Programming the Instrument Trigger Modes
Burst
Set Burst mode by setting the
:TRIGger:COUNt
to the burst count
required. The trigger source sets the pulse period for the pulses within
the burst (See table in Pulses on page 39).
:TRIGger:COUNt 16 Burst of 16 pulse periods
:TRIGger:SOURce INTernal1 Pulse period from internal PLL.
:DIGital:PATTern OFF Disable pattern data
Pattern
Set Pattern mode by setting the
:DIGital[STIMulus]:PATTern:SEGMent[1|2|3|4]:LENGth
to the
required pattern length, and switching on digital pattern data. The trigger
source sets the pulse period for the data pulses (See table in Pulses on
page 39):
#Pattern length 512
:DIGital[:STIMulus]:PATTern:SEGMent1:LENGth 512
:DIGital[:STIMulus]:PATTern:SEGMent2:LENGth 0
:DIGital[:STIMulus]:PATTern:SEGMent3:LENGth 0
:DIGital[:STIMulus]:PATTern:SEGMent4:LENGth 0
#Disable counted segment loop
:DIGital[:STIMulus]:PATTern:LOOP:COUNt 1
#Jump back to start of segment 1 after the last bit of the last
segment (here: segment 1)
:DIGital[:STIMulus]:PATTern:LOOP:INFinite[:STATe] ON
:DIGital[:STIMulus]:PATTern:LOOP:INFinite:STARt SEGM1
:TRIGger:SOURce INTernal1 Pulse period from internal PLL
:DIGital:PATTern ON Enable pattern data
:DIGital:SIGNal1:FORMat NRZ Set OUTPUT 1 data to NRZ
:ARM:MODE STARted
:ARM:SOURce EXT1 Switch to started by EXT1
