RFmxSpecAn_AMPMFetchDUTCharacteristics

This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function.

This parameter specifies a Selector String comprising of the signal name and result name. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. The default value is "" (empty string).

Example:

""

"signal::sig1"

"result::r1"

"signal::sig1/result::r1"

You can use the RFmxSpecAn_BuildSignalString function to build the selector string.

This parameter 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 function waits until the measurement is complete. The default value is 10.

This parameter returns the average linear gain, in dB, of the device under test, computed by rejecting signal samples suffering gain compression.

This parameter returns the theoretical output power, in dBm, at which gain of the device under test drops by 1 dB from its mean linear gain. This parameter returns NaN when the AM-to-AM characteristics of the device under test are flat.

This parameter returns the ratio, as a percentage, of l² norm of difference between the normalized reference and acquired waveforms, to the l² norm of the normalized reference waveform.
