VDELta
VDELta
query
The
:MEASURE: VDELTA query outputs the voltage difference between
VMarker
1
and VMarker
2.
No
measurement
is
made when the
VDELTA
query
is
received
by the oscilloscope. The delta voltage
value
that
is
output
is the current value. This is
the same value
as
the front
panel delta
V.
