Constellation (Meter Zone selection)
The Constellation display provides a visual representation of overall transmitter operation – see Figure
3.2.8.3.1-2. DMR radios broadcast voice and data using 4 frequency shift deviations of the carrier to
represent symbols containing 2 data bits. Four red tick marks on the display represent the expected
locations for the deviation states when the radio is transmitting data bit symbols using the modulation.
White bars show the actual deviation measurement at symbol decision times. A tighter grouping around
the red tick marks indicates more accurate transmitter performance.
