Note  Many oscilloscopes have a small, non-zero value as the minimum value for this attribute. To configure the instrument to use the shortest trigger holdoff, you can specify a value of zero for this attribute. The specific driver coerces any value between zero and the minimum value to the minimum value. No other coercion is allowed on this attribute.

Description

Specifies the length of time the oscilloscope waits after it detects a trigger until the oscilloscope enables the trigger subsystem to detect another trigger. The units are seconds. The IVISCOPE_ATTR_TRIGGER_HOLDOFF attribute affects instrument operation only when the oscilloscope requires multiple acquisitions to build a complete waveform. The oscilloscope requires multiple waveform acquisitions when it uses equivalent-time sampling or when the IVISCOPE_ATTR_ACQUISITION_TYPE attribute is set to IVISCOPE_VAL_ENVELOPE or IVISCOPE_VAL_AVERAGE.
