The '''Tektronix 2236''' is a 100 MHz portable scope with a dual time base and a built-in DMM/counter. | The '''Tektronix 2236''' is a 100 MHz portable scope with a dual time base | ||
and a built-in DMM/counter with a dedicated 9-digit VF display. | |||
Apart from the counter, it is the same as the [[2235]]. | |||
In addition to signal frequency and period, the counter can measure delay time and delta time from the delayed timebase. | |||
