Make Mask
Use this procedure to create a new mask based on a live waveform. The mask covers the area of the
waveform plus the boundaries you enter.
1. Open the
Make Mask
subdialog.
2. If desired, enter a new
Destination File Name
and path, or touch Browse and select a previous
file to overwrite. The file name should end with the
.msk
extension.
3. Touch the
Ver Delta
and
Hor Delta
fields and enter boundary values using the pop-up Virtual
Keypad or the front panel Adjust knob.
4. Touch
Make from Trace
.
Load Mask
Use this procedure in lieu of Make Mask if you have a pre-defined mask file, or wish to recall a mask
you previously created and saved.
1. Open the
Load Mask
subdialog.
2. To use a saved .msk file, touch
File
and select the mask.
To use an industry standard mask, touch
Standard
and select the mask from the pop-up.
3. Check
View Mask
to display the mask over the trace.
Remove a Mask from the Display
Touch the
Delete All Masks
button. Alternatively, open the
Q
x
dialog where a particular mask is set,
and on the
Load Mask
subdialog, touch
Delete
.
Set Gates
Set gates to limit the portion of the waveform that is compared to the mask.
1. Open the
Gate
subdialog.
2. Enter the
Start
and
Stop
horizontal divisions that mark the segment of the waveform to be
tested with this mask. This can be a whole division or a fraction of a division. Divisions are
numbered 1-
n
left to right.
A quick way to position the gate is to drag the gate posts initially placed at the extreme left
and right ends of the grid to the desired points.
Define "True"
1. Open the
Test
subdialog.
2. Select one of the conditions that, when True (yes), results in a Pass.
3. Optionally, turn
Off/On
markers. Markers visually indicate where on the waveform mask
violations have occurred.
