Set or return the point on a pulse, which is used to define the beginning of the pulse?s active interval.

Declaration: Btn55xxx.h
Implementation: Btn55xxx.dll

#define BTN55XXX_ATTR_START_GATE 1150035
ViStatus Btn55xxx_GetAttributeViReal64(
ViSession Vi,
ViConstString RepCapIdentifier,
ViAttr AttributeID,
ViReal64* AttributeValue
);

ViConstString RepCapIdentifier,
ViAttr AttributeID,
ViReal64 AttributeValue
);

Parameters
Vi
The ViSession handle that you obtain from the IviDriver_init or IviDriver_InitWithOptions function. The handle identifies a particular instrument session.
RepCapIdentifier
A physical or virtual repeated capability identifier. For valid values, see the Channel repeated capability.
AttributeID
Must be BTN55XXX_ATTR_START_GATE.
AttributeValue (GetAttribute)
Returns the current value of the attribute. The user must specify the address of a variable that has the same data type as the attribute.
AttributeValue (SetAttribute)
The value to which to set the attribute.
Remarks
This point is defined in percent of the total pulse duration, with 0% corresponding to the midpoint of the rising edge, and 100% corresponding to the midpoint of the falling edge, as defined by the mesial setting. For most pulse "on" average power measurements, it is desirable to exclude the rising and falling intervals, and only measure power over the active portion of the pulse. This is often known as time gating, and is used for the automatic pulse measurements returned by FETCh:ARRay:AMEASure:POWer.
