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.)
Notation
HREL
the cursor value under track cursor
mode
VREL
the dalta volt-value, curA volt_value
and curb volt_value under manual
cursor mode
Note:
For non-SPO models , VREL is the dalta volt-value
under manual cursor mode.
QUERY SYNTAX
<trace>: CuRsor_Value? [<mode>,…<mode>]
<trace> : = { C1, C2, C3, C4}
<mode> : = { HREL, VREL }
RESPONSE FORMAT
<trace> : CuRsor_Value HREL,
<delta_hori>,<delta_vert>,<A->T>,
<A->V>,<(delta_vert)/(delta_hori)>
<trace> : CuRsor_Value VREL,<delta_vert>
EXAMPLE
The following query reads the dalta volt value
under manual cursor mode (VREL) on Channel 2:
Command message:
C2:CRVA? VREL
Response message:
C2:CuRsor_Value VREL 1.00V
