TEST SETUP DESCRIPTION

Figure 3 illustrates the hardware configuration used for measuring the timing parameters on the DS1005.

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 between the input and each tap. Each

tap is selected and connected to the counter by a VHF switch control unit. All measurements are fully

automated, with each instrument controlled by a central computer over an IEEE 488 bus.
