9.1.39 ApiCmdScopeTriggerDefEx
Prototype:
AiInt16 ApiCmdScopeTriggerDefEx( AiUInt32 ulModuleHandle,
TY_API_SCOPE_TRG_EX * px_ScopeTrg );
Purpose:
This function is used to define a trigger condition for the APX, ACX, APE MIL-
Scope.
Note: This function is only usable with AIM’s APX, ACX, APE MIL-Scope module.

Trigger mode on which condition the trigger is activated
Value
Constant
Description
0
API_SCOPE_MODE_GREATER_THAN
Higher than the value given in parameter
ul_TrgValue (rising edge)
1
API_SCOPE_MODE_LESS_THAN
Lower than the value given in parameter
ul_TrgValue (falling edge)
2
API_SCOPE_MODE_GREATER_OR_LESS_THAN
Higher than the positive value given in
parameter ul_TrgValue or
lower than the negative value given in
parameter ul_TrgValue. On APE cards,
ul_TrgValue2 must be used to specify
lower boundary value.
3
API_SCOPE_MODE_COMMAND_SYNC
Reserved for future use only.
4
API_SCOPE_MODE_GREATER_THAN_SAMPLES
Higher than the value given in parameter
ul_TrgValue for a given number of
samples (parameter ul_TrgNbSamples)
(high pulse)
5
API_SCOPE_MODE_LESS_THAN_SAMPLES
Lower than the value given in parameter
ul_TrgValue for a given number of
samples (parameter ul_TrgNbSamples)
(low pulse)
7
API_SCOPE_MODE_BIU_BM
Reserved for future use only.
8
API_SCOPE_MODE_BIU_BC
Reserved for future use only.
9
API_SCOPE_MODE_BIU2_BM
Reserved for future use only.
10
API_SCOPE_MODE_BIU2_BC
Reserved for future use only.
11
API_SCOPE_MODE_DISCRETES
Reserved for future use only.
Note: The modes 3, 7, 8, 9, 10 and 11 are only defined for the APE MIL-Scope
module.
