Trigger
User’s manual chapter 6, “Triggers”
There are three main categories of triggers: Edge/State triggers, Width triggers and Enhanced triggers.
Edge/State Triggers
Edge Trigger
Trigger occurs on the edge
(rising or falling) of a trigger
source. You can select a
trigger source* of
measurement input signal,
external trigger signal, or
commercial power supplied
from the instrument.
Edge(Qualified) Trigger
Trigger occurs on the
edge of a single trigger
source while each input
signal’s specified
conditions are true.
Edge(OR) Trigger
Trigger occurs if the edge
conditions of any one of
the multiple trigger sources
is true.
Width Triggers
Pulse Width Trigger
Pulse(Qualified) Trigger
Trigger occurs if the Pulse
Width trigger conditions are
true while the status of
each input signal meets the
specified conditions.
Pulse State Trigger
Trigger occurs when a relationship between the time in
which the logical (state) condition of the specified input
signal becomes true or not true, and a specified time,
becomes true. You can also have state conditions be
judged on the edge of the specified input signal and
triggers activated on the timing of the edge.
Trigger occurs depending on
whether the conditions
became true or not for a
shorter or longer duration than
a reference time specified in
advance.
*
A trigger source is a signal to which trigger activation conditions are applied.
** Supports software version 1.60 or later.
*** Supports software version 2.00 or later.
**** Supports software version 2.40 or later.
***** Supports software version 4.20 or later.
State Trigger
Trigger occurs when the
logical (state) condition of
the specified input signal is
true, or stops being true.
You can also have state
conditions be judged on
the edge of the specified
input signal and triggers
activated on the timing of
the edge.
Enhanced Triggers
TV Trigger
Trigger occurs on a video
signal.
Serial Trigger**
Trigger occurs on the
data pattern of a serial
bus signal.
Trigger occurs on the
data pattern of a LIN bus
signal.
Trigger occurs on the data
pattern of a UART bus
signal.
I
2
C Trigger**
Trigger occurs on the start
condition of an I2C bus
signal, address/data/
pattern, Non-ACK, general
call address, or start
byte/high speed mode.
SPI Trigger**
Trigger occurs on a data
or data pattern of an SPI
bus signal.
Trigger occurs on a pattern
of the SOF, error frame,
data frame/remote frame
of a CAN bus signal.
