The pulse width can be set over the standard range of the unit with active high outputs when set to high impedance mode. In low impedance mode, the pulse width is limited to a maximum of 10 seconds and the active high output is no longer allowed. To maintain the fastest rise times, care must be taken with cabling and termination. Low capacitance cable and 50 ohm termination will provide the fastest rise times while minimizing overshoot.
