TVOLt
TVOLt
query
When
the
:MEASURE:TVOLT
query
is
sent,
the
displayed
signal
is
searched for
the defined
voltage
level
and
transition.
The
time interval
between
the trigger
event
and
this
defined
occurrence
is
returned
as
the
response
to
this
query.
The
<
voltage
>
can
be
specified
as
a
negative
or
positive
voltage.
To
specify a
negative
voltage,
use
a
minus
(-)
sign.
The
sign
of
<
slope
>
selects
a rising
(+
)
or
falling
(-)
edge.
The
magnitude
of
<
occurrence
>
defines
the
occurrence
to
be
reported.
For
example,
+ 3
will
return
the
time
for
the
third
time
the
waveform
crosses
the
specified
voltage
level
in
the
positive
direction.
Once
this
voltage crossing
is
found,
the
oscilloscope
will
output
the
time at
that
crossing
in
seconds,
with the
trigger
point
(time
zero)
as
the
reference.
If
the
specified
crossing
cannot
be
found,
the
oscilloscope
outputs
+
9.99999E
+
37.
This will happen
if
the
waveform
does
not
cross
the
specified
voltage,
or
if
the
waveform
does
not
cross
the
specified
voltage
for
the
specified
number
of
times
in
the
specified
direction.
