22.1.1 Interface description
The screen of the oscilloscope function looks like this, with two clearly different parts. The
left side and the lower side show the data of the variables to be shown, the trigger data, the
time base and the parameters that may be acted upon. The top right side shows the variables
graphically.
A Variables to represent in the graphic window. Up to 4 variables may be displayed at the
same time. The visibility and color associated with each variable may be defined in the
configuration page.
B Graphic window where the selected variables are represented. For each variable, it
shows the scale used to draw it.
C Time base.
D Trigger. In this area, the user may select the trigger conditions.
E Machine parameters to be set. With the oscilloscope, it is possible to change the value
of up to 20 machine parameters to check their effect during the adjusting process.
Some of this data may also be defined at the configuration screen. See
"22.1.3 Configuration screen" on page 405.
Trigger data,
In this area, the user may select the trigger conditions. The options offered by this trigger
data area are:
Trigger The trigger indicates when the data capture begins. If selected, the trigger
condition must be specified with the "Flank", "Level" and "Position" data.
If not selected, the data capture begins as soon as the user gives the
command to begin. The "Flank", "Level" and "Position" data are ignored.
Channel The channel indicates which variable or channel (CH1, CH2, CH3, CH4)
is to be used as reference or trigger condition.
Position (%) The (%) position is taken into account when Trigger has been selected and
it is defined as a percentage between 0% and 100%. It indicates the
number of samples to be taken before the Trigger. For example, a 10%
position indicates that 10% of the total number of programmed samples
will be taken before the Trigger and the remaining 90% after that instant.
The Trigger condition is evaluated after gathering the indicated % of
samples. If the position is defined as 50% and the Trigger condition takes
place after taking 10% of the samples, it is ignored until capturing 50% of
the samples.
Flank It may be up-flank (leading edge) or down-flank (trailing edge). It is taken
into account when trigger has been selected.
Trigger level It sets the value to be assumed by the variable to start capturing data. It
is taken into account when trigger has been selected.
