... CMOS silicon design and industry standard packaging. The DS1040 series of pulse generators provide a nominal width accuracy ns, whichever is greater. In response to the rising edge of the input (trigger) pulse, the DS1040 produces an output pulse with a width determined by the logic states of the three parallel programming pins. For convenience, both inverting and non-inverting outputs are supplied ...

... TEST SETUP DESCRIPTION Figure 4 illustrates the hardware configuration used for measuring the timing parameters on the DS1040. The input waveform is produced by a precision pulse generator under software control. The intrinsic delay is measured by a time interval counter (20 ps resolution) connected between the input and each output ...
