Behavior. Entering a number in the Number of Waveforms (Samples) entry box stops the test when that number has been
reached.
If the waveforms or samples that fail are equal to or greater than the number in the Fail Threshold entry box, the test has failed. If
the failed waveforms or samples are less than the number in the Fail Threshold entry box, the test passes.
The instrument begins sampling after the number of seconds has passed set in the Pre-Test Delay entry box. Use the Test Delay
if you need to give the signal source time to stabilize.

NOTE. This feature is not available on MSO/DPO5000B Series instruments.
Your instrument is shipped with an internal speaker that some of the software features use to send an audible alert to the user.
To enable this speaker, the sound card in your instrument must be turned off. With the sound card off, you will not have access to
standard Windows audio features, such as the ability to listen to a music CD.
If you turn the sound card on, the internal speaker is disabled. You will need to connect headphones or an amplified speaker to
the headphone jack on the instrument to hear the alerts.
