R116

The Tektronix R116 is a programmable pulse generator introduced in 1965 for use with automated measurement systems such as the 240 and R250. A modified version (R116 MOD703L) was part of the S-3130 testing system.

The R116 uses a 1N3716 tunnel diode to produce pulses.

Features	"Programmable" Double pulse mode

The R116 has a programming connector in the back. Eight operating parameters can be programmed digitally (by switch closure):

• Trigger Source
• Mode
• Period Range
• Delay or Burst Time Range
• Width Range
• Amplitude Range
• Polarity
• Rise Time/Fall Time Range

Seven more parameters are controlled by connecting external resistances:

• Period Multiplier
• Delay or Burst Time Multiplier
• Width Multiplier
• Amplitude Multiplier
• DC Offset
• Rise Time Multiplier
• Fall Time Multiplier
