CURSOR
CURSOR_VALUE?, CRVA?
Query
DESCRIPTION The CURSOR_VALUE? query returns the values measured by the
specified cursors for a given trace. (The PARAMETER_VALUE?
query is used to obtain measured waveform parameter values.)
There are important differences in the function of this command
between X-Stream instruments and earlier LeCroy instruments.
The keyword ALL should NOT be used, neither should multiple
keywords. If they are used, the word UNDEF will be returned.
For the CRVA? query to work, the specified trace MUST be visible,
and the current cursor mode must be the same as in the query. If it
is not the same, UNDEF will be returned.
