Waveform Save Menu
Pixel Menu
Volatile Softkey
The volatile softkey selects between pixel memories 1 or 2. The pixel
memories are complete pixel saves of the waveform area (excluding the
graticule and markers) in volatile memory. Data stored to a volatile memory
is lost when the power is cycled.
The entire 256 by 500 point display area is saved in pixel memory.
Therefore, data is mapped directly onto the display and displayed in
half-bright. Because the pixel memories do not contain any scaling
parameters, there are no measurement capabilities on pixel memories.
Pixel memories are additive. If new data occurs in the same pixel as old data,
the new data overwrites the old data.
Display Softkey
The display softkey toggles the selected pixel memories on or off.
Clear Memory Softkey
The clear memory softkey purges all data from the selected pixel memory.
Add to Memory Softkey
The add to memory softkey adds the currently displayed screen to the
specified pixel memory.
