Min Hold
Pressing causes the trace to be cleared and a new minimum-hold measurement
sequence to be started. A min hold sequence maintains the minimum level for each trace
point of the selected trace, and updates each trace point if a new minimum level is detected
in a successive sweep. Min Hold is restarted if any parameter is changed. Restarting Min
Hold also restarts averaging and max hold, because there is only one count for Average and
Hold.
