To change the start/stop frequency of the first or last range, respectively, select the
appropriate span in the [SPAN] configuration dialog. You can set a span that is smaller
than the overall span of the ranges. In this case, 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.
Define frequency values for each range relative to the center frequency. Center the ref-
erence range on the center frequency. The current "Tx Bandwidth" defines the mini-
mum span of the reference range (see
Remote command:
[SENSe:]LIST:RANGe<ri>[:FREQuency]:STARt
[SENSe:]LIST:RANGe<ri>[:FREQuency]:STOP
Fast SEM
Activates "Fast SEM" mode for all ranges in the sweep list. For details, see
ter 7.6.4.3, "Fast SEM Measurements"
Note:
If you deactivate "Fast SEM" mode while "Symmetrical Setup" mode is on,
"Symmetrical Setup" mode is automatically also deactivated.
If you activate "Fast SEM" mode while "Symmetrical Setup" mode is on, not all range
