will output nothing at this tap.
To set triggered output streams, you should use the
TRIGGERED
command detailed below.
5.6 Triggering
TRIGGERS
Syntax:
components TRIGGERS
Selects which component or components can generate an
STA/LTA trigger. Only these components will be examined by
the triggering algorithm.
components
is an integer below 16, whose binary bits represent
the
Z
(1),
N
(2),
E
(4) and auxiliary (8) components respectively
as described above. Issuing
0 TRIGGERS
will disable the
triggering system.
TRIGGERED
Syntax:
tap components TRIGGERED
Selects which component or components will be
output
when a
trigger is generated, and at which tap (sample rate).
tap
is the tap number at which to output the triggered stream.
You can set which taps output which sample rate using the
SAMPLES/SEC
command, described above.
components
is an integer below 16, which represents which
components to output in the same fashion as in the
CONTINUOUS
command, above.
(This command and the previous one have similar names;
remember that a component
TRIGGERS
the system, whilst taps
and components are
TRIGGERED
.)
STA
Syntax:
Z-secs N-secs E-secs X-secs STA
Sets the length of the “short-term” averaging period in the
STA/LTA
triggering algorithm.
