The exact function of
Data -> Mem
depends on the number of memory traces associated with the active
data trace:
•
If no memory trace is associated with the active trace, a new memory trace is generated.
•
If several memory traces are associated with the active trace, the current measurement data
overwrites the last generated or changed memory trace.
Coupling of data and memory traces
When a memory trace is generated from a data trace, it is displayed in the same diagram area and
inherits all channel and trace settings from the data trace.
The following display settings of a data trace and the associated memory traces are
fully coupled
.
Changing a property of one trace affects the properties of all other traces.

All settings in the
Trace – Format
menu
•
All settings in the
Trace – Scale
menu
Selection of the measured quantity
(Trace – Meas)
is possible for the data trace but disabled for the
memory traces.
Channel settings made for a memory trace act on the associated data trace. Some of the channel settings
for a data trace (e.g. the
Stimulus
range) also affect the display of the memory traces.
If the sweep type of a data trace is changed so that the stimulus ranges of the data traces and the
memory traces become incompatible, all coupled memory traces are removed from the diagram area and
deleted.
Remote control:
CALCulate<Chn>:MATH:MEMorize
Math = Data/Mem
Activates the mathematical mode where the active data trace is divided by the last generated memory
trace. The division is calculated on a point-to-point basis: Each measurement point of the active trace is
divided by the corresponding measurement point of the memory trace. The result of the division is a
mathematical trace and replaces the active data trace in the diagram area. The mathematical trace is
updated as the measurement goes on and the analyzer provides new active trace data.
This function is disabled unless a memory trace is coupled to the active data trace. Trace coupling
ensures that the two traces have the same number of points and that the mathematical trace Data/Mem is
well-defined.
Remote control:
CALCulate<Chn>:MATH:FUNCtion DIVide
Math = Data-Mem
Activates the mathematical mode where the last generated memory trace is subtracted from the active
data trace. The subtraction is calculated on a point-to-point basis: Each measurement point of the memory
trace is subtracted from the corresponding measurement point of the active trace. The result of the
subtraction is a mathematical trace and replaces the active data trace in the diagram area. The
mathematical trace is updated as the measurement goes on and the analyzer provides new active trace
data.
This function is disabled unless a memory trace is coupled to the active data trace. Trace coupling
ensures that the two traces have the same number of points and that the mathematical trace Data-Mem is
