Segment ARB waveforms
Segment ARB
®
waveforms are configured and controlled from the PG2 tabs in the GUI. Figure 5-
4 explains how to use the GUI for standard pulse output.
NOTE Due to the Segment ARB engine overhead, there is an additional 10 ns interval
added to the end of the last segment of a Segment ARB waveform. During this
interval, the output voltage, solid-state relay control (high endurance output relay
(HEOR)), and trigger output values remain the same as the final value reached in the
last segment.
Start, stop, and time restrictions:
• The start level of the first segment and the stop level of the last segment must be the same.
In Figure 5-4 , Segment 1 start and Segment 7 stop are both set for 0.0 V.
• The stop level for a segment must be the same as the start level for the next segment. In
Figure 5-4 , the stop level for Segment 1 is 1.0 V, which is the same as start level for
Segment 2 (no discontinuities are allowed).
• Time values are in 10 ns increments, with a minimum of 20 ns.
Segment ARB pulse waveform previewers : KPulse provides a preview of configured Segment
ARB
®
waveforms for each enabled channel. Each waveform previewer shows the segment levels
and timing for the waveform.
