Estop - HP 54501A Programming Reference Manual

ESTOp
ESTOp
command/query
The
:MEASURE:ESTOP
command
causes
the instrument to position the
stop 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
stop marker
is
positioned where
VMarker
2
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 places
the stop
marker
on a
positive-going waveform edge. If
a
negative integer
is sent,
the stop
marker
is
placed on
a
negative-going waveform edge.
If
VMarker
2
does not intersect the
waveform
as
specified,
the
error
message
"Edges
required
not found"
is
displayed.
The ESTOP 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
ESTOP
command.
Sending "EST' will produce an
error.
Command Syntax:
:MEASure:ESTOp
<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;°:MEAS:ESTOP
-2"
This example
places
the
stop
marker
at the second displayed
negative-going intersection of the waveform
at
VMarker
2.
