The Trigger Tab
Becomes true when the specified pattern occurs in the specified number
of samples consecutively.
• Find pattern2 n times after pattern1, before pattern3 occurs
Becomes true when the second specified pattern occurs in a specified
number of samples after the the first specified pattern but without the
third specified pattern occurring anywhere in between.
• Store n samples
Becomes true when the specified number of samples are stored.
• Wait n external clock states
Becomes true when the specified number of external clocks have
occurred.
• Wait for arm in
When the logic analyzer is armed by another instrument (as specified in
the Intermodule window), this trigger function becomes true when the
arm signal is received.
• Wait for second analyzer to trigger
When the logic analyzer's pods are assigned to two analyzers, this trigger
function becomes true when the other analyzer triggers.
• Wait for flag
Becomes true when the specified flag has the specified value. This trigger
function tests for a flag event.
• Set/clear/pulse flag
Becomes true on any sample and sets, clears, pulse sets, or pulse clears
the specified flag. This trigger function inserts a flag action.
• OR Trigger
When the logic analyzer is armed by another instrument (as specified in
the Intermodule window), this trigger function becomes true when a
pattern occurs a specified number of times OR when the arm signal is
received.
