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.
