E4438C Option SP2
Introduction
Introduction
The Dynamic Sequencing Option SP2 enhances the “segment advance” ARB capability to
allow jumping to any of the 256 different segments in ARB Waveform Memory. The next
segment to be played is determined dynamically via an 8-bit value input on pdata(7..0) and
is strobed in using the patt_trig_in2 signal.
NOTE
Symbol_sync_out signal is used only as a timing marker to define the setup
times for patt_trig_in2.
Linear Segment Switching
Linear Segment Switching is the term used to annotate the existing ARB-Waveform
Sequence feature. In this original mode of operation, Waveform Segments are listed
linearly within a Waveform Sequence Contents table on the Unit Interval (UI). The ARB
player then plays (advances) these segments in a LINEAR, incremental order, subject to a
set of qualifying Segment Advance triggers.
Dynamic Segment Switching
Dynamic Segment Switching will allow the arbitrary or dynamic selection of the next
segment to be played. Segment ordering is achieved by applying and strobing a next
segment index number to the Aux IO port on the rear of the instrument, using the rising
edge of Pattern Trigger Input-2. The next segment will then play once the current segment
has finished playing, subject to a further qualifying condition.
