Dynamic Range

A dynamic range measurement quantifies the distortion and noise found in the device under test (DUT) output when a low-level signal is provided.

Typically, the dynamic range is measured with the amplitude of the excitation signal set to –60 dB FS, where FS is the DUT input channel full-scale amplitude. Use the following equation to calculate a dynamic range.

DR = F ∑   P N o i s e + ∑   P H a r m o n i c s

The following figure shows the connection scheme for a dynamic range measurement.
