CURSOR_VALUE?, CRVA?
Query
The CURSOR_VALUE? query returns the values measured by
the specified cursors for a given trace. (The PARAME-
~’ER_VALUE? query is used to obtain measured waveform
9arameter values.)
Notation
HABS Horizontal absolute
HREL
VABS Vertical absolute
VREL
Horizontal relative
Vertical relative
<trace>:CuRsor_VAlue? [<mode> ....
<mode>]
<trace> := {EA, EB, MC, MD, FE, FF, C1, C2, C35, C4~}
<mode>:= {HABS, VABS, HREL, VREL, ALL}
<trace>:CuRsor VAlue? <mode>[,<hor_value>],<vervalue>
[ ..... <mode> [, <hor_value>], <ver_value>]
For horizontal cursors, both horizontal as well as vertical values
are given, whereas for vertical cursors only vertical values are
given.
Note: If <mode> is not specified or equals ALL, all the measured
cursor values for the specified trace are returned. If the value of a
cursor could not be determined in the current environment, the
value UNDEF will be returned.
The following query reads the measured absolute horizontal value
of the cross-hair cursor (HABS) on Channel
