 Recalling a setup replaces the current setup with the recalled setup. If you do not want to lose
your current setup, save the setup file for later recall.
 Saved setups may contain settings inappropriate for waveforms currently in your instrument.
For example, if you save a setup that displays a math waveform that is the average of
reference waveform 1, when you recall the setup, if the reference is empty, the math and
reference waveforms are not displayed.
Saving and Recalling Waveforms
This instrument can save any number of waveforms, limited only by the space that you have to
store them.
By saving a waveform, you can recall it at a later time for comparison, evaluation, and
documentation. This is helpful when you want to:
 Recall a waveform for further evaluation or comparison with other waveforms.
 Extend the waveform carrying capacity of the instrument. The instrument supports four
reference, four channel, and four math waveforms. If you want more than four reference
waveforms, you can save additional references to disk for recall later.
The Reference Setup control window contains a Label field for including comments with your
saved waveforms.
If you do not have an attached keyboard, you can still enter comments and name reference
waveform files. The Reference Setup control window includes a pop-up keyboard that you can use
with your mouse or the touch screen to enter the waveform path name, file name, and comments.
The instrument recalls each waveform into one of the reference waveform locations (Ref1-Ref4).
You cannot recall into a channel or a math waveform.
Saving and Copying Waveform Data
This instrument supports saving waveform data to a file. The instrument can save waveforms,
images, and measurements in several formats. You can also copy waveform data to the Windows
clipboard for use with other applications, such as spreadsheets or math analysis applications.
A few things to remember when saving waveform data:
 Waveform data are saved as a series of comma-separated values (CSV), which are amplitudes
without units. There is no timing information, but data is placed in the file in sequence from
the first sample in the waveform record to the last.
 Because the waveform data are saved as CSV, without timing and scaling information, the
instrument does not save these waveforms directly. (It only saves the data.) If you intend to
recall a waveform later, save it (see the procedure Saving A Waveform on page 346) using
file type .wfm.
 You may also choose to copy a waveform and paste it directly into an application such as
Microsoft Word or Excel. If so, select your waveform, and then select Copy in the Edit menu.
File Formats
To make saved files more useful, select a file format usable by your analysis tools:
Numeric creates files (.txt) in a numeric format usable by text and word processors.
Text creates files (.txt) in a text format usable by text and word processors.
