Command
:CALCulate:DDEMod:SEGMent1|…|6:LIMit:DEViation:OFFSet <real>
:CALCulate:DDEMod:SEGMent1|…|6:LIMit:DEViation:OFFSet?
Example
:CALC:DDEM:SEGM1:LIM:DEV:OFFS 10.0
Set the deviation accuracy limit of segment1 to 10 %
:CALC:DDEM:SEGM1:LIM:DEV:OFFS?
Query the deviation accuracy limit of segment1
Couplings Available only when the modulation format is FSK formats or CPM (FM)
If FSK Deviation Reference is Auto, this control is grayed-out. Pressing this control in this case
generates a message “It’s not available while FSK Reference Deviation is Auto”

Select Limit
Specifies the selected limit. The term “selected limit” is used throughout this
document to specify which trace limit will be affected by the functions.
Notes The selected limit is remembered even when not in the Limit Menu
Preset Limit 1, not affected by Mode Preset, preset by Restore Mode Defaults
State Saved Saved in instrument state
Limit On/Off
Selects whether the limit is turned on or off. While trying to turn on the trace limit, it
will check whether the limit’s x/y axis unit and the selected window’s x/y axis unit
match. If matched, the limit line will be turned on. If not, the limit will be turned off
and a settings conflict message “The unit of the limit and the selected window
doesn’t match.” will be displayed.
The limit will be turned off if the data of the selected window is changed and its x/y
units do not match those of the current limit.
