TEST SETUP DESCRIPTION
Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1045.
The input waveform is produced by a precision pulse generator under software control. Time delays are
measured by a time interval counter (20 ps resolution) connected to the output. The DS1045 parallel
inputs are controlled by an interface to a central computer. All measurements are fully automated with
each instrument controlled by the computer over an IEEE 488 bus.
