Command or
Response to
Query
Query only.
Returns the increase in Tx power level, in dB (from the nominal setting) due to the action
of AUPC.
Range is 0.0 to 9.9 dB
Responds x.x if AUPC is disabled.
Example: PLI=2.3
Command or Query.
Tx Clock Source, where:
0=Internal
1=Tx Terrestrial
2= Loop-Timed
Note: When TCK is changed from Internal to Non-Internal, Clock Extension Mode will be
automatically changed to 0=None if it was 1=TxLock. Reply: TCK+
Example: TCK=0 (selects Internal)
Command or Query.
Invert Transmit Data, where:
0=Normal
1=Inverted
Example: TDI=1 (selects Inverted TX Data)
Command or Query.
Tx Frequency, where:
CDM-570L: 950 to 1950 MHz
CDM-570: 50 to 90 and 100 - 180 MHz
Resolution=100 Hz
Example: TFQ=0950.9872
Example: TFQ=0073.4528
Command or Query.
(Command not valid in AUPC mode)
