Parameter Measurement Information

  • Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tt < 6 ns.
  • The outputs are measured one at a time, with one input transition per measurement.
