Specified Conditions
The instrument must be in the quiescent state, with no interval scans in process, no
commands in the queue, no RS-232 or IEEE interface activity, and no front panel
activity if the latency and repeatability performance is to be achieved. For addition
information, refer to Chapter 5.

Maximum Latency
Latency is measured from the edge of the trigger input to the start of the first channel
measurement for the Specified Conditions (above).
