Used Power Classes:
Defines which power classes are considered for the SEM measurement. Limits can be
defined only for used power classes. It is only possible to select either one specific
power class or all the defined power classes.
If "All" is selected, the power class that corresponds to the currently measured power
in the reference range is used for monitoring. The limits assigned to that power class
are applied (see "Abs Limit Start / Stop <n>" on page 254 and "Rel Limit Start / Stop
<n>" on page 254).
Remote command:
CALCulate<n>:LIMit<li>:ESPectrum<sb>:PCLass<pc>[:EXCLusive]
on page 940
To define all limits in one step:
CALCulate<n>:LIMit<li>:ESPectrum<sb>:PCLass<pc>:LIMit[:STATe]
on page 940
PMin/ PMax
Defines the power limits for each power class. The first range always starts at -200
dBm (-INF) and the last range always stops at 200 dBm (+INF). These fields cannot be
modified. If more than one power class is defined, the value of "PMin" must be equal to
the value of "PMax" of the previous power class and vice versa.
Note that the power level can be equal to the lower limit(s), but must be lower than the
upper limit(s):
P
min
≦P<P
max
Otherwise the ranges are corrected automatically.
Remote command:
CALCulate<n>:LIMit<li>:ESPectrum<sb>:PCLass<pc>:MINimum

CALCulate<n>:LIMit<li>:ESPectrum<sb>:PCLass<pc>:MAXimum
on page 941
Sweep List
Switches to the "Sweep List" tab of the "Spectrum Emission Mask" dialog box and
focuses the "Limit Check" setting for the corresponding power class (1-4) in the refer-
ence range (see "Limit Check <n>" on page 254).
Adding or Removing a Power Class
Adds a new power class at the end of the list or removes the last power class. After
adding or removing, the last power class is adapted to end at "+INF". Note that a maxi-
mum of four power classes are available.
