ps6000SetTriggerChannelConditions

PICO_STATUS ps6000SetTriggerChannelConditions

(

short handle,

PS6000_TRIGGER_CONDITIONS * conditions,

short nConditions

)

This function sets up trigger conditions on the scope's inputs. The trigger is defined by

one or more PS6000_TRIGGER_CONDITIONS structures that are then ORed together.

Each structure is itself the AND of the states of one or more of the inputs. This AND-

OR logic allows you to create any possible Boolean function of the scope's inputs.

If complex triggering is not required, use ps6000SetSimpleTrigger.

Applicability

All modes

Arguments

handle, the handle of the required device.

conditions, an array of PS6000_TRIGGER_CONDITIONS

structures specifying the conditions that should be applied to each

channel. In the simplest case, the array consists of a single element.

When there is more than one element, the overall trigger condition is

the logical OR of all the elements.

nConditions, the number of elements in the conditions array.

If nConditions is zero then triggering is switched off.

Returns
