Boundary for ‘Less than” trigger in Trigger mode API_SCOPE_MODE_GREATER_OR_LESS_THAN on
APE cards. The voltage range that this value is representing is dependent on the coupling that was set with
the function ApiCmdScopeSetup().
Coupling
Value
Description
Extern 30V
0..1023
Representing the voltage range of -15V..+15V (steps of 29.3mV)
Extern 3V
0..1023
Representing the voltage range of -1.5V..+1.5V (steps of 2.9mV)
Stub 30V
0..1023
Representing the voltage range of -15V..+15V (steps of 29.3mV)
Stub 3V
0..1023
Representing the voltage range of -1.5V..+1.5V (steps of 2.9mV)
Note: Tis parameter is only available on APE MILScope modules. On APX,
ACX MILScope modules this value must be set to zero.
