1 ; Attenuation 0 )
7) agn9320ni_ReadMeasurementCHP (parameters are : MaxTime_ms ; MainchannelPower = output ; powerdensity = output )
Now I have some issues with step 2 not being applied and step 4 not changing the channelpower to 400KHz
