Ramp Modulation Type (Phase, Slope)
Controls: Gen Dlg >> Stream >> Wave >> Ramp >> Modulation
When a Ramp wave is active, you can change the normal Phase Modulation to allow Slope modulation instead. This pair of radio buttons selects the way the modulation will operate if it is used; it doesn't activate the modulation directly. With Phase Modulation the waveform simply slides back and forth, whereas Slope Modulation effectively modulates the Rise value. If you set Rise to 50% you get a triangle wave, and with Slope Modulation this tilts to the right and left. At 100% modulation, the wave smoothly changes between an effective Rise of 0% and 100%. This effect is easier to see at lower frequencies, where there are only a few cycles on the trace. Macro Notes: L.1.RampMod=Phase sets Left Stream 1 Ramp Modulation Type to Phase, L.1.RampMod=Slope sets it to Slope. See also Ramp Wave, Wave Dialog |
