Equivalent RMS Input Noise:
Equivalent RMS Input Noise is a figure of merit used to
quantify the noise contributed by a system component. It incorporates into a single value,
several factors that influence a noise specification such as signal-to-noise ratio, noise floor, and
system bandwidth. Given a measuring systems sensitivity/scale factor and the level of “white”
noise in the system, Equivalent RMS Input Noise can be expressed using actual measurement
units.
Effective Resolution:
Effective Resolution is an application dependent value determined by
multiplying the Equivalent RMS Input Noise specification by the square root of the measurement
bandwidth.
Example: An application with a 100Hz bandwidth using a KD-5100 with an Equivalent RMS
Input Noise level of 0.2nm/
√
Hz results in a system with an effective resolution of 0.2nm/
√
