R&S ZNB/ZNBT
The table contains an automatically assigned current number for each range plus the
following editable columns:
●
"Range On/Off" enables or disables the ripple limit check in each range. Disabling
the ripple limit check does not delete the range but hides the entry in the info field.
●
"Start Stimulus" is the smallest stimulus (x-axis) value of the range.
●
"Stop Stimulus" is the largest stimulus (x-axis) value of the range.
●
"Ripple Limit" is the maximum allowed difference between the largest and the
smallest trace value in the range.
The ripple limit range is displayed as two parallel, horizontal lines in the diagram. "Stop
Stimulus" - "Start Stimulus" is the length of both lines (if the range is within the sweep
range); "Ripple Limit" is their vertical distance. See
test definition",
Remote command:

Add / Insert / Delete / Delete All / Align All
The first four buttons below the range list extend, shorten, or reorder the list.
●
"Add" adds a new range to the list. The new range is inserted after the previously
selected range. The current range numbers are adapted; the start and stop stimu-
lus values are set so that an overlap is avoided. Moreover, the ripple limit is estima-
ted according to the measured ripple of the trace in the created range. The ana-
lyzer places no restriction on the number of ranges assigned to each trace.
●
"Insert" adds a new range before the active range (marked by a blue background in
the first column of the range list). The new range extends from the "Stop Stimulus"
value of the range before the active range to the "Start Stimulus" value of the active
range. Its ripple limit is estimated according to the measured ripple of the trace in
the created range. The range numbers in the list are adapted.
If no range is active, "Insert" is equivalent to "Add".
●
"Delete" removes the selected range from the list.
●
"Delete All" clears the entire range list so it is possible to define or load a new rip-
ple limit line.
●
"Align All" redefines existing sweep ranges such that they cover the overall sweep
range and have (almost) equal width. The ripple limits are estimated according to
the measured ripple of the trace in the created ranges.

Recall Ripple Test.../Save Ripple Test...
The buttons open an Open/Save File dialog to load a ripple limit line from a ripple limit
file or store the current ripple limit configuration to a file.
Ripple limit files are ASCII files with the default extension *.ripple and a special file
format. See
