Section 4: Using the Model 9100: % Duty Function 4.11-5
Final Width = 215mm
4.11.4.2 % Duty Cycle Editing
Duty Cycle percentage values can be changed using 'Digit' and 'Direct' edit facilities. The
editing processes are not described in Section 3, but follow the same general rules as for
editing voltages.
The resolution of '%' values is set at four significant digits. There is only one absolute
level of resolution: 00.01%.
'% Duty' Value
The screen setting of the '% Duty' value is subject to the following limitations:
00.05% ≤ % Duty ≤ 99.95%
The actual setting is translated in software into a 'Mark' time-interval value, internally
calculated to be the required percentage of the set 'Period' time-interval value. Because
of the wide range of period values available, and the finite resolution of the 'Mark' time-
interval counter, it is possible only to determine a 'Mark' time-interval which is 'rounded'
to its nearest digit of resolution. The 9100 specification accommodates this rounding.
4.11.4.3 'Period' Time-Interval Editing
Period time-interval values can be changed using 'Digit' and 'Direct' edit facilities. The
editing processes are not described in Section 3, but follow the same general rules as for
editing voltages.
The resolution of duty cycle values is set at four significant digits, except that the
minimum value is 00.05%, and the maximum is 99.95%. Between these two values is one
span of constant resolution.
The resolution of time-interval values is set at six significant digits, except for the shortest
span of intervals at four significant digits. This leads to four repetition period interval
spans of constant resolution.
4.11.4.4 'Period' Time-Interval Ranges and Limits
The ranges of 'Period' time intervals are described in paras 4.11.5.2.
Analog hardware configurations for time-interval and voltage change are given in paras
4.11.5.3.
