<Offset1>, <Offset2>,
<Offset3>
Defines I/Q origin offset values used for calculation of an upper limit for the inband
emissions. Three different values can be set for three TX power ranges, see
ter 3.3.6.4, "Inband Emissions Limits"
Parameters:
<Offset1>
Offset for high TX power range
Range:
-256 dBc to 256 dBc
*RST:
-24.2 dBc
Default unit: dBc
<Offset2>
Offset for intermediate TX power range
Range:
-256 dBc to 256 dBc
*RST:
-19.2 dBc
Default unit: dBc
<Offset3>
Offset for low TX power range
Range:
-256 dBc to 256 dBc
*RST:
-9.2 dBc
Default unit: dBc

<RelativeLevel>,
<AbsoluteLevel>
Defines a relative and absolute limit for the ACLR measured in the adjacent GSM
channel.
Parameters:
<RelativeLevel>
Range:
-256 dB to 256 dB
*RST:
19.2 dB
Default unit: dB
Additional parameters: OFF | ON (disables the limit check | ena-
bles the limit check using the previous/default limit values)
