8.20 :SEQuence Subsystem
Sequences are made of a number of arbitrary waveforms, which can be linked and
looped in user-programmable order. Sequences are generated from waveforms
stored in the waveform memory as memory segments.
Steps to generate a sequence:
 Generate the waveform segments using the Arbitrary Waveform Commands
(TRACe Subsystem).
 Define a sequence (:SEQ[1|2]:DEF:NEW).
 Fill the sequence with segments (:SEQ[1|2]:DATA).
 Select sequence mode (:SOUR:FUNC[1|2]:MODE STSequence).
 Select a sequence (:STAB[1|2]:SEQ:SEL).
 Start signal generation with :INIT:IMM.
This subsystem does not support the following functionality offered by the STABle
subsystem.

 Idle delay commands
8.20.1 [:SOURce]:SEQuence[1|2]:DEFine:NEW <length>
Command
:SEQ:DEF:NEW
Long
:SEQuence:DEFine:NEW
Parameters
<length>
Parameter Suffix
None
Description
<length> number of sequence table entries.
This command defines a new sequence. The <length> parameter specifies the
number of sequence table entries in the sequence.
The new <sequence-id> in the range 0…512K–2 is returned. This value is the index of
the first sequence table entry of this sequence.
