CALCulate<n>:LIMit<k>:ACPower:ACHannel[:RELative] <LowerLimit>,
<UpperLimit>
This command defines the relative limit of the upper/lower adjacent channel for adja-
cent-channel power measurements. The reference value for the relative limit value is
the measured channel power.
It should be noted that the relative limit value has no effect on the limit check as soon
as it is below the absolute limit value defined with the CALCulate<n>:LIMit<k>:
ACPower:ACHannel:ABSolute command. This mechanism allows automatic check-
ing of the absolute basic values of adjacent-channel power as defined in mobile radio
standards.
Suffix:
<n>
.
Selects the measurement window.
<k> irrelevant
Parameters:
<LowerLimit>,
<UpperLimit>
0 to 100dB; the value for the lower limit must be lower than the
value for the upper limit
*RST: 0 dB
Example:
CALC:LIM:ACP:ACH 30DB, 30DB
Sets the relative limit value for the power in the lower and upper
adjacent channel to 30 dB below the channel power.
CALCulate<n>:LIMit<k>:ACPower:ACHannel[:RELative]:STATe <State>
This command activates the limit check for the relative limit value of the adjacent chan-
nel when adjacent-channel power measurement is performed. Before this command,
the limit check must be activated using CALCulate<n>:LIMit<k>:ACPower[:
STATe].
The result can be queried with CALCulate<n>:LIMit<k>:ACPower:ACHannel:
RESult. Note that a complete measurement must be performed between switching on
the limit check and the result query, since otherwise no correct results are available.
