+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]].
+An "A" model also exists.
+In addition to signal frequency and period, the counter can measure delay time and delta time from the delayed timebase.
