Get the current trigger hysteresis
word GetTriggerHys( byte byCh, double *dHysteresis )
Description:
This routine is used to retrieve the current Trigger Hysteresis.
The hysteresis is the minimum voltage change that is required to
comply with the trigger conditions. This is used to minimize the
influence of the noise on a signal on the trigger system.
Input:
byCh
The channel whose Trigger Hysteresis is to be
retrieved (1, 2, 3, 4).
Output:
dHysteresis
The current Trigger Hysteresis.
Return value
E_NO_ERROR
E_INVALID_CHANNEL
E_NO_HARDWARE
Set the trigger hysteresis
word SetTriggerHys( byte byCh, double dHysteresis )
Description:
This routine changes the hysteresis, see also
GetTriggerHys
.
Input:
byCh
The channel whose Trigger Hysteresis is to be
set (1, 2, 3, 4).
dHysteresis
The new trigger hysteresis.
Output:
Return value
E_NO_ERRORS
E_INVALID_VALUE
E_INVALID_CHANNEL
E_NO_HARDWARE
Upper and lower limits of the hysteresis:
Slope
Lower limit
Upper limit
rising
0
level + sens
falling
0
sens - level
Note
The Trigger Hysteresis applies only to analog trigger sources, not to
digital trigger sources.
When window trigger is selected, the Trigger Hysteresis controls the lower level
of the trigger window.
