Notes:
1. Not affected by *RST or :SYSTem:PRESet.
2. 1 on power-up; otherwise not affected by *RST or :SYSTem:PRESet.
3. Minimum and default pulse delay and width values depend on pulse duty cycle. See
Section 5 , “ Duty cycle .” If delay and width are
not programmed, default values of 1.5ms (delay) and 500ns (width) will be used and queries will return 0.
