The display will have at least one data sampl e marked as valid (high level) per
trace point. Or else you can use the Max Hold function to complete a trace
over several sweeps. Multiple sweeps fill the gaps because th e h ig h and lo w
levels of the gating signal occur independent o f the grating position.
Gated triggering has no time limit for the high or low level. It can be used to
characterize pulses as narrow as a few microseconds, or to obtain a spectrum
whose timing exceeds the maximum 6.5 ms delay of the ADC trigger mode.
