Limit check type Pass/fail criteria Indicated limit line
Abs and Rel Only if the power exceeds both the
absolute and the relative limits, the
check fails.

for each range.
Abs or Rel If the power exceeds either the
absolute or the relative limits, the
check fails.
The stricter (lower) limit line is displayed for
each range.
The largest deviations of the power from the limit line for each range are displayed in
the evaluation list. Furthermore, the absolute powers for those values, as well as the
relative deviation from the TX channel power are displayed. 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. For details see
"Result Evaluation" on page 244.
Provided XML Files for the Spectrum Emission Mask Measurement
You can change the settings manually or via XML files. The XML files offer a quick way
to change the configuration. A set of ready-made XML files for different standards is
already provided. For details see
Table 6-1 . You can also create and use your own
XML files (for details see "Format Description of Spectrum Emission Mask XML Files"
on page 251). All XML files are stored under "
C:\r_s\instr\sem_std
". Use the
"Load Standard" softkey for quick access to the available XML files (see "Load Stan-
dard" on page 243).
