Leading Edge and Trailing Edge Transition Time
The leading-edge and trailing-edge transition times have five setting ranges as
shown in Table 7-16.
Table 7-16 Ranges and Resolutions of Leading and Trailing Transition Time
where,
• leading-edge transition time < pulse width × 0.8
• trailing-edge transition time < (pulse period − pulse width) × 0.8
• Leading and trailing-edge transition times for a PGU must be in the range
specified by a Range.
Trigger Output
PGUs output trigger signal to synchronize with external pulse generators. If an
41501A/B has PGUs, you can see a trigger output terminal on its rear panel. For
details of trigger functions, see Chapter 8.
