ESTArt
ESTArt
command/query
The
:MEASURE:ESTART
command
causes
the instrument to position
the start marker on the specified edge and slope
of
the displayed
waveform.
All
edges must be
displayed
and are counted from the left
edge
of
the
display. The
start
marker
is
positioned where
VMarker
1
intersects the waveform.
The
desired
edge
is
specified by
sending an
integer value after the command name.
If
a
positive integer
is sent,
the
oscilloscope will place
the start
marker
on
a
positive-going waveform
edge.
If
a
negative integer
is
sent, the start
marker will
be
placed
on
a
negative-going waveform edge.
If
VMarker
1
does not intersect the
waveform
as
specified,
the
error
message
"Edges required not found"
is
displayed.
The
ESTART
query returns the currently specified
edge.
Note
The
short
form of
this
command
does
not follow
the
defined
convention. The short form "EST"
is
the
same for
ESTART
and
ESTOP,
so be
careful not to send
this
form for
the
ESTART
command. Sending "EST' will
produce an
error.
Command
Syntax:
:MEASure:ESTArt
<edge>
Where:
<edge
>
::
=
-127
to
127 excluding
0
(if
a
positive
value
is
sent the
+
sign
may
be
omitted
or
a
space
may be
used)
Example:
OUTPUT
707;":MEASURE:ESTART
2"
This example places the
start
marker
at
the second displayed
positive-going intersection
of
the waveform and
VMarker
1.
