SMIQ Digital Standard DECT
1125.5555.03 2.323 E-9
(MODULATION...) SET TO
STANDARD
Sets the subsequent modulation parameters to the
values predefined by the standard.
IEC/IEEE-bus :
SOUR:DECT:STAN
MODULATION TYPE
Selection of the modulation type. GFSK is preset.
IEC/IEEE-bus :
SOUR:DECT:FORM GFSK
FSK DEVIATION
Input value for the frequency deviation for GFSK
modulation
IEC/IEEE-bus :
SOUR:DECT:FSK 280 KHZ
SYMBOL RATE
Input value for the symbol rate. 1152 ksymbols/s are
preset.
IEC/IEEE-bus :
SOUR:DECT:SRAT 1151 KHZ
FILTER TYPE
Selection of baseband filter. For π/4 DQPSK modul-
ation, a selection between Nyquist filters COS and
SQRCOS or a user-defined filter USER (cf. Section
Digital Modulation) is possible.
IEC/IEEE-bus
:SOUR:DECT:FILT:TYPE COS
FILTER PARAMETER
Input value for the BT value for Gauss filtering or for
the roll-off factor for Nyquist filtering.
IEC/IEEE-bus
SOUR:DECT:FILT:PAR 0.51
TRIGGER MODE...
Opens a window for selecting the trigger mode.
AUTO The DECT signals are continuously transmitted in the
activated slots.
IEC/IEEE-bus command
SOUR:DECT:SEQ AUTO
RETRIG The DECT signals are continuously transmitted in the
activated slots. A trigger event causes a restart. This
mode is not available if values different from zero are
set for TIMING ADJUSTMENT or JITTER
SIMULATION.
IEC/IEEE-bus command :
SOUR:DECT:SEQ RETR
ARMED_AUTO DECT signal generation does not start 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:DECT:SEQ AAUT
ARMED_RETRIG DECT signal generation does not start until a trigger
event has occurred. The unit then automatically
switches over to the RETRIG mode. Each new trigger
event causes a restart. This mode is not available if
values different from zero are set for TIMING
ADJUSTMENT or JITTER SIMULATION.
IEC/IEEE-bus command :
SOUR:DECT:SEQ ARET
