SW2. The figure “Setting the pulse period or signal width on SW1 or SW2” on
page 3-27 shows a single pulse and a rectangular wave.
• Single pulse (in seconds) – If SW1 or SW2 is programmed to generate a
pulse as a timed or threshold event, then this field specifies the period of
the signal (single pulse width; range 0.1 to 60 seconds).
• Rectangular wave (in seconds) – If SW1 or SW2 is programmed to
initiate a rectangular wave as a timed or threshold event, then this field
specifies the period of the signal (the width of one pulse period in a
rectangular wave or pulse train; range 0.2 to 60 seconds).
