Configures the segment measurement offset and length for the segments.
Syntax
int32 __stdcall RFmxSpecAn_PAVTCfgSegmentMeasurementInterval(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 segmentMeasurementOffset, float64 segmentMeasurementLength)
Parameters
| Name | Direction | Type | Description |
|---|---|---|---|
| instrumentHandle | [in] | niRFmxInstrHandle | This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function. |
| selectorString | [in] | char | This parameter specifies a Selector String comprising of the signal name and segment number. If you do not specify the signal name, the default signal instance is used. The default value is "segment0". |
| segmentMeasurementOffset | [in] | float64 | This parameter specifies the time offset from the start of the segment for which the phase and amplitude, amplitude, or frequency error values are computed. This value is expressed in seconds. This attribute is valid only when you set the RFMXSPECAN_ATTR_PAVT_MEASUREMENT_INTERVAL_MODE attribute to Variable. The default value is 0. |
| segmentMeasurementLength | [in] | float64 | This parameter specifies the duration within each segment over which the phase and amplitude, amplitude, or frequency error values are computed. This value is expressed in seconds. This attribute is valid when you set the RFMXSPECAN_ATTR_PAVT_MEASUREMENT_INTERVAL_MODE attribute to Variable. The default value is 1 millisecond. |
Returns
Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred.
To obtain a text description of the status code and additional information about the error condition, call the RFmxSpecAn_GetError function.
The general meaning of the status code is as follows:
Value | Meaning |
|---|---|
0 | Success |
Positive Values | Warnings |
Negative Values | Errors |
