•
Smoothing On activates the smoothing function for the active trace.
•
Smoothing Aperture... defines how many measurement points are averaged to smooth the
trace.
•
Import/Export Data stores the active trace to a file or loads a memory trace from a file.
•
Shift Response Value ... opens a dialog to define a user-correction to the measured values.
•
Shift Stimulus Value... shifts a memory trace in horizontal direction.
Many of the functions of the Trace Funct menu act on the active trace. Data traces and the associated
memory traces share many of their properties; see coupling of memory traces.
Data -> Mem
Stores the current state of the active trace as a memory trace. The memory trace is displayed in the
active diagram area with another color, and its properties are indicated in the trace list:
Memory traces are named Mem<n>[<Data_Trace>] where <n> counts all data and memory traces in
the active setup in chronological order, and <Data_Trace> is the name of the associated data trace.
Trace names can be changed in the Trace Manager dialog.
The exact function of Data -> Mem depends on the number of memory traces associated to 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.
To store the current measurement data to a new memory trace (without overwriting an existing
memory trace), or select and overwrite a particular memory trace, use -> Mem .
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 – Measure) 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.
