To Memory The T o Memory softkey selects which of the available memory locations the
instrument saves the waveform to . Pressing the T o Memory softkey toggles
among the nonvolatile memory locations .
When a waveform is saved to a memory , it overwrites any data that was
previously stored in that memory . All pulse measurements or functions using
that memory location are recalculated. If the waveform display is on, then
the display is also updated.
W aveform memories are nonvolatile so the data is not lost if you press
A utoscale , turn o the power , or set the instrument to the default settings .
A waveform memory contains a single waveform record, including the
horizontal and vertical scaling parameters . Therefore , you can make
parametric measurements on stored waveforms or use them as operands in a
function. Y ou can also recall the waveform for future comparison or analysis ,
print it, save it to a disk, or load it from a disk.
It takes less time to store and recall data to waveform memories than to store
the same data to the disk drive . Therefore , you may nd it more convenient
to use the four waveform memories for storing data temporarily , and the disk
drive for storing data permanently .

Save The Save softkey copies the selected waveform to the selected memory . If
you are saving a persistence trace to a waveform memory , only the last
waveform record is saved to that memory . That is because waveform
memories store only single-valued, time-ordered data, and persistence traces
are multivalued sets of data. Use the pixel memory to store persistence
traces .
