Setting up a Sequence in SCPI

Setting up a Sequence in SCPI requires only two steps:

Create the sequence:

:SOUR:PATT:SEQ:DATA (Version= 1.0; Start= IMM;

Block 1= C:\<Instrument Model>\Pattern\MyHeader.ptrn;

Block 2= PRBS23, 512, TrigOn;

Block 3= C:\<Instrument Model>\Pattern\MyFooter.ptrn;

Loop= B3, B3, 20;

Loop= B2, B2, AuxInRising)

Enable sequence execution:

:SOUR1:PATT:SEL SEQ

If you wish to change the Trigger Out port from Divided Clock to Sequence

Trigger, use the command:

:SOUR3:TRIG SEQ

By default, each block is set to TrigOn, and a trigger will be output whenever block

execution starts.
