22 :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>)
:MEASure:DEFine
THResholds
Command Syntax
:MEASure:DEFine THResholds,<threshold spec>[,<source>]
<threshold spec> ::= {STANdard}
| {<threshold mode>,<upper>,<middle>,<lower>}
<threshold mode> ::= {PERCent | ABSolute}
for <threshold mode> = PERCent:
<upper>, <middle>, <lower> ::= A number specifying the upper, middle,
and lower threshold percentage values
between Vbase and Vtop in NR3 format.
for <threshold mode> = ABSolute:
<upper>, <middle>, <lower> ::= A number specifying the upper, middle,
and lower threshold absolute values in
NR3 format.
• STANdard threshold specification sets the lower, middle, and upper
measurement thresholds to 10%, 50%, and 90% values between Vbase and
Vtop.
• Threshold mode PERCent sets the measurement thresholds to any user-defined
percentages between 5% and 95% of values between Vbase and Vtop.
• Threshold mode ABSolute sets the measurement thresholds to absolute values.
ABSolute thresholds are dependent on channel scaling (:CHANnel<n>:RANGe
or ":CHANnel<n>:SCALe" on page 283:CHANnel<n>:SCALe), probe attenuation
(:CHANnel<n>:PROBe), and probe units (:CHANnel<n>:UNITs). Always set
these values first before setting ABSolute thresholds.
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.
NOTE
The :MEASure:DELay command and the front-panel delay measurement use an auto-edge
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.
