The source turns on as soon as the output is turned on and remains on until the
source is turned off. As shown in the two timing diagrams, the static source
remains on for every measurement cycle. The Source-Delay portion of the SDM
cycle is omitted. With Trigger Delay set to zero, Trigger Latency is the time from
when the trigger event occurs to when the SourceMeter begins an A/D conver-
sion.
