The level sweep waveform produces a sine wave which changes amplitude over time. You select the start and stop levels in decibels, the tone frequency, and sweep time. The start level can be less than the stop level in which case the signal level will decrease over time.
The sweep time specifies how long the level takes to change from the start to the stop limits. This value is specified in milliseconds. The sweep will repeat continuously until the generator is stopped.
