- 1 minute(s) read
Sets an array of the the ohmic losses between the noise source and the input port of the DUT, as a function of the frequency. This value is expressed in dB. This loss is accounted for by the NF measurement when you set the SetDutInputLossCompensationEnabled(string, RFmxSpecAnMXNFDutInputLossCompensationEnabled) method to True. You must exclude any loss which is inherent to the noise source and is common between the calibration and measurement steps, and configure the loss using the SetYFactorNoiseSourceLoss(string, double[]) method. Specify the frequencies at which the losses were measured using the SetDutInputLossFrequency(string, double[]) method.
Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int SetDutInputLoss(string selectorString, double[] value)
Remarks
This method sets the value of NFDutInputLoss attribute.The default value is an empty array.
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
