CALCulate<n>:LIMit<li>:ESPectrum<sb>:MODE <Mode>
Which limit line is to be used for an SEM measurement depends on the power class
the input signal power belongs to. This command defines wether the power class is
determined automatically or manually.
Suffix:
<n>
.
irrelevant
<li> irrelevant
<sb> 1 to 8
Parameters:
<Mode> AUTO
The power class (and thus the limit line) is assigned dynamically
according to the currently measured channel power.
MANUAL
One of the specified power classes is selected manually for the
entire measurement. The selection is made with the
CALCulate<n>:LIMit<li>:ESPectrum<sb>:
PCLass<pc>[:EXCLusive]
command.
*RST: AUTO
Example: CALC:LIM:ESP:MODE AUTO
Activates automatic selection of the limit line.
CALCulate<n>:LIMit<li>:ESPectrum<sb>:VALue <Power>
This command activates the manual limit line selection as and specifies the expected
power as a value. Depending on the entered value, the associated predefined limit
lines is selected.
This command has the same effect as a combination of the
CALC:LIM:ESP:MODE
MAN
and the
CALCulate<n>:LIMit<li>:ESPectrum<sb>:PCLass<pc>[:
EXCLusive]
commands; however, the power class to be used is not defined directly,
but via the expected power. As opposed to
CALC:LIM:ESP:MODE AUTO
, the power
class is not re-assigned to the input signal power dynamically, but only once when the
command is executed.
