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.

The less strict (higher) limit line is displayed

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 268.

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 275). 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 267).
