# CAPLfunctionTestWaitScopePerformSerialBitAnalysis

# testWaitScopePerformSerialBitAnalysis

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

## Function Syntax

```c theme={null}
long testWaitScopePerformSerialBitAnalysis (linframe aMessage, dword flags, dword msgFieldStart, dword msgFieldEnd, ScopeBitMaskPolygon bitMaskPolygon, long domVoltageThreshold , long recVoltageThreshold, ScopeAnalyseHandle handle);
```

## Description

Checks the bits of a LIN message against the defined bitmask.

## Parameters

* **aMessage**: The LIN message to be analyzed.

* **flags**: Reserved must be set to 0.

* **msgFieldStart, msgFieldEnd**: The start and end of the cutout to be fitted.

* **bitMaskPolygon**: The bitmask which shall be used.

  **ScopeBitMaskPolygon Selectors**

  * **maskPointCount**: Count of the points in the mask-arrays, Type: long
  * **data\_0\_Mask**: Voltage level in mV for dominant bits, Type: long\[]
  * **data\_1\_Mask**: Voltage level in mV for recessive bits, Type: long\[]
  * **timeOffset**: Relative position within bit in percent, Type: double\[]

* **domVoltageThreshold, recVoltageThreshold**: The voltage levels in millivolt used from the bit parser for detecting dominant and recessive bits.

* **handle**: A unique ID. The same handle must be used for all bit analysis function calls.

  **ScopeAnalyseHandle Selectors**

  * **handle**: A unique ID, Type: long

## Return Values

* **0**: No errors found
* **\< 0**: Error occurred.
