Sub Block Count

Defines the number of sub blocks. By default, the familiar SEM measurement with just

one single block of ranges is configured.

Remote command:

[SENSe:]ESPectrum<sb>:SCOunt on page 662

Sub Block / Center Freq

Defines the center frequency for an individual sub block. The center frequency deter-

mines the reference range used for each block.

For measurements with only one sub block, this setting corresponds to the global set-

ting in the "Frequency" settings (see Center Frequency).

Remote command:

[SENSe:]ESPectrum<sb>:SCENter on page 662

Standard

Defines the use of a standard settings file for a particular sub block. For details, see

"Standard Files" on page 183.

Remote command:

[SENSe:]ESPectrum<sb>:PRESet[:STANdard] on page 660

Edit Sweep List

Switches to the "Sweep List" tab of the "Spectrum Emission Mask" dialog box to con-

figure the individual frequency ranges and mask limits for the corresponding sub block.

See "Sweep List" on page 174.
