All existing traces of the current setup are listed in a table with several editable (white) or non-editable
(gray) columns. Below the table the Trace Manager provides the following buttons:
• Add/Delete... opens a dialog to add a new trace or delete a trace.
• Coupling opens a dialog to define coupling criteria (channel, scale) for all traces in the table.
• Sort Table opens a dialog to change the order of the traces (rows) in the table.
Columns in the Trace Manager table
• Name indicates the current trace name. The default names for new traces are Trc<n> where
<n> is a current number. Current numbers in the trace names are necessary to make automatic
assignments, e.g. decouple the channel settings in the Coupling dialog.
• On indicates whether the trace is displayed on the screen (On) or invisible.
• Meas indicates the measured parameter.
• Type indicates whether the trace is a data trace (DAT), displaying the current measurement
data, or a memory trace (MEM).
• Channel indicates the channel of each trace.
• Area indicates the diagram area of each trace.
• Scale shows which traces use common scaling and format settings.
Rules for trace names
The analyzer can define mathematical relations between different traces and calculate new
mathematical traces (User Def Math). The trace names are used as operands in the mathematical
expressions and must be distinguished from the mathematical operators +, -, *, /, (, ) etc. This places
some restrictions on the syntax of trace names:
• The first character of a trace name can be either one of the upper case letters A to Z, one of the
lower case letters a to z, an underscore _ or a square bracket [ or ].
• For all other characters of a trace name, the numbers 0 to 9 can be used in addition.
The analyzer does not accept illegal trace names. If an illegal name is specified, the input field in the
Trace Manager turns red.

Add/Delete
Opens a dialog to add a new trace or delete a trace.
• Add creates a new trace and adds it to the list in the Trace Manager, assigning it to the channel
