:MEASure Commands
<slope> ::= {+ | -}
<occurrence> ::= integer
This command defines the behavior of the :MEASure:DELay? query by specifying
the start and stop edge to be used. <edge_spec1> specifies the slope and edge
number on source1. <edge_spec2> specifies the slope and edge number on
source2. The measurement is taken as:
delay = t(<edge_spec2>) - t(<edge_spec1>)
The :MEASure:DELay command and the front-panel delay measurement use an auto-edge
NOTE
selection method to determine the actual edge used for the measurement. The
:MEASure:DEFine command has no effect on these delay measurements. The edges specified
by the :MEASure:DEFine command only define the edges used by the :MEASure:DELay? query.
:MEASure:DEFine
:MEASure:DEFine THResholds,<threshold spec>[,<source>]
THResholds
<threshold spec> ::= {STANdard}
Command Syntax
<threshold mode> ::= {PERCent | ABSolute}
for <threshold mode> = PERCent:
<upper>, <middle>, <lower> ::= A number specifying the upper, middle,
for <threshold mode> = ABSolute:
<upper>, <middle>, <lower> ::= A number specifying the upper, middle,
• STANdard threshold specification sets the lower, middle, and upper
• Threshold mode PERCent sets the measurement thresholds to any user-defined
• Threshold mode ABSolute sets the measurement thresholds to absolute values.
Query Syntax
:MEASure:DEFine? <meas_spec>[,<source>]
<meas_spec> ::= {DELay | THResholds}
The :MEASure:DEFine? query returns the current edge specification for the delay
measurements setup or the current specification for the thresholds setup.

ABSolute thresholds are dependent on channel scaling (:CHANnel<n>:RANGe

these values first before setting ABSolute thresholds.
