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.

When LOWLATENCY is active, this command is used to set the
components which are output as low-latency streams. Issuing 0
TRIGGERS will disable the low latency mode.

GTRIGGERS

Syntax: components GTRIGGERS

Selects which component or components can generate a level trigger.

Only these components will be examined by the triggering algorithm.

components is an integer below 16 with the same meaning as in
TRIGGERS.

S/WTRIGGER

Syntax: S/WTRIGGER

Issues a software trigger, causing the digitizer to trigger immediately,
and begin outputting triggered streams according to its configuration.

TRIGGERED

Syntax: tap components TRIGGERED

Selects which component or components will be output when a trigger
is generated, and at which tap (sample rate).
