abstract void SetLowerMask( 
   IEnumerable<double>^ frequencies,
   IEnumerable<double>^ amplitudes
) 

Parameters

frequencies

Frequencies in Hz. If FrequencyReferenceStyle is set to FrequencyMaskTriggerFrequencyReference.Center then values are Hz relative to Center. If FrequencyReferenceStyle is set to FrequencyMaskTriggerFrequencyReference.Absolute then values are absolute Hz. This parameter must be the same length as the amplitudes parameter. A value of null may be used to clear the mask.

amplitudes

Amplitudes. If AmplitudeReferenceStyle is set to FrequencyMaskTriggerAmplitudeReference.Range then values are in dB relative to the Range of the trigger channel. If AmplitudeReferenceStyle is set to FrequencyMaskTriggerAmplitudeReference.Absolute then values are in dBm. This parameter must be the same length as the frequencies parameter. A value of null may be used to clear the mask.

Target Platforms: Windows 11 Professional or Enterprise; Windows 10 Professional, Enterprise, or Education (64-bit)
