The Tektronix 213 is a miniature portable oscilloscope introduced in 1975. It combines a 3½-digit DMM and a 1 MHz single channel scope in one unit. The maximum sweep rate is 0.4 μs/div with ×10 sweep magnifier.

The 213 provides true RMS voltage and current measurements. It is battery or AC line powered.
