RSSI Gain Step

The input amplitude span between taps of the RSSI (received

signal strength) attenuator ladder. Ideally each stage should

span 6 dB of input power.

RSSI Hysteresis

The amount of movement in the RSSI switch points, depending

on the direction of approach. Hysteresis prevents unnecessary

RSSI toggling when input signal power is near a threshold.

Signal-to-Noise Ratio (Without Harmonics)

The ratio of the rms signal amplitude (set at 1 dB below full

scale) to the rms value of the sum of all other spectral compo-

nents, excluding the first five harmonics and dc.

Worst Other Spur

The ratio of the rms signal amplitude to the rms value of the

worst spurious component (excluding the second and third

harmonic) reported in dBc.
