Lower level
Sets the lower 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:LOWer on page 471
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 - and 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 definition
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.
SCPI command:
TRIGger<m>:SLEW:RANGe on page 471
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 minimum
slew rate limits, respectively.
SCPI command:
TRIGger<m>:SLEW:RATE on page 472
±Delta
Defines a time range around the given slew rate.
SCPI command:
TRIGger<m>:SLEW:DELTa on page 472
3.3.1.10 Data2Clock
With the Data2Clock event - also known as setup/hold - you can analyze the relative
timing between two signals: a data signal and the synchronous clock signal. Many sys-
tems 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 inband signals.
The event 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.
