Lower level
Sets the lower voltage threshold. When the signal crosses this level, the slew rate
measurement starts or stops depending on the selected slope.
Remote command:
TRIGger<m>:LEVel<n>:SLEW:LOWer on page 1269
Range
Selects how the time limit for the slew rate is defined. The time measurement starts
when the signal crosses the first trigger level - the upper or lower level depending on
the selected slope. The measurement stops when the signal crosses the second level.
"Within"
Triggers on slew rates inside a given time range. The range is defined
by "Slew rate" and "±Delta".
"Outside"
Triggers on slew rates outside a given time range. The range defini-
tion is the same as for "Within" range.
"Shorter"
Triggers on slew rates shorter than the given "Slew rate" limit.
"Longer"
Triggers on slew rates longer than the given "Slew rate" limit.
Remote command:
TRIGger<m>:SLEW:RANGe on page 1270
Slew rate
For the ranges "Within" and "Outside", the slew rate defines the center of a range
which is defined by the limits "±Delta".
For the ranges "Shorter" and "Longer", the slew rate defines the maximum and mini-
mum slew rate limits, respectively.
Remote command:
TRIGger<m>:SLEW:RATE on page 1270
±Delta
Defines a time range around the given slew rate.
Remote command:
TRIGger<m>:SLEW:DELTa on page 1271
6.3.10 Setup & Hold trigger
Access: "Menu">"Trigger" > "Setup" tab > "Type = Setup & Hold"
With the Setup & Hold trigger you can analyze the relative timing between two signals:
a data signal and the synchronous clock signal. Many systems require, that the data
signal must be steady for some time before and after the clock edge, for example, the
data transmission on parallel interfaces. With this trigger type, you can also test the
time correlation of sideband and in-band signals.
In firmware versions < 5.00, the Setup & Hold was called Data2Clock trigger.
The trigger occurs if the data signal crosses the data level during the setup and hold
time. The reference point for the time measurement is defined by clock level and clock
edge.
