Agilent Technologies 5000 Series manual MEASureDELay? query, For threshold mode = PERCent

Commands by Subsystem 3

	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
N O T E
	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 THResholds Command Syntax

Query Syntax

:MEASure:DEFine THResholds,<threshold spec>

<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 158:CHANnel<n>:SCALe), probe attenuation (:CHANnel<n>:PROBe), and probe units (:CHANnel<n>:UNITs). Always set these values first before setting ABSolute thresholds.

:MEASure:DEFine? <meas_spec>

<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.
