SV106A User Manual
The Trigger position enables the user to
select the trigger type: Level - , Level + ,
Slope - , Slope + , Gradient - or
Gr .
In each interval of the measurement, defined by Trig. Step , the triggering condition is checked and:
•
if Level + is selected, the triggering condition is fulfilled only when Source has the greater value than
determined by Level , otherwise the triggering condition is not fulfilled.
•
if Level
–
is selected, the triggering condition is fulfilled only when Source has the lower value than this
determined by Level , otherwise the triggering condition is not fulfilled.
•
if Slope + is selected, the triggering condition is fulfilled only when the rising value of Source is passing
the level determined by Level .
•
if Slope
–
is selected, the triggering condition is fulfilled only when the falling value of Source is passing
the level determined by Level .
•
if Gr is selected, the triggering condition is fulfilled only when the signal has the greater level
than determined by Level and the gradient of the signal is greater than determined by Gradient .
Otherwise the triggering condition is not fulfilled.
•
if Gradient - is selected, the triggering condition is fulfilled only when the signal has the lower level than
this determined by Level and the gradient of the signal is lower than determined by Gradient . Otherwise
the triggering condition is not fulfilled.
Step for checking the triggering
condition
The Trig. Step position enables the user
to select interval (integration period) for
condition
evaluation: equal to
Logger step ( path: <Menu> /
Measurement / Data Logging /
Logger Setup ), 100ms , 1.0s , and equal to
Meas. Period ( path: <Menu> /
Measurements / General Settings ). If
Meas. Time is selected the triggering
condition is checked every second and
RMS is averaged from the beginning of
the
measurement ( Meas. Time is
displayed in the right upper corner of the
display right under the Real Time Clock).

Source for triggering condition and
channel of triggering signal
The Source position enables the user to
select the type of source for triggering
condition calculation:
Vector , Profile 1 or
Spectrum (available for 1/1 Octave and
1/3 Octave functions).
The Channel position enables the user to
select the channel of triggering source.
Depending on value of the
Source
parameter, the value of Channel will be
different.
