ps4000SetTriggerChannelConditions

PICO_STATUS ps4000SetTriggerChannelConditions

(

short handle,

TRIGGER_CONDITIONS * conditions,

short nConditions

)

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

defining one or more 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.

Applicability

All modes

Arguments

handle, the handle of the required device.

conditions, a pointer to an array of 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 are several elements, 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

PICO_INVALID_HANDLE
