(

int16_t handle,

int16_t enable,

PS4000A_CHANNEL source,

int16_t threshold,

PS4000A_THRESHOLD_DIRECTION direction,

uint32_t delay,

int16_t autoTrigger_ms

)

This function simplifies arming the trigger. It supports only the LEVEL trigger types

and does not allow more than one channel to have a trigger applied to it. Any

previous pulse width qualifier is cancelled.

Applicability

All modes

Arguments

handle, the handle of the required device.

enabled, zero to disable the trigger, any non-zero value to set the

threshold, the ADC count at which the trigger will fire.

direction, the direction in which the signal must move to cause a

trigger. The following directions are supported: ABOVE, BELOW,

RISING, FALLING and RISING_OR_FALLING.

delay, the time, in sample periods, between the trigger occurring

and the first sample being taken.

autoTrigger_ms, the number of milliseconds the device will wait if

no trigger occurs.
