:MEASure Commands
:MEASure:DEFine DELay,<delay spec>[,<source>]
<delay spec> ::= <edge_spec1>,<edge_spec2>
<edge_spec1> ::= [<slope>]<occurrence>
<edge_spec2> ::= [<slope>]<occurrence>
<slope> ::= {+ | -}
<occurrence> ::= integer
<source> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
This command defines the behavior of the :MEASure:DELay command/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.
<source> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 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.
