The sampling gate time should be less than a one-half cycle at the highest RF frequency.
The aperture jitter of the ADC sampling [[phi].sub.Rx] (Equation 6) is only 60 ps, so the sampling gate moves in space by less than 1 cm (one part in 10,000), thus ensuring that the correlation of the two copolar returns can be measured to high accuracy.
The reference clock measurement approach used in the Tektronix 82A04 Module avoids most of this problem by simultaneously strobing the data and reference sampling gates. Nevertheless, even in this technique, the small mismatch between the sampling gates themselves contributes similar types of errors albeit at much higher frequency.
