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
trigger mode.
