command/query
The
:MEASURE:DEFINE
command sets
up the definition
for
a
measurement.
The
DEFINE
query returns the current setup.
Command Syntax:
:MEASure:DEFine
< measurement_spec

Where:
< measurement_spec > ::=
{DELay
<polarity>, <edge_num>, <level>,
<
polarity

<edge_num>,
<

| NWIDth
{MIDDIe
|
UPPer
| LOWer}}
Where:
<polarity> ::= {POSitive |
NEGative}
<edge_num
> ::
=
an integer, -127 to 127 (excluding
0)
specifying
a
displayed edge
<
level
>
::= {MIDDIe |
UPPer
| LOWer}
Example:
OUTPUT 707;":MEAS:DEFINE DELAY,POS1TIVE,1,UPPER,NEGATIVE,2,MIDDLE"
This example will
set
the parameters
for
a
time measurement from the
first
positive edge
at
the upper threshold level to the second negative edge
at
the middle threshold.
If
one source
is specifed, both parameters apply
to
that signal.
If
two sources are specified the measurement
is
from the
first
positive edge on
source
1
to the
second negative edge on source 2.
