2236

Manuals – Specifications – Links – Pictures

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.
