Description
Specifies a time duration for which the signal must be quiet before the device arms the trigger. The signal is quiet when it is below the trigger level if the trigger slope, specified by NIRFSA_ATTR_IQ_POWER_EDGE_REF_TRIGGER_SLOPE, is set to NIRFSA_VAL_RISING_SLOPE or above the trigger level if the trigger slope is set to NIRFSA_VAL_FALLING_SLOPE.
By default this value is set to 0, which means the device does not wait for a quiet time before arming the trigger. This attribute is useful to trigger the acquisition on signals containing repeated bursts, but for which each burst may have large changes in signal power within itself. By configuring the minimum quiet time to the time between bursts, you can ensure that the trigger occurs at the beginning of a burst rather than in signal power change within a burst.
