The Tektronix 2212 is a portable mixed analog/digital storage oscilloscope with on-screen cursors. The 2216 is the 4-channel version.
The 2212 has two modes, analog and digital. In analog mode, the vertical signal path is all analog, from the BNC input connector to the electrostatic deflection plates of the CRT. In digital mode, the input signal is digitized and can be stored or printed or compared with live waveforms. Other signals such as the trigger level are controlled by the internal computer in both modes.
The 2212 is a dual-trace scope and is rated as having an analog bandwidth of 60 MHz. Bandwidth in digital mode is considerably lower (20 MHz).
There is a DB-25 connector on the rear panel for connecting a parallel-port printer. It prints correctly to an Epson-compatible printer and allows some customization of what is on the screen. The 2212 has a "roll" mode that emulates a strip chart recorder when in digital mode at slow sample rates.
