Example 9: Pass/Fail Test

The Pass/Fail Test is one of enhanced special functions based on DS1000CA series.

In this test function the oscilloscope, compares the input signal to the established

waveform mask. If the waveform “touches” the mask, a “Fail” signal occurs,

otherwise the test passes. When needed, a programmable output can be used for

external automatic control applications. The output is built in as a standard feature,

and is optically isolated.

Do the steps as following:

1. Press Utility→Pass/Fail.

2. Press Enable Test and select ON.

3. Press Mask Setting→Load.

4. Press Load to recall the saved mask or press X Mask and Y Mask to adjust the

horizontal limit and vertical limit then press Create Mask to create a new mask.

5. Press Output to select the expected outputting waveforms.

6. Press Operate to start the test.
