SV106A User Manual
The
Enabled
position switches on/off the
Wave Trigger
.
In the
Rec. Limit
position the user may select time of signal recording after
triggering. If the triggering condition appears then the signal will be recorded
during the period defined in
Rec. Time
. The available values of
Rec. Limit
are:
Max Length
,
Fixed Len.
or
Off
.
When
Off
is chosen then the event signal will be recorded until the memory
is filled or while the trigger condition is fulfilled. When
Max Length
is chosen
then the signal will be recorded for the period defined by
Rec. Time
, but
can be stopped earlier, if trigger condition is not fulfilled any more. When
Fixed Len.
is chosen then the signal will be recorded for the period defined
by
Rec. Time
, even when the trigger condition ceases.
In the
Rec. Time
position the user may select the time of event signal
recording after triggering. If next triggering condition appears then the signal
will be recorded for an additional period defined by
Rec. Time
.

5.8 Measure trigger parameters selection
– Measure Trigger
The
Measure Trigger
position appears
only in the advanced instrument mode
(
path:
<Menu> /
Auxiliary Setup
/
Instrument Mode: Advanced Mode
).
The
Measure Trigger
sub-list enables
the user to set the parameters of measure
trigger.
<ENT>
The
Measure Trigger
is a context sub-list in which
Trigger
can be
switched off (
Off
) or on (all other than
Off
values). When
Trigger
is on it is
possible to determine the source of the triggering signal (
Source
), the
channel of source signal (
Channel
), its level (
Level
) and also the speed of
changes (
Gradient
). If
RTC
is selected as a trigger type, start time
(
RTC Start
) and repetition of triggering (
Repeat Every
) is defined.
Switching the triggering on and off
The triggering of the measurements (
Trigger
) can be switched off by means of the
<
>
push-buttons.
The triggering is switched on if one of its six available modes is selected:
Slope +
,
Slope
–
,
Level +
,
Level
–
,
Grad +
or
RTC
. If the instrument works with the switched-on trigger, the appropriate icon appears on the
display when the instrument is waiting for triggering (triggering condition is not fulfilled). The triggering condition
is checked every 5 milliseconds.
