Programming a Sequence
Set up the test set attenuation
Set up 20dB of mechanical attenuation; this is fixed for whole Sequence:
:SENSe:LSEQuencer:POWer:RF:ATTenuation 20
Set up the RF input and output ports
In this example use the RF I/O 1 port as both input and output:
:SENSe:FEED:RF:PORT[:INPut] RFIO1
:SENSe:FEED:RF:PORT:OUTPut RFIO1
Set up the List Sequencer measurement parameters
Set trigger timeout:
:SENSe:LSEQuencer:TIMeout:TRIGger 2 s
Set include source in sequence; for this example the source is not included in the sequence:
:SENSe:LSEQuencer:INCLude:SOURce 0
Set Abort on Limit Fail to ON:
:SENSe:LSEQuencer:ABORt:LIMit:FAIL:STATe ON
Set the Abort on Error parameter to ON:
:SENSe:LSEQuencer:ABORt:ERRor:STATe ON
Set up the input trigger
The input trigger is set for each acquisition (below), but set the trigger polarity for the duration of a
sequence as follows (in the case of the EXTernal1 and External2 triggers, set the level as well):
:TRIGger:LSEQuencer:VIDeo:SLOPe POSitive
:TRIGger:LSEQuencer:EXTernal1:SLOPe POSitive|NEGative:
:TRIGger:LSEQuencer:EXTernal1:LEVel <level>
:TRIGger:LSEQuencer:EXTernal2:SLOPe POSitive|NEGative:
:TRIGger:LSEQuencer:EXTernal2:LEVel <level>
