On
Includes all detected peaks (up to a maximum defined by "Peaks per Range").
Off
Includes only one peak per range.
Peaks per Range
Defines the maximum number of peaks per range that are stored in the list. Once the
selected number of peaks has been reached, the peak search is stopped in the current
range and continued in the next range. The maximum value is 50.
Remote command:
Saving the Evaluation List
Exports the evaluation list of the Spurious Emissions measurement to an ASCII file for
evaluation in an external application. If necessary, change the decimal separator for
evaluation in other languages.
Define the file name and storage location in the file selection dialog box that is dis-
played when you select the "Save" function.

5.7.5 How to Perform a Spurious Emissions Measurement
1. Press the MEAS key, then select the "Spurious Emissions" measurement.
2. Define the span of the signal to be monitored in the general span settings.
3. Select the "Overview" softkey, then select the "Spurious Setup" button.
The "Spurious Emissions" dialog box is displayed.
4. Split the frequency span of the measurement into ranges for signal parts with simi-
lar characteristics.
Define the required ranges in the "Sweep List" using the "Insert before Range" and
"Insert after Range" buttons, which refer to the currently selected range.
5. Define the measurement parameters for each range as required.
6. Optionally, define a limit check.
a) Activate the limit check by setting "Limit Check" to "Absolute". The limit check
is always activated or deactivated for all ranges simultaneously.
b) Define the limit line's start and stop values for each range of the signal. If a sig-
nal level higher than the defined limit is measured, the limit check fails, which
may indicate a spurious emission.
7. Configure the peak detection during a Spurious Emissions measurement: select
the "Evaluations" button in the "Overview".
