TECHNICAL APPENDIX
| TECHNICAL APPENDIX 168
In SmartScan Mode the behavior expected is the same of the normal Scanning mode because this parameter is
continuous and always available on the channel.
REPLAY ENABLED TRAPS
The RDS LEVEL alarm trap is replayed with its original status, time and value. Trap Counter is normally incremented.
All data and parameters are available in the MIB L3-5 to set and test this configuration.
PLANNED IMPROVEMENTS
Add in the panel display even the out of range Rds Level value in the list error sequence after the alarm label
“RDS_LEV”
NOTES
Noticed (as already measured and documented by MB) a dependence of the measure from the deviation/power of the
signal. With strong audio compression (over 6.0 dBitubs412) or very high deviation (over 100kHz) the error range can be
: -0.1kHz to +0.4kHz
Testing under low power mpx conditions and normal deviation(power less than 1 dBitubs412, deviation less than 80kHz)
, the loss of precision caused from the deviation/power dependence is typically less than +- 0.2kHz.
On this release the measurement attack time has been reduced to stabilize better the measure.
Acting with very slow attack times and fast releases measure times is possible to improve the long term precision
measurement.
With an attack time of some minutes (only for the near 0.5kHz convergence) could be possible have a precision -
0.2kHz on all conditions filtering the positive error tendency.
