Slew Rate Trigger (R&S
RTH-K19)
The slew rate trigger is also known as transition trigger. It triggers if the transition time
from the lower to higher voltage level (or vice versa) is shorter or longer as defined, or
outside or inside a specified time range.
The slew rate trigger finds slew rates faster than expected or permissible to avoid over-
shooting and other interfering effects. It also detects slow edges violating the timing in
pulse series.

Description of settings
Upper Trigger Level / Lower Trigger Level
Set the upper and lower voltage thresholds for the slew rate trigger. The time measure-
ment starts when the signal crosses the first trigger level, and stops when the signal
crosses the second level. The first trigger level is the upper or lower level depending
on the selected slope.
