The unit of measure is the lumen per steradian, or candela (cd). (The steradian is the unit of measurement of a solid angle.) The Intensity control on an oscilloscope adjusts the magnitude of the luminous intensity and, consequently, the luminance and the brightness of the light output. ... (In SI units, 1 lux on the...
