CURSOR - CURSOR_VALUE?, CRVA?
The CURSOR_VALUE? query returns the values measured by the specified cursors. The
PARAMETER_VALUE? query is used to obtain measured waveform parameter values.
The keyword ALL should not be used; neither should multiple keywords. If they are used, the word
UNDEF is 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 is returned.
Query Syntax
<trace>:CuRsor_VAlue? [<mode>]
<trace>:= {TA,TB,TC,TD,C1,C2,C3,C4}
<mode>:= {HABS, HREL, VABS, VREL}
Where:
HABS
- Horizontal absolute
HREL
- Horizontal relative
VABS
– Vertical absolute
VREL
– Vertical relative
Response Format
<trace>:CuRsor_VAlue HABS,<abs_hori>,<abs_vert>
<trace>:CuRsor_VAlue HREL,<delta_hori>,<delta_vert>,<abs vert_ref>,
<abs vert_dif>,<slope>
The dV/dt value <slope> is displayed in the appropriate trace label box.
<trace>:CuRsor_VAlue VABS,<abs_vert>
<trace>:CuRsor_VAlue VREL,<delta_vert>
For horizontal cursors, both horizontal and vertical values are given. For vertical cursors only vertical
values are given.
Example
The following query reads the measured absolute horizontal value of the cross-hair cursor (HABS) on
Channel 2:
C2:CRVA? HABS
Response message:
C2:CRVA HABS,34.2E-6 S, 244 E-3 V
