|An instrument for measuring and graphically displaying varying signal voltages. They can can plot a changing electrical signal over time, and then analyze it for properties including frequency, wavelength, and amplitude. Our oscilloscopes have four channels, meaning they can display four signals at once. | |An instrument for measuring and graphically displaying varying signal voltages.
