Freq Error
Freq Error displays the frequency difference of the received DMR transmission carrier minus the R8100
Monitor Frequency.
Note: For other standard RF Zone settings see RF Zone / Monitor Mode.
2.2.7.2.3.1 DMR Zone
Count
Increments each time the specified SYNC Pattern is detected, thus the R8100 synchronizes to that TDMA
slot.
Note: Test measurements are only displayed if two consecutive SYNC patterns are detected; this
maximizes the accuracy of the measurement.
Source ID
Displays the Source Identifier (ID) which identifies the individual address of the transmitter. This is
obtained from bytes 7-9 of the Full Link Control message composed by four 32-bit embedded signaling
fields at the center of bursts B to F of a voice superframe. The Source ID is displayed in base 10 and base
16 format
CC
Displays the 4-bit color code (0 to 15) of the synchronized TDMA slot of the received signal transmission.
CC is digital ID information equivalent to CTCSS/PL and CDCSS/DPL of analog FM radio systems.
Symbol Deviation
Displays the symbol deviation estimated by averaging the normalized frequency deviations at symbol
times in the specified burst of the synchronized TDMA slot of the received signal and then scaling by the
maximum symbol value. The normalized frequency deviation is computed as the ratio of the actual
frequency measurement at a given symbol or deviation state by the corresponding symbol value. The ideal
is 1944 Hz.
FSK Error
Displays the percentage computed from the symbols in the specified Burst of the synchronized TDMA
slot of the received signal. The FSK Error is computed relative to the Symbol Deviation measurement.
Magnitude Error
Displays the percentage computed from the symbols in the specified Burst of the synchronized TDMA
slot of the received signal.
BER
Displays the bit error rate percentage of bit differences between the O.153 pattern and the bits of the
synchronized TDMA slot of the received signal. For example, if 13 of the 1296 super frame payload bits
do not match the predefined pattern, the rate will be 1.0030864% (13/1296*100%). Assurance of the
computation may be gained by transmitting a different calibration test pattern (e.g. BER of 1031 Hz vs.
O.153 is 47.299381%).
