Parameter Description Notes
Pre-trigger recording
Specifies, in seconds, how many
pre-event records to capture.
The actual number of records
set in the high-speed Sag/Swell
data recorder’s Pre-trigger
Records setup register = (2 x
system frequency) x (number of
seconds).
If system frequency is changed,
the recording duration for Pre-
trigger recording and Post-
trigger recording automatically
adjusts to reflect the new
frequency setting.
Post-trigger
recording
Specifies, in seconds, how many
post-event records to capture.
The actual number of records
set in the high-speed Sag/Swell
data recorder’s Post-trigger
Records = (2 x system
frequency) x (number of
seconds).
If system frequency is changed,
the recording duration for Pre-
trigger recording and Post-
trigger recording automatically
adjusts to reflect the new
frequency setting.
Total # of recordings
Specifies how many burst data
log sets to save in long-term
memory (NVRAM). The actual
number of records is configured
in the high-speed Sag/Swell
data recorder’s Depth setup
register = (Total # of recordings)
x (Pre-trigger Records + Post-
trigger Records + 1). For details
on how a data log set is
calculated, see "Data recorder
burst data" on page 213.
When burst data logging is
enabled, the equivalent number
of records for 2 burst data log
sets is allocated in short-term
memory (RAM). The actual
number of records set in the
high-speed Sag/Swell data
recorder’s Buffer Depth setup
register = 2 x (Pre-trigger
Records + Post-trigger Records
+ 1).
