Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int FetchCompressionPoints(string selectorString, double timeout, ref double[] inputCompressionPoint, ref double[] outputCompressionPoint)
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Pass an empty string. The signal name that is passed when creating the signal configuration is used. |
| timeout | double | Specifies the timeout, in seconds, for fetching the specified measurement. Set this value to an appropriate time longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete. |
| inputCompressionPoint | ref double[] | Returns the theoretical input power, in dBm, at which device gain drops by the compression level, specified through AMPM Compression Point Level (dB) property, from a gain reference computed based on the value that you specify for the AmpmCompressionPointGainReference attribute. |
| outputCompressionPoint | ref double[] | Returns the theoretical output power, in dBm, at which device gain drops by the compression level, specified through AMPM Compression Point Level (dB) property, from a gain reference computed based on the value that you specify for the AmpmCompressionPointGainReference attribute. |
Returns
Returns the status code of this method. The status code either indicates success or describes an error or warning condition.
