For channels with AT45 output option, the maximum For channels with AT45 output option, the maximum frequency is limited to 100 kHz. The pulse width can be set frequency is limited to 100 kHz. The pulse width can be set over the standard range of the unit with active high outputs over the standard range of the unit with active high outputs when set to high impedance mode. In low impedance mode, when set to high impedance mode. In low impedance mode, the pulse width is limited to a maximum of 10 seconds and the pulse width is limited to a maximum of 10 seconds and the active high output is no longer allowed. the active high output is no longer allowed. To maintain the fastest rise times, care must be taken with To maintain the fastest rise times, care must be taken with cabling and termination. Low capacitance cable and 50 ohm cabling and termination. Low capacitance cable and 50 ohm termination will provide the fastest rise times while termination will provide the fastest rise times while minimizing overshoot. minimizing overshoot.
