Format
The le F ormat softkey determines the format that is used to store waveforms
to a disk. The three waveform le formats are internal, text verbose , and text
Y values . The two mask le formats are mask only , and mask and setup .
When a text le is loaded into the instrument, it is placed into one of the four
waveform memories by overwriting any data that was previously stored in
that waveform memory .

Internal The internal format is a binary le format, which if you try to read it in a
word processing program, it will give you meaningless information. However ,
this is the preferred waveform-storage method because the les take up
one-third as much disk space as text les . Y ou can always convert them to
text les at a later date . Internal format les have a .W A V le extension.
W aveform les stored using the internal format contain the vertical and
horizontal scaling parameters of the original waveform. Therefore , you
can go into the W aveform menu and turn on the display for the waveform
memory that the le was loaded into . Then, you can perform measurements
on the waveform, compare it to other waveforms , rescale it vertically and
horizontally , or use it as a function operand.
