# CAPLfunctionTestWaitScopePerformSignalTransitionTime

# testWaitScopePerformSignalTransitionTime

[Valid for](../../../Shared/FeatureAvailability.md): CANoe DE • CANoe4SW DE

## Function Syntax

* `long testWaitScopePerformSignalTransitionTime (message aMessage, ScopeAnalyseRange range, dword flags, long thresholdStart, long thresholdEnd, ScopeBitTransitionTimeResult result, ScopeAnalyseHandle handle); // form 1`
* `long testWaitScopePerformSignalTransitionTime (char nodeName[], ScopeAnalyseRange range, dword flags, long thresholdStart, long thresholdEnd, ScopeBitTransitionTimeResult result, ScopeAnalyseHandle handle); // form 2`
* `long testWaitScopePerformSignalTransitionTime (linFrame aMessage, ScopeAnalyseRange range, dword flags, long thresholdStart, long thresholdEnd, ScopeBitTransitionTimeResult result, ScopeAnalyseHandle handle); // form 3`
* `long testWaitScopePerformSignalTransitionTime (frFrame aMessage, ScopeAnalyseRange range, dword flags, long thresholdStart, long thresholdEnd, ScopeBitTransitionTimeResult result, ScopeAnalyseHandle handle); // form 4`

## Description

* **Form 1**: Measures the transition time of rising and falling edges of a CAN message within the defined area.
* **Form 2**: Measures the transition time of rising and falling edges of all Tx messages of an ECU node within the defined area.
* **Form 3**: Measures the transition time of rising and falling edges of a LIN message within the defined area.
* **Form 4**: Measures the transition time of rising and falling edges of a FlexRay message within the defined area.

## Parameters

* **aMessage**: The message to be analyzed.
* **nodeName**: The ECU node name of a database node.
* **range**: The start and end of the transition time measurement. See [Class: scopeAnalyseRange](../../Scope/Classes/CAPLfunctionScopeAnalyseRange.md).
* **flags**:
  * **Bits**:
    * 0: Define threshold level unit:
      * 0 = Threshold level in mV
      * 1 = Threshold level in %
    * 1-3: Select signal for transition time measurement (only valid for CAN):
      * Bit 1 = 1 Use CANhigh
      * Bit 2 = 1 Use CANLow
      * Bit 3 = 1 Use CANdiff
    * 4-5: Rising/falling edge selection:
      * Bit 4 = 1 Use rising edges
      * Bit 5 = 1 Use falling edges
    * 6:
      * 0 = Use last occurrence for transition time measurement, where the voltage level is above or below the threshold level.
      * 1 = Use first occurrence for transition time measurement, where the voltage level is above or below the threshold level.
    * All other bits are reserved and must be set to 0.
* **result**: The transition time measurement result.
  * **ScopeBitTransitionTimeResult Selectors**:
    * **minValue**: The minimal transition time (float)
    * **maxValue**: The maximal transition time (float)
    * **averageValue**: The average transition time overall measured edges (float)
    * **stdDeviation**: The standard deviation of the transition time measurement (float)
    * **scopeSamplingPeriod**: The configured sample period of the scope device (float)
    * **countAnalyzedEdges**: The count of analyzed edges (long)
    * **countAnalyzedFrames**: The count of analyzed frames (long)
* **handle**: A unique ID. The same handle must be used for all bit analysis function calls.
  * **ScopeAnalyseHandle Selectors**:
    * **handle**: A unique ID (long)

## Return Values

* **1**: success
* **0**: timeout
* **\< 0**: Error occurred. See `EScopeCAPLFitDataReturnCode` in `ScopeBitAnalyse.cin`
