SVANTEK 977W User Manual
In the
Trigger Period
position, it is possible to select the time interval of checking
the triggering conditions. This parameter can be set on:
Log. Step
(same as
Logger Step
value),
0.5ms
,
100.0ms
and
1s
.
In the
Rec. Time
position, it is possible to select the time of signal recording after
triggering. If another triggering condition that satisfies the selected conditions
appears then the signal will be recorded for an additional
Rec. Time
. The
available values can be selected from
1s
to
8h
.
When
Pre Trigger
is higher than 0 then the wave signal start to be recorded
before the triggering condition moment. The period of such recording depends
on the sample frequency and bits per sample. The maximum pre trigger period
is:
for 24 bits per sample:
2s
for 48 kHz,
4s
for 24 kHz and
8s
for 12 kHz.
for 16 bits per sample:
4s
for 48 kHz,
8s
for 24 kHz and
16s
for 12 kHz.
5.4.6 Setting the markers
– Marker Setup
Marker is used to mark (or highlight) special events during the measurement such as "airplane flight" and is
nothing but an indication of the beginning and end of the block of logger results in which the event occurred. In
case of point markers there is no start and end of the marker, but only one record in the logger file. Markers are
activated in the result presentation window by pressing the arrow keys.
The
Marker Setup
enables the user to
assign a specific name for each marker,
select its type (normal or
Point
) and define
markers for event recording.
