5.1 P+ — Plot Test Pattern
The RVP900 can produce a simple test pattern to verify that the display
software is working properly. From the TTY monitor enter the P+
command. This prints the message Plotting Test Pattern... on the TTY
and then produce the plot shown in Figure 25 on page 140
This display is actually an overlay of six different strokes:
- Bottom line
- Middle line
- Top line
- Line sloping up
- Line sloping down
- Sine wave pattern
The later changes phase with each plot so that, with a little imagination, it
appears to be radiating from the left side of the display.

When you are satisfied that the plot is being drawn correctly, type Q or
press ESC to return to the TTY monitor.
