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. Outputs are selected and connected to the counter by a VHF switch control unit. Width
measurements are made by directing both the start and stop functions of the counter to the same output.
All measurements are fully automated, with each instrument controlled by a central computer over an
IEEE 488 bus.
