To start waveform monitoring

Before using a testing mask to monitor a waveform, the mask must be

created. Once created, the mask is automatically stored in one of the two

nonvolatile mask memories. Procedures for creating a mask template are

provided in this chapter.

2 Press the Mask Test softkey.

3 Press the Use Mask softkey to select the previously created mask

number (1 or 2).

4 Press the Test Options softkey.

A softkey menu with six softkey choices appears. Five of them are related to

the mask testing functions.

Fail When – In or Out Selects if a test failure occurs when the signal moves

out of, or in to the mask template.

•

On Fail - Stop or Run Used to select what state the oscilloscope will be in

after a test violation has occurred.

When stop is selected, the current acquisitions stop when the first

violation of the mask occurs. The test can be restarted by pressing

the RUN key.

When run is selected, the oscilloscope continues to acquire data

and display the most recent trace.

•

Auto Save – Off or On Used to select if a test violation waveform is

recorded. When On is selected, an additional softkey appears. See

"Automatically Saving Test Violations" later in this chapter for more

information.
