Parameters

selectorString  String

Specifies the signal name and result name. Example: "signal::sig1", "result::r1" "signal::sig1/result::r1". You can use the BuildRangeString2(String, Int32) method to build the selector string.

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.

spurFrequency  Double

Upon return, contains the array of frequencies, in hertz (Hz), of all detected spurs across all ranges.

spurAmplitude  Double

Upon return, contains the array of powers, in dBm, of all detected spurs across all ranges.

spurMargin  Double

Upon return, contains the array of differences between the spur amplitude and the absolute limit at the spur frequency.

spurAbsoluteLimit  Double

Upon return, contains the array of thresholds, in dBm, used to calculate the margin of the detected spurs.

spurRangeIndex  Int32

Upon return, contains the array containing range indices corresponding to the detected spurs.
