Example: Spurious Emission
The Japanese Radio Law governing measurement of spurious
specifies searching for the peak level in the swept frequency
segment using different parameter settings and then
performing zero-span measurement of the found peak point.
The MS2830A spurious measurement function not only
performs the sweep search but also performs the zero-span
measurement automatically as well, and displays the results of
both. Using zero-span measurement, the search screen is
displayed as is while zero-span measurement runs in the
background and the result markers are plotted on the search
screen. Time wasted by screen switching is reduced and the
correlation with the search results can be seen at a glance.

Burst Average Power
The average power for the range specified by two markers is
displayed in the time domain. Measurement only requires setting
the measurement start and stop positions on the screen. True
performance is measured using the noise cancellation function to
subtract main-frame noise from the measurement result.
Pre-installed templates for each standard support easy parameter
setting.

Spectrum Emission Mask
This function splits the offset part into up to 12 segments; the
measurement parameters and limit lines can be specified to
measure the peak power and margin for each segment. The results
are tabulated below the trace and marked PASS/FAIL. Pre-installed
templates for each standard support easy parameter setting.
SPA
Spurious Emission
This function splits the frequency range into up to 20 segments for
sweeping; the measurement parameters and limit lines can be
specified to measure the peak power and margin for each segment.
The results are tabulated below the trace and marked PASS/FAIL.
In particular, all tests can be completed up to the final stage without
an external PC because the zero-span capture function described
in the technology compliance test is built-in.
