Trace
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
1 2 3 4
Selects the trace for current use.
Key access:
Trace/Det > Trace 1 2 3 4
Clear Write
Erases any data previously stored in the selected trace, then
continuously displays any signals during each sweep of the
analyzer. This function is activated for trace 1 at power- on
and
Factory Preset
.
Key access:
Trace/Det > Clear Write
Max Hold
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:
Trace/Det > Max Hold
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

Holds and displays the amplitude data of the selected trace.
The trace register is not updated as the analyzer sweeps.
