2 Oscilloscope Familiarization Labs

In addition to stopping acquisitions when an error is detected as shown in

Figure 21, you can also save a waveform, save an image, print, or perform

specific measurements when an error is detected. Using the “Run Until”

selection, you can also set up mask testing to run for a specific number of

tests, minimum time, or minimum Sigma test criteria. Note that in

addition to creating a pass/fail mask using the auto- mask creation feature

as demonstrated in this lab, you can also import a mask based on industry

specifications, such as an eye- diagram mask, from a USB memory device.

These types of imported masks can be easily created within a standard

text editor, such as Notepad on your PC.
