The changes of the sweep list are only kept until you load another parameter set (by
pressing PRESET or by loading an XML file). If you want a parameter set to be availa-
ble permanently, create an XML file for this configuration (for details refer to "Format
Description of Spectrum Emission Mask XML Files" on page 275).
If you load one of the provided XML files ("Load Standard" softkey, see "Load Stan-
dard" on page 267), the sweep list contains ranges and parameters according to the
selected standard. For further details refer also to "Provided XML Files for the Spec-
trum Emission Mask Measurement" on page 272.
Note: If you edit the sweep list, always follow the rules and consider the limitations
described in "Ranges and Range Settings" on page 269.
Range Start / Range Stop ← Sweep List dialog box ← Sweep List ← Spectrum
Emission Mask
Sets the start frequency/stop frequency of the selected range. Follow the rules descri-
bed in "Ranges and Range Settings" on page 269.
In order to change the start/stop frequency of the first/last range, select the appropriate
span with the SPAN key. If you set a span that is smaller than the overall span of the
ranges, the measurement includes only the ranges that lie within the defined span and
have a minimum span of 20 Hz. The first and last ranges are adapted to the given
span as long as the minimum span of 20 Hz is not violated.
Frequency values for each range have to be defined relative to the center frequency.
The reference range has to be centered on the center frequency. The minimum span of
the reference range is given by the current TX Bandwidth.

Fast SEM ← Sweep List dialog box ← Sweep List ← Spectrum Emission Mask
Activates "Fast SEM" mode for all ranges in the sweep list. For details see "Fast Spec-
trum Emission Mask Measurements" on page 281.
