Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession | The ViSession handle that you obtain from the IviSpecAn_init or IviSpecAn_InitWithOptions function. The handle identifies a particular instrument session. Default Value: None |
| markerFrequencyCounter | ViBoolean | Specifies whether the frequency counter is enabled. The driver uses this value to set the IVISPECAN_ATTR_MARKER_FREQUENCY_COUNTER_ENABLED attribute. Valid Values: VI_TRUE; VI_FALSE Default Value: VI_FALSE |
| frequencyCounterResolution | ViReal64 | Specifies the frequency counter resolution. The measurement gate time is the reciprocal of the specified resolution. The driver uses this value to set the IVISPECAN_ATTR_MARKER_FREQUENCY_COUNTER_RESOLUTION attribute. Units: Hertz Default Value: 1.0 KHz Note: This value is ignored when the IVISPECAN_ATTR_MARKER_FREQUENCY_COUNTER_ENABLED is False. |
