The sawtooth, triangle and sine outputs have to work independent of the
pulsewidth setting. If the pulsewidth affects the triangle or the sine
output has no output the module is defective. Before you send it back for
repair to your dealer please check if the internal connection between the
two boards is OK (i.e. if the 10 pin ribbon connector is firmly plugged on
the pin header of the small output board).
