TEST SETUP DESCRIPTION
Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1135L.
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 DS1135L output taps
are selected and connected to the interval counter by a VHF switch control unit. All measurements are
fully automated with each instrument controlled by the computer over an IEEE 488 bus.
