Document use is restricted to that described on cover 8-5
synchronization. This will degrade communications throughput by increasing the
amount of time to synchronize to the incoming PN code or by preventing PN code
synchronization altogether. Using this command results in an internal radio receiver
reset condition, which forces a radio receiver resynchronization. The range of
allowable values is 00
16
to FF
16
subject to the above stated requirements.
LOWER THRES W/O PN RESET BDR and MDR
This command is similar to the Set Lower Threshold command except it does not force
the radio receiver to reacquire PN synchronization after the new threshold is loaded.
SET LOWER LOCK THRESHOLD BDR and MDR
The lower threshold value is part of the radio receiver’s confidence test for maintaining
PN code synchronization. The LOWER LOCK THRESHOLD must be less than the
UPPER THRESHOLD and is normally less than the LOWER LOCK thresholds. The
actual values used are set at the factory. Large values for the lower threshold require
input high signal levels. If the levels are set too high, the radio will not be able to
maintain PN synchronization. If the levels are set too low, the radio will falsely maintain
PN synchronization. This will degrade communications throughput by increasing the
amount of time to correctly synchronize to the incoming PN code or by preventing PN
code synchronization altogether. Using this command results in an internal radio
receiver reset condition, which forces a radio receiver resynchronization. The range of
allowable values is 00
16
to FF
16
subject to the above stated requirements.
DISABLE TRANSMITTER BDR and MDR
This command allows the user to manually turn off the radio transmitter.
ENABLE TRANSMITTER BDR and MDR
This command allows the user to manually turn on the radio transmitter. If the radio
has not been powered down, the output level will be the last loaded value. If the radio
is powered down after selecting this command, the output level will be the last value
saved to non volatile memory. The user can check the level with the STATUS
REQUEST command. The user can change the output level with the SET dBm
OUTPUT LEVEL command.
