Trace to Window
Copy a stored data trace (real part only) to the User window. Use the knob to pick a trace
which already contains data and press [Enter]. To see the effects of the new window the
User window must be selected.
The trace data is interpolated if necessary in order to provide the window function with
the correct number of points. The trace length is mapped to the entire window length.
The User window may be used with time records of any length.
Command: TRWI d, i
Window to Trace
Copy the current window of the active display to the real part of a stored data trace. Use
the knob to pick a trace and press [Enter].
<Window to Trace> always stores a trace with 2048 points. This corresponds to the
longest possible time record (800 line baseband). Using this trace in User Math requires
attention to the lengths of other operands in any user function.
Command: WITR d, i
Window Form
Select the Window Form of the User window [Non-Symmetric, Symmetric]. This softkey
only affects the User window.
Use Symmetric if the User window is centered or symmetric in the time record. Phase
will be measured relative to the center of the time record. Uniform, Hanning, Flattop,
BMH and Kaiser windows are all symmetric.
Use Non-Symmetric if the User window is non-symmetric. Phase will be measured
relative to the start of the time record. Force and Exponential windows are non-
symmetric.
Command: WSYM (?) d {, i}
