Part 6: IEEE 488.2 Command Reference
CURSOR_VALUE?, CRVA?
Description
The CURSOR_VALUE? query returns the values measured by the specified cursors for a given trace.
There are important differences in the function of this query between MAUI instruments and legacy
LeCroy instruments:
l The keyword ALL should not be used; neither should multiple keywords. If they are used, the word
UNDEF is returned.
l The specified trace must be visible (turned on), and the cursor mode currently set on that trace
must be the same as in the query. If it is not the same, UNDEF is returned.
Tip: Use the PARAMETER_VALUE? query to obtain measurement parameter values.
Query Syntax
<trace>:CURSOR_VALUE? [<mode>]
<trace>:= C1 to Cn, F1 to Fn, M1 to Mn, TA to TD
<mode>:= {HABS, HREL, VABS, VREL}
Note: TA through TD are for backward compatibility. Although accepted, they are not returned by
queries.
Cursor modes are:
l HABS - Horizontal Absolute cursor
l HREL - Horizontal Relative cursors
l VABS - Vertical Absolute cursor
l VREL - Vertical Relative cursors
Response Format
<trace>:CURSOR_VALUE HABS,<abs_hor>
<trace>:CURSOR_VALUE HREL,<delta_hor>,<abs hor_ref>,<abs hor_dif>,<slope>
<trace>:CURSOR_VALUE VABS,<abs_vert>
<trace>:CURSOR_VALUE VREL,<delta_vert>,<abs vert_ref>,<abs vert_dif>
Note: The dV/dt value <slope> is displayed in the appropriate trace descriptor box.
