The Cambridge 6210 takes a different approach. It power limits only part of the X-axis scanner's signals. Testing for ringing and overshoot About square wave tests Square waves are important to test how fast a scanner can move from point to point. The square wave shown here is a large-angle test. This capability is important for images where the scanner must jump large distances as fast as possible.
Examples are abstracts, rasters, and star fields.
It is possible to eliminate overshoot by adding steps to large jumps, essentially converting them to a series of small jumps. But this works by slowing down the scanner, which can defeat the purpose of jumping far and fast. The Pangolin TrueK 50 and Cambridge 6210 both speed up small steps, while leaving large steps essentially unchanged. A key question is whether the small-step speedup balances out the extra steps added to slow down large jumps. T hese final pictures show a square wave test pattern at around 30 degrees.
