Insert before Range / Insert after Range
Inserts a new range to the left (before) or to the right (after) of the range in which the
cursor is currently displayed. The range numbers of the currently focused range and all
higher ranges are increased accordingly. The maximum number of ranges is 30.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:INSert on page 668
Delete Range
Deletes the currently focused range, if possible. (The reference range cannot be
deleted. A minimum of three ranges is required.) The range numbers are updated
accordingly.
Remote command:
[SENSe:]ESPectrum<sb>:RANGe<ri>:DELete on page 665
Symmetrical Setup
Any changes to the range settings in active "Symmetrical Setup" mode lead to sym-
metrical changes in the other ranges (where possible). In particular, this means:
●
Inserting ranges: a symmetrical range is inserted on the other side of the reference
range
●
Deleting ranges: the symmetrical range on the other side of the reference range is
also deleted
●
Editing range settings: the settings in the symmetrical range are adapted accord-
ingly
Note: If "Fast SEM" mode is deactivated while "Symmetrical Setup" mode is on, "Sym
Setup" mode is automatically also deactivated.
If "Fast SEM" mode is activated while "Symmetrical Setup" mode is on, not all range
settings can be set automatically.
Remote command:
[SENSe:]ESPectrum<sb>:SSETup on page 676
Multi-SEM (Sub Block) Settings
Access: "Overview" > "Select Measurement" > "Spectrum Emission Mask" > "Sub
Blocks"
In the Spectrum application application only, spectrum emissions can be measured for
multiple sub blocks of channels (see "SEM with Multiple Sub Blocks ("Multi-SEM")"
on page 169). Sub blocks are a set of multiple ranges around a defined center fre-
quency (carrier).
By default, a single sub block is assumed. If more than one sub blocks are defined,
additional tabs are inserted for each sub block in the individual tabs of the "Spectrum
Emission Mask" configuration dialog box.
