6 - Using Slew Rates to Generate Waveforms

As shown in the previous examples there are a number of ways that you can generate custom waveforms. Programmable slew rates provide additional flexibility when customizing waveforms. The following figure illustrates how programmable slew rates are applied in the transient operating modes.

In example ￿, an immediate slew rate of 50 volts/second is used whenever a new output voltage is programmed. In example , a triggered slew rate of 50 volts/second steps the voltage level to its new value. 50 volts/second becomes the new immediate slew rate in step mode. In example , a triggered slew rate of 50 volts/second is used at the start of the pulse. The immediate slew rate of infinity applies at the trailing edge of the pulse. In example , the slew rates are set by the values in the voltage slew list.
