The Tektronix Type 106 is a squarewave generator introduced in 1966. It has four outputs:
- Fast Rise +Output: 500mV into 50 ohm load, positive-going pulse, 1ns risetime, 50-ohm output impedance, GR connector
- Fast Rise -Output: 500mV into 50 ohm load, negative-going pulse, 1ns risetime, 50-ohm output impedance, GR connector
- High Amplitude Output: 12V into 50 ohm load, 12ns-risetime, 600-ohm output impedance, GR connector
- Trigger Output: 100mV into 50 ohm load, 50ns risetime, 150 ohm output impedance, BNC connector
The 1ns-risetime 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.
