Tx Alpha TXA= 1 byte, value of 0
thru 5
Description of Arguments
Command or Query.
Tx Output power level between 0 and -40 dBm (minus sign assumed) for 950 to 1950MHz range.
Tx Output power level between 0 and -25 dBm (minus sign assumed) for 50 to 180MHz range.
Example: TPL=13.4
In AUPC mode, command is not valid. Response will be TPL*.
When APC is active, query returns "TPL=99.9"; when command is not valid, response will be TPL*.
When the external 20 dB attenuator is activated (via AUP), the permitted power level range shifted down by 20dB.
Example: –65 and -20 dBm.
600 Emulation:
Level range: 0 to -20 dBm (minus sign assumed).
600L Emulation:
Level range: 0 to -45 dBm (minus sign assumed).
Command or Query.
Tx Carrier State in the form x, where:
0=OFF due to front panel or remote control command
1=ON
2=RTI (receive/transmit inhibit), timeout = 10 seconds
3=OFF due to ext H/W Tx Carrier- Off control
4=OFF due to BUC or High-Stability Ref warm-up
5= Carrier controlled by STDMA Controller
6=RTI (receive/transmit inhibit), timeout = 1 second
7=RTI (receive/transmit inhibit), timeout = 2 seconds
8=RTI (receive/transmit inhibit), timeout = 4 seconds
9=RTI (receive/transmit inhibit), timeout = 7 seconds
Note: arguments indicated with a * are status-only. They are not valid as a command, and are not indicated in MGC?
response.
Example: TXO=1 (Tx Carrier ON)
Command or Query.
Tx Filter Rolloff Factor in the form x, where:
0= 0.35
1= 0.25
2= 0.20
3= 0.15
4= 0.10
5= 0.05
Example: TXA=0 (Tx filter rolloff factor is 0.35)
