To edit the mask to test only a portion of a waveform

In certain testing, not all of the points on the waveform need to be tested.

Only the area of interest needs to be tested. For example, to test the amount

of overshoot of a pulse, you only need to test the portion of the waveform

after the rising edge. By reducing the testing area, you can speed up the

testing. You can select the test region by editing the shape of the mask

template.

1 Press Print/Utility twice.

2 Press the Sequence Admin softkey.

3 Press the Mask Editor softkey.

4 Press the Edit Mask softkey, or turn the channel 1 position knob, to

specify the mask that you want to edit.

5 Toggle the Edit Line softkey to select the limit line that you want to

edit.

6 Turn the Delay knob to move the cursor to the starting location that

you do not want to test.

7 Turn the knob closest to the Cursors key to move the voltage cursor

until it reads Don’t Care.

8 Press the Mark softkey.

9 Turn the Delay knob to move the cursor to the ending location of the

region that you do not want to test.

10 Turn the knob closest to the Cursors key to move the voltage cursor

until it reads Don’t Care.

11 Press the Connect softkey.

This region of this particular limit line is not tested during mask testing.
