Advanced Functions

RFmxBT_AbortMeasurements

int32 __stdcall RFmxBT_AbortMeasurements (niRFmxInstrHandle instrumentHandle, char selectorString[]);

Purpose

Stops acquisition and measurements associated with signal instance that you specify in the selectorString parameter, which were previously initiated by the RFmxBT_Initiate or measurement read functions. Calling this function is optional, unless you want to stop a measurement before it is complete. This function executes even if there is an incoming error.

Parameters

Input
Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxBT_Initialize function.
selectorString char[] Specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used.
Examples:
""
"signal::sig1"
You can use the RFmxBT_BuildSignalString function to build the selector string.

Return Value

Name Type Description
status int32 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 RFmxBT_GetError function.

The general meaning of the status code is as follows:
Value Meaning
0 Success
Positive Values Warnings
Negative Values Errors

RFmxBT_AnalyzeIQ1Waveform

int32 __stdcall RFmxBT_AnalyzeIQ1Waveform (niRFmxInstrHandle instrumentHandle, char selectorString[], char resultName[], float64 x0, float64 dx, NIComplexSingle IQ[], int32 arraySize, int32 reset, int64 reserved);

Purpose

Performs the enabled measurements on the I/Q complex waveform that you specify in the IQ parameter. Call this function after you configure the signal and measurement attributes. You can fetch measurement results using the Fetch functions or result attributes in the attribute node. Use this function only if the Recommended Acquisition Type attribute value is either IQ or IQorSpectral.

Parameters

Input
Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxBT_Initialize function.
selectorString char[] Specifies the signal name and result name. The result name can either be specified through this input or the resultName parameter. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name in this parameter, either the result name specified by the resultName parameter or the default result instance is used.
Example:
""
"signal::sig1"
"result::r1"
"signal::sig1/result::r1"
You can use the RFmxBT_BuildSignalString.
resultName char[] Specifies the name to be associated with measurement results. Provide a unique name, such as "r1" to enable fetching of multiple measurement results and traces. This input accepts the result name with or without the "result::" prefix.
Example:
""
"result::r1"
"r1"
x0 float64 Specifies the start time of the input y array. This value is expressed in seconds.
dx float64 Specifies the time interval between the samples in the input y array. This value is expressed in seconds. The reciprocal of dx indicates the I/Q rate of the input signal.
IQ NIComplexSingle[] Specifies an array of complex-valued time domain data. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.
arraySize int32 Specifies the size of the array. Set the arraySize parameter to 0 to get the size of all the arrays in the actualArraySize parameter.
reset int32 Resets measurement averaging. If you enable averaging, set this parameter to TRUE for the first record and FALSE for the subsequent records.
reserved int64 Reserved for future use. Any value passed to this parameter will be ignored.
