The Tektronix S-54 is a pulse generator head designed for use with the 7S12 as a long line TDR unit. It has a 1 ns risetime and variable pretrigger pulse output.

The pretrigger-to-main pulse jitter is specified to be 100 ps or less when the lead time is set to 120 ns. The output pulse is generated by a Schottky diode clamping circuit.

Specifications

  • Main Output:
    • Output amplitude: +400 mV into 50 Ω (BNC)
    • Rise time: < 1 ns
    • Pulse duration: 25 µs ± 2 µs.
  • Pre-trigger output:
    • Amplitude: +200 mV into 50 Ω (BSM)
    • Rise time: 5 ns
    • Pre-trig time: 120 ns – 1 µs before main pulse
    • Jitter: < 100 ps at 120 ns, < 1 ns at 1 µs
    • Pulse duration: 20 ns
