Command/Query
The TRIG_PATTERN command defines a trigger pattern. The
command specifies the logic composition of the pattern sources
(Channel 1, Channel 2, and Channel 4) and the conditions under
which a trigger can occur. Note that this command can be used
even if the complex trigger mode has not been activated.
Notation
L Low
H High
X Don’t Care
PR pattern present
EN pattern entered
AB pattern absent
EX pattern exited
The TRIG_PATTERN? query returns the current trigger pattern.
TRig_PAttern <C l_state>,<C2_state>,<C4_state>,<trig_condi-
tion>
<Cl_state> := {L,H,X}
<C2_state> := {L,H,X}
<C4_state> := {L,H,X}
<trig_condition> := {PR, AB, EN, EX}
TRiLPAttern?
TRiLPAttern <C l_state>,<C2_state>,<C4 state>,<trig_condi-
tion>
The following command configures the logic state of the pattern as
HLX (CH1 = H, CH2 = L, CH4 = X) and defines the trigger con-
dition as pattern absent (AB).
