The Tektronix Type 106 is a square-wave generator introduced in 1966. It has four outputs:
- Fast Rise +Output: 500 mV into 50 Ω load, positive-going pulse, 1 ns rise time, 50 Ω output impedance, GR-874 connector
- Fast Rise −Output: 500 mV into 50 Ω load, negative-going pulse, 1 ns rise time, 50 Ω output impedance, GR-874 connector
- High Amplitude Output: 12 V into 50 Ω load, 12 ns rise time, 600 Ω output impedance, GR-874 connector
- Trigger Output: 100 mV into 50 Ω load, 50 ns rise time, 150 Ω output impedance, BNC connector
The 1 ns rise-time outputs are generated using diodes to clip a high amplitude signal. In units with serial numbers less than 1190, GaAs diodes were used for clipping. After serial number 1190, silicon diodes were used.
