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
.” If delay and width are
not programmed, default values of 1.5ms (delay) and 500ns (width) will be used and queries will return 0.
