Pixel
There is one pixel memory, but you can save several waveforms to that pixel
memory. Saving to the pixel memory is like taking a picture of the graticule
area. It is a bitmap of the graticule area, and the horizontal and vertical
parameters are not saved.
The pixel memory is volatile, so turning off the oscilloscope clears the pixel
memory. However, setting the oscilloscope to the default instrument setups
does not clear the pixel memory.
Gray-scale persistence information is not saved to a pixel memory.
You can save several waveforms to the pixel memory, and each waveform can
have different time base and channel scale factors.
Display
Display turns on and off the pixel memory. When the pixel display and the
channel display are both on, the oscilloscope displays any trace overlap in a
different color. The default color is pink; however, you can change the
default color in the display menu.
Add to memory
Add to memory places additional snapshots of the graticule area in the pixel
memory without overwriting any previously stored data. By using the
channel offset to move signals vertically on the display, you can a create a
timing diagram by saving multiple screen snapshots to the pixel memory.
Then, you can save the timing diagram to a disk or you can print it.
Clear memory
Clear memory erases any data stored in the pixel memory.
