Basic Digital Operation
Using Waveform Markers
Placing a Marker on a Single Point
On the First Point
1. In the
Marker Utilities
menu ( page 134 ), press
Set Markers
.
2. Highlight the desired waveform segment.
In an ARB format, there is only one file (
AUTOGEN_WAVEFORM
) and it is already highlighted.
3. Highlight the desired marker number:
Press
Marker 1 2 3 4
.
4. Press
Set Marker On First Point
.
This sets a marker on the first point in the segment for the marker number selected in Step 3 .
On Any Point
Use the steps described in “Setting Marker Points in a Waveform Segment” on page 137 , but set both the
first and last marker point to the value of the point you want to set. For example, if you want to set a marker
on point 5, set both the first and last value to 5.
Placing Repetitively Spaced Markers
The following example sets markers across a range of points and specifies the spacing (skipped points)
between each marker. You must set the spacing
before you apply the marker settings; you cannot apply
skipped points to a previously set range of points.
1. Remove any existing marker points ( page 130 ).
2. In the
Marker Utilities
menu ( page 134 ), press
Set Markers
.
3. Highlight the desired waveform segment.
In ARB formats there is only one file (
AUTOGEN_WAVEFORM
) and it is already highlighted.
4. Highlight the desired marker number: Press
Marker 1 2 3 4
.
5. Set the first sample point in the range (in this example, 5):
Press
Set Marker On Range Of Points
>
First Mkr Point
>
5
>
Enter
.
6. Set the last marker point in the range to a value less than the number of points in the waveform, and
greater than or equal to the first marker point (in this example, 25):
Press
Last Mkr Point
>
25
>
Enter
.
7. Enter the number of sample points that you want skipped (in this example, 1):
Press
# Skipped Points
>
1
>
Enter
.
