Interv. width
Defines the time between two pulses.
SCPI command:
TRIGger<m>:INTerval:WIDTh on page 469
±Delta
Defines a range around the "Interval width" value.

3.3.1.9 Slew Rate
The slew rate trigger, also known as transition trigger, can detect fast or slow edges
selectively. It triggers on edges, if the transition time from the lower to higher voltage level
(or vice versa) is shorter or longer as defined, or outside a specified time range.
The trigger event finds slew rates faster than expected or permissible to avoid over-
shooting and other interfering effects. It also detects very slow edges violating the timing
in pulse series.
Slope
Sets the edge type for the trigger event.
"Positive"
Selects the rising edge, that is a positive voltage change.
"Negative"
Selects the falling edge, that is a negative voltage change.
"Both"
Selects the rising as well as the falling edge. This option is not available
if the trigger source is the external trigger input.
SCPI command:
TRIGger<m>:EDGE:SLOPe on page 457
TRIGger<m>:ANEDge:SLOPe on page 459
TRIGger<m>:SLEW:SLOPe on page 470
Upper level
Sets the upper voltage threshold. When the signal crosses this level, the slew rate mea-
surement starts or stops depending on the selected slope.
SCPI command:
TRIGger<m>:LEVel<n>:SLEW:UPPer on page 471
