Edge
Sets the slope to be found:
●
"Rising" to search for rise time
●
"Falling" to search for fall time
●
"Both" to search for rise and fall time
Remote command:
SEARch:TRIGger:RISetime:SLOPe on page 492
Upper Level, Lower Level
Set the upper and lower voltage thresholds. When the signal crosses the first level, the
rise/fall time measurement starts. It stops when the signal crosses the second level. To
let the instrument set the levels, tap "Find Threshold".
Remote command:
SEARch:TRIGger:LEVel:RISetime:LOWer on page 492
SEARch:TRIGger:LEVel:RISetime:UPPer on page 493
Comparison
Sets how the measured rise or fall time is compared with the given limits.
"Greater than"
Finds rise/fall times longer than the given "Rise/Fall Time".
"Lower than"
Finds rise/fall times shorter than the given "Rise/Fall Time".
"Equal"
Finds rise/fall times equal to the reference "Rise/Fall Time" if "Varia-
tion" Δt = 0.
If "Variation" ≠ 0, the setting finds rise/fall times within the range time
± Δt.
"Not equal"
Finds rise/fall times unequal to the reference value if "Variation" Δt =
0.
If "Variation" ≠ 0, the setting finds rise/fall times outside the range
time ± Δt.
