detector mode
The manner in which analog, video information is processed prior to being digitized and stored in memory. Refer also to negative peak, positive peak,
digital display
A display that uses vectors drawn between a series of data points (analog video) that are first digitized and stored in memory, then displayed. The number of stored data points is a function of the particular analyzer. The displayed information is refreshed (old data points are replaced with new data points stored in memory) at a
display dynamic range
The maximum dynamic range over which both the larger and smaller signal can be viewed simultaneously on the display. For analyzers with a maximum logarithmic display of 10 dB/division, the actual dynamic range may be greater than the display dynamic range. Refer also to dynamic range.
display fidelity
The measurement uncertainty of relative differences in amplitude on an analyzer. On purely analog analyzers (those analyzers that display trace information immediately and do not store, then recall the data to the screen), these differences are displayed on the screen and the graticule is used to evaluate the measurement. Many analyzers with digital displays (refer to digital display) have markers that can be used to measure the signal. As a result, measurement differences are stored in memory, and the ambiguity of the display is eliminated from the measurement.
display range
The calibrated range of the display for a particular display mode or scale factor. Refer also to linear display, log display, and scale factor.
