About This Product
Focus, brilliance, X shift and Y shift controls set the position and nature of the trace. At the slowest time base setting the spot takes 10 s to cross the screen, which suits slow analogue computing investigations. With the time base switched off, the X input p.d. controls the horizontal position of the spot, for example to display Lissajous figures. A student audio signal generator is not included.
Frequently Asked Questions
Q1. Why does the trace take a moment to settle after moving it? The start of the spot is synchronised automatically to the positive-going edge of the Y input, so the trace may take about 1 s to settle if the Y position is altered.
