• Notes
• The Tektronix Type 184 Time Mark Generator provides high accuracy time signals for calibration purposes, e.g. for checking and adjusting of oscilloscopes.
  It is crystal controlled and provides 16 marker intervals, 5 sine wave frequencies, and 7 trigger-pulse intervals. The Type 184 is transistorized (plus 6 nuvistors) and is frequency controlled by a temperature-stabilized 10-MHz crystal oscillator.
  Marker Output:
  Positive-going markers with 16 intervals of 100 ns to 5 s in 1-5-10 sequence, 1-V minimum peak amplitude into 50 Ω
  Marker Amplifier Output:
  Positive- or negative-going markers with 14 intervals of 1 µs to 5 s in 1-5-10 sequence, 25-V minimum amplitude into 1 kΩ.
  Sinewave Outputs:
  10-ns, 20-ns and 50-ns sinewave signals at marker output connector with 1-V minimum peak to peak amplitude into 50 Ω. 2-ns and 5-ns sinewave signals at HF output connector with 0.3 V minimum peak to peak amplitude into 50 Ω.
  Trigger Output:
  Positive-going pulses with 7 intervals of 1 µs to 1 s in 1-10 sequence, 0.4-V minimum amplitude into 50 Ω, 2.5-V minimum amplitude into open circuit.
