• Threshold mode ABSolute sets the measurement thresholds to absolute values.
ABSolute thresholds are dependent on channel scaling (:CHANnel<n>:RANGe
or :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.
Return Format
for <meas_spec> = DELay:
{ <edge_spec1> | <edge_spec2> | <edge_spec1>,<edge_spec2>} <NL>
for <meas_spec> = THResholds and <threshold mode> = PERCent:
THR,PERC,<upper>,<middle>,<lower><NL>
<upper>, <middle>, <lower> ::= A number specifying the upper, middle,
and lower threshold percentage values
between Vbase and Vtop in NR3 format.
for <meas_spec> = THResholds and <threshold mode> = ABSolute:
THR,ABS,<upper>,<middle>,<lower><NL>
<upper>, <middle>, <lower> ::= A number specifying the upper, middle,
and lower threshold voltages in NR3
format.
for <threshold spec> = STANdard:
THR,PERC,+90.0,+50.0,+10.0
