TEST SETUP DESCRIPTION
Figure 4 illustrates the hardware configuration used for measuring the timing parameters of the DS1020.
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 DS1020 serial and
parallel ports are controlled by interfaces to a central computer. All measurements are fully automated
with each instrument controlled by the computer over an IEEE 488 bus.
