Setting Up Measurements
The display will have at least one data sample 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 the high and low
levels of the gating signal occur independent of 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.
