Activating Fast SEM mode
"Fast SEM" mode is activated in the sweep list (see
Chapter 7.6.5.1, " Sweep List "
on page 221) or using a remote command. Activating the mode for one range auto-
matically activates it for all ranges in the sweep list.
Remote command
:
Fast SEM not supported for multiple sub blocks
For SEM with multiple sub blocks, fast SEM is not available. If more than one sub
block is defined and a standard is loaded which contains an active fast SEM setting,
this setting is disabled.
For more information on multi-SEM measurements, see
Multiple Sub Blocks ("Multi-SEM")"
Consequences
When the "Fast SEM" mode is activated, the ranges for which these criteria apply are
displayed as one single range. The sweep time is defined as the sum of the individual
sweep times, initially, but can be changed.
If "Symmetrical Setup" mode is active when "Fast SEM" mode is activated, not all
sweep list settings can be configured symmetrically automatically (see also
Any other changes to the sweep settings of the combined range are applied to each
included range and remain changed even after deactivating "Fast SEM" mode.
