Description of Arguments
Command or Query.
Tx Power Level in the form sxx.x, where:
s = sign [– (negative) or + (positive)]
xx.x: power value
Tx Output power level for 950 to 1950MHz range is between -5 and
-40 dBm.
Tx Output power level for 50 to 180MHz range is between -5 and -25
dBm.
Example: TPL=-13.4
Command or Query.

0=Off
1=Normal (default)
2=IESS-315 when in Turbo mode
Example: TSC=2 (Scrambler On)
Command or Query.
