MS-250 Mixed Signal Oscilloscope Option

Analog Pattern

1. To add the analog pattern to the digital pattern, leave your digital pattern as is and

skip to step 2.

To create an analog-only pattern, touch Set All To... and select Don't Care. This will

eliminate any meaningful digital pattern and activate all the Boolean operators.

2. Touch the Left Arrow button until the C1-EXT group of inputs is displayed in the main

section of the dialog.

3. Touch the Cx button for each input to be included in the pattern, and select whether it

must be High or Low compared to the threshold Level you will set.

Depending on your selection, a logical 1 (High) or 0 (Low) now appears on the dialog.

Leave Don't Care ("X") selected for any input you wish to exclude.

4. Select the Boolean operator (AND, NAND, OR, or NOR) that describes the relationship

among inputs (e.g., C1 must be High AND C2 must be Low).

NOTE:Only the AND operator is available when combining analog and digital patterns.

In the example above, all digital lines have been set to Don't Care ("X"), so all operators

are available.

5. Open the Levels dialog and enter the voltage threshold for each input included in the

trigger.

6. If you've included EXT as an input, open the Ext dialog and enter the Attenuation.
