Fetches the AM-to-AM trace where the inputPowers array forms the x-axis of the trace, and the measuredAMToAM and curveFitAMToAM arrays form the y-axis of the trace.
Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int FetchAMToAMTrace(string selectorString, double timeout, ref float[] referencePowers, ref float[] measuredAMToAM, ref float[] curveFitAMToAM)
Remarks
This method maps to the RFmxSpecAn_AMPMFetchAMToAMTrace() function in C.
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies the result name. Example: "", "result::r1". You can use the BuildResultString(string) method to build the selectorString. |
| 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. |
| referencePowers | ref float[] | returns the array of reference powers, in dBm. |
| measuredAMToAM | ref float[] | Upon return, contains the gain values, in dB, corresponding to the input powers. |
| curveFitAMToAM | ref float[] | Upon return, contains the polynomial fit gain values, in dB, corresponding to the input powers. |
Returns
Returns the status code of this method. The status code either indicates success or describes an error or warning condition.
