Figure1: Out–of–range signal Figure 2: Signal brought into range by analog offset Analog offset Also called DC offset, this is a valuable feature available on many PicoScope oscilloscopes. When used correctly, it can give you back the vertical resolution that would otherwise be lost when measuring small signals. Analog offset adds a DC voltage to the input signal. If the signal is out of range of the scope’s analog-to-digital converter (ADC), the offset can be used to bring the signal back in range allowing a more sensitive range to be used.
