4.16.5.1 Time-Interval Resolution Thresholds
The different time-interval resolutions are distinguished by two characteristics:
• Shortest and longest time-intervals available.
• Absolute resolution of the least-significant digit.
'Pulse Width' Time-Intervals
The following table shows the spans of output
Pulse Width time-intervals for the Logic-
Pulses Function, against their associated resolutions.
'Repetition' Time-Intervals
The following table shows the spans of output
Repetition time-intervals for the Logic-
Pulses Function, against their associated resolutions.
Absolute Span of Time-Intervals
Resolution
100ns 000.6 µs to 999.9 µs
100ns 00.0006 ms to 99.9999 ms
1µs 000.001 ms to 999.999 ms
10µs 0000.01 ms to 2000.00 ms
Pulse Width/Repetition Ratio Limits
The Pulse Width and Repetition time-intervals can be adjusted over their entire range of
values provided that the Pulse Width time-interval remains at least 0.3µs shorter than the
Repetition time-interval. An audible warning will be given if an attempt is made to set
a Pulse Width or Repetition time-interval which would produce a Pulse Width / Repetition
Interval ratio of 1 or greater. The user must reset either the Pulse Width or the Repetition
Interval to give a ratio less than 1. This rule applies whether OUTPUT is OFF or ON.
