Gap Channel Bandwidths ← Gap Channel Definition
The gap channel bandwidth is normally predefined by the transmission technology
standard. The correct bandwidth is set automatically for the selected technology. The
bandwidth for each channel is indicated by a colored bar in the display (if the gap is not
too narrow, see
"Channel display for MSR signals"
Remote command:
[SENSe:]POWer:ACHannel:BANDwidth:GAP<gap>
Weighting Filters ← Gap Channel Definition
Weighting filters allow you to determine the influence of individual channels on the total
measurement result. For each channel, you can activate or deactivate the use of the
weighting filter and define an individual weighting factor ( "Alpha:" value).
Remote command:
[SENSe:]POWer:ACHannel:FILTer[:STATe]:GAP<gap>
[SENSe:]POWer:ACHannel:FILTer:ALPHa:GAP<gap>
Limit Checking ← Gap Channel Definition
During an ACLR measurement, the power values can be checked whether they
exceed user-defined or standard-defined limits. A relative or absolute limit can be
defined, or both, for each individual gap channel. Both limit types are considered,
regardless whether the measured levels are absolute or relative values. The check of
both limit values can be activated independently. Furthermore, relative limits can be
defined and activated individually for ACLR or CACLR power levels.
If any active limit value is exceeded, the measured value is displayed in red and
marked by a preceding asterisk in the result table.
Note that in addition to activating limit checking for individual channels, limit checking
must also be activated globally for the MSR ACLR measurement (see
Remote command:
CALCulate<n>:LIMit<li>:ACPower[:STATe]
