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.
