Digital Standard W-CDMA (NTT DoCoMo/ARIB 0.0) SMIQ
1125.5555.03 E-92.158
(MODULATION...) FILTER MODE
Selection of filter mode.
LOW_ACP Filter for minimum Adjacent C
hannel
Power.
IEC/IEEE-bus command
:SOUR:WCDM:FILT:MODE LACP
LOW_EVM Filter for minimum vector error.
IEC/IEEE-bus command
:SOUR:WCDM:FILT:MODE LEVM
LOW DISTORTION
MODE
Switch on/off of low-distortion mode.
After switch-on, the level of the IQ baseband signals
is reduced by 3 dB. In some cases, this might reduce
undesired intermodulation products. OFF is normally
the more favourable setting.
IEC/IEEE-bus :SOUR:WCDM:LDIS:STAT OFF
TRIGGER MODE
Opens a window for selecting the W-CDMA sequence.
AUTO The calculated W-CDMA chip sequence is cyclically
repeated.
IEC/IEEE-bus command :SOUR:WCDM:SEQ AUTO
RETRIG The W-CDMA chip sequence is continuously re-
peated. A trigger event causes a restart from frame 1.
IEC/IEEE-bus command :SOUR:WCDM:SEQ RETR
ARMED_AUTO The W-CDMA chip sequence cannot be started from
frame 1 until a trigger event has occurred. The unit
then automatically switches over to the AUTO mode
and can no longer be triggered.
IEC/IEEE-bus command :SOUR:WCDM:SEQ AAUT
ARMED_RETRIG The W-CDMA chip sequence cannot be started from
frame 1 until a trigger event has occurred. each new
trigger event causes a restart.
IEC/IEEE-bus command :SOUR:WCDM:SEQ ARET
EXECUTE TRIGGER
Executes a trigger event to start the W-CDMA chip sequence.
IEC/IEEE-bus command :TRIG:DM:IMM
TRIGGER...
Opens a window for selecting the trigger source, for configuring the trigger
output signals and for setting the time delay of an external trigger signal.
