Pass/Fail Testing

Pass/Fail testing is a type of mask testing that is particularly useful for comparing newly acquired signals

to a previously acquired "golden standard" waveform.

Note: Pass/Fail testing does not work with Sequence Mode acquisitions.

A mask defines an area of the grid against which a source Channel, Zoom, or Math trace is compared.

Test conditions are associated with the mask, defining how the waveform is to be compared to the

masked area (e.g., some/all values fall within, some/all values fall outside), and a pass or fail result is

returned indicating the condition was found to be true or false.

Mask testing can be done using a pre-defined mask or a mask created from a waveform with user-defined

vertical and horizontal tolerances.

Access Mask Test Dialogs

Choose Analysis > Pass/Fail Setup to display the Pass/Fail dialog. To the right are the Load Mask and

Make Mask subdialogs where you make and manage masks.

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.

1. Open the Load Mask subdialog.

2. To use a saved .msk file, touch File and select the mask.
