The following figure represents how the instrument creates the template waveform limit test
envelope from user-entered vertical and horizontal division units. Division units are referenced to
graticule divisions, where 1 major division contains 1000 millidivisions, or mdivs. The minimum
mdiv unit is 20, which equals one screen pixel.
When a source waveform is compared with an envelope waveform, each source waveform sample
point value is compared to the vertical and horizontal min/max values of the corresponding
envelope waveform sample point. Any source waveform data point that is not equal to or within
the corresponding template envelope min/max values is a violation.
Saving and Recalling Setups
This instrument can save a number of different instrument setups for later recall, limited only by
the space that you have to store the setups.
By saving and recalling different setups, you can switch from setup to setup without having to first
manually record your settings and then manually set them. This capability is helpful when you
want to:
 Save and recall a setup that optimizes the instrument for displaying and analyzing a certain
signal.
 Save a series of setups to help automate a procedure through recall of a sequence of saved
setups as part of performing the procedure.
 Save a setup for sharing with a second instrument.
If you do not have an attached keyboard, you can still name setup files. The Save and Recall
dialog boxes include a pop-up keyboard that you can use with your mouse or the touch screen to
enter the setup path name and file name.
The instrument excludes the following items when saving setups:
 Channel waveforms and reference waveforms. Control settings (scale, position, and so on) are
saved but not the waveform data. Upon recall of the setup, the settings are applied, but the
data is not restored.
 Math waveforms. Control settings and the math expression are retained but not the waveform
data. Upon setup recall, however, the math waveform expressions are applied, but math
waveform data is not restored.
 User options stored in the Windows registry. These include all options set in the User
Preferences control window.
 If you want to save a waveform in a useful format for other applications, such as a
spreadsheet, use the save or save as function (see Saving and Copying Waveform Data on
page 289).
A few other things to remember when saving and recalling setups:
