Averaging
Averaging is a mathematical process to reduce the variation in a measurement by summing the data points from multiple measurements and dividing by the number of points summed.

Fall Time
Fall time is the time required for the amplitude of a pulse to decrease (fall) from a specified value (usually 90 percent of the peak value exclusive of overshoot or undershoot) to another specified value (usually 10 percent of the maximum value exclusive of overshoot or undershoot).

Noise Density
Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.

Resolution Bandwidth (RBW)
Resolution Bandwidth (RBW) is the minimum bandwidth over which you can separate two signals and still see them.
