Many Tektronix oscilloscopes and timebases have a multi-turn potentiometer on the front panel allowing the operator to precisely select the delay time of a second sweep. Terms related to this are:
- delay time multiplier, aka DTM or D.T.M. (The function that the control performs.)
- Helidial ?
- Helipot (A division of Beckman Instruments that made precision multi-turn pots.)
- Duodial (A mechanical indicator for the position of the multi-turn pot.)
