Trace/Det
Trace/Det
Accesses the trace keys to store and manipulate trace information.
Each trace consists of a series of points in which amplitude data is
stored. The analyzer updates the information for any active trace
with each sweep.
Trace

Retains the maximum level for each trace point of the selected
trace. Updates the trace point value if a new maximum level is
detected in successive sweeps.
Key access:

Min Hold
Retains the minimum level for each trace point of the selected
trace. Updates each minimum trace point if a new minimum level is
detected in following sweeps.
Key access:
Trace/Det > Min Hold
