The inherent
residual responses
These are discrete responses seen on an analyzer display although no input signal is applied.
resolution
Refer to frequency resolution
resolution bandwidth
The ability of an analyzer to display adjacent responses discretely (hertz, hertz decibel down). This term is used to identify the width of the resolution bandwidth filter of an analyzer at some level below the minimum
For digital displays, this is the display detection mode in which the value displayed at each point on a trace is based upon whether or not the video signal both rose and fell during the frequency or time interval represented by the point. If the video signal only rose or only fell, the maximum value is displayed. If the video signal both rose and fell, the maximum value during the interval is displayed by
sample
The instantaneous value of an incoming signal. On digital displays, each displayed point of the signal indicates the instantaneous value of the signal for that part of the frequency span or time interval represented by the point.
