:MEASure:DEFine
(see page 1368 )
Command Syntax
:MEASure:DEFine <meas_spec>[,<source>]
<meas_spec> ::= {DELay | THResholds}, for remaining syntax, see:
•
":MEASure:DEFine DELay Command Syntax"
on page 467
•
":MEASure:DEFine THResholds Command Syntax"
on page 468
The :MEASure:DEFine command sets up the definition for measurements by
specifying the delta time or threshold values. Changing these values may affect
the results of other measure commands. The table below identifies which
measurement results that can be affected by redefining the DELay specification or
the THResholds values. For example, changing the THResholds definition from the
default 10%, 50%, and 90% values may change the returned measurement result.

NOTE
The DELay portion of the MEASure:DEFine command has been deprecated, and you should
instead use the :MEASure:DELay:DEFine command to specify delay measurement parameters.
The delay measurement now allows an edge occurrence of zero (0) to specify automatic edge
selection. The limitation of this command is that you cannot specify a negative slope with an
occurrence count of zero (0).
