gage_set_trigger_view_offset
Syntax
C:
void GAGEAPI gage_set_trigger_view_offset (int32 offset);
Visual BASIC:
Sub gage_set_trigger_view_offset (ByVal offset As Long)
Remarks
The gage_set_trigger_view_offset routine allows the application program to change where data transfer
begins when using gage_trigger_view_transfer, gage_trigger_view_transfer_2 or
gage_trigger_view_transfer_3 by offsetting the trigger address. Once the offset has changed, it keeps its
new value until the program is restarted or it is changed again.
The default value for the offset is 0, which denotes the trigger address. A negative offset can be used to
capture pre-trigger data. A positive offset can be used to start transfer from after the trigger address.
Care should be taken when using a negative number so that you don’t get data from before the start
address. The valid start, trigger and ending addresses can be obtained from a call to
gage_calculate_addresses.
Return Value
None.
