This topic is only valid for instruments with the Fast Eye Mask option. See the User
Guide for a description of the available options for your instrument.
The Fast Eye Mask measurement is first of all meant for production and screening
tests. It allows to determine very quickly whether the eye opening seen at the
output signal of a device is within specifications, that is, within certain timing and
voltage limits.
The following topics inform you on how you can programmatically set up Fast Eye
Mask measurements.
See the online Help or the User's Guide for details on working with the Fast Eye
Mask.
To be able to set up and run a Fast Eye Mask measurement using SCPI, you should
be aware that the Fast Eye Mask measurement is programmatically implemented
as an object on the instrument. You must first create an instance of the object, and
then use the handle returned to address this object.
As good programming practice, also be sure to close the object when you are
finished with your test.
