# Generation of telemetry displays, which may be tabular,take graphicalthe form of tables, ([[Plot (graphics)|plots]] of parameters against each other or over time), or synoptic displays (interface-orientedsometimes graphicscalled mimics) that graphically present the interfaces between components or subsystems.{{r|Fortescue-GS}}{{rp|484}}

A spacecraft [[database]] provided by the spacecraft manufacturer is called on to provide information on telemetry frame formatting, the positions and frequencies of parameters within frames, and their associated mnemonics, calibrations, and soft and hard limits.{{r|Fortescue-GS}}{{rp|486}} The contents of this database—especially calibrations and limits—may be updated periodically to maintain consistency with onboard software and operating procedures; these can change during the life of a mission in response to [[upgrade]]s, hardware degradation in the [[space environment]], and changes to mission parameters.{{r|Fortescue-Telecom}}{{rp|399}}
