Waveform Save Menu
Waveform Save Menu
A waveform memory consists of a single waveform record, including the
horizontal and vertical scaling parameters. The scaling parameters allow
measurements on previously stored waveform and function data. Also, you
can set the x and y markers on stored waveforms when they are displayed on
the screen.
When the oscilloscope is in the envelope display mode and a waveform store
is executed, the minimum value and maximum value are stored separately.
The maximum value is stored in m1 if ml or m2 are the selected store
locations, or in m3 if m3 or m4 are the storage locations. The minimum
values are stored in m2 or m4 respectively. A message is displayed above the
waveform display area indicating the storage locations of both values.
Nonvolatile Softkey
The nonvolatile softkey lets you select which memory to use. The
selections are nonvolatile memories m1, m2, m3 and m4. When a memory is
turned on, the small circle below the label is highlighted. When the memory
is protected, the small circle has an "x" through it. The waveform memories
are record memories that store up to 32K points in the real-time mode or 500
points in the repetitive mode.
Display Softkey
The display softkey toggles the selected waveform memory display on or
off. When on is selected, the time base delay softkey is displayed that
shows the time base and delay settings when the waveform was stored. You
can use the show menu to see the vertical and trigger settings.
