The limit check is considered to be "failed" if any signal level outside the absolute limits
is measured.
In addition to the limit line itself, the largest deviations of the absolute power from the
limit line for each range are displayed in the evaluation list if the limit check is activa-
ted. Values that exceed the limit are indicated in red and by an asterisk (*).
Although a margin functionality is not available for the limit check, a margin (threshold)
for the peak values to be displayed in the evaluation list can be defined in the list eval-
uation settings. Furthermore, you can define how many peaks per range are listed. For
details see
chapter 5.7.4.3, "List Evaluation" , on page 246.
5.7.4 Spurious Emissions Measurement Configuration
Spurious emissions measurements are selected via the "Spurious Emissions" button in
the "Select Measurement" dialog box. The measurement is started immediately with
the default settings. It can be configured via the MEAS CONFIG key or in the "Spurious
Emissions" dialog box, which is displayed when you select the "Spurious Setup" button
in the "Overview" or the "Sweep List" softkey from the "Spurious Emissions" menu.
For details on using the configuration "Overview", see chapter 6.1, "Configuration
Overview" , on page 312.
The remote commands required to perform these tasks are described in chap-
ter 11.5.7, "Measuring Spurious Emissions" , on page 765.
The following settings are available in individual tabs of the "Spurious Emissions" con-
figuration dialog box, or via softkeys in the "SpurEm" menu.
● Sweep List .............................................................................................................242
● Adjusting the X-Axis to the Range Definitions .......................................................246
● List Evaluation .......................................................................................................246
5.7.4.1 Sweep List
For Spurious Emissions measurements, the input signal is split into several frequency
ranges which are swept individually and for which different limitations apply. In the
"Sweep List" dialog box you configure the individual frequency ranges and limits.
If you edit the sweep list, always follow the rules and consider the limitations described
in
chapter 5.7.3.1, "Ranges and Range Settings" , on page 240.
