It has both an analog mode and a digital mode. In the digital storage mode, up to three waveform sets (CH 1 and/or CH 2) may be stored in a save ref. memory and recalled for display at a later time.
The 2230 features alphanumeric CRT readout of many of the front panel controls. A DB-9 auxiliary connector on the right side provides an external clock input as well as an analog X-Y plotter output to make permanent copies of the display. This feature can be accessed through the "Mem select" menu.
Some firmware versions have a diagnostics menu with the Tektronix logo and wizard image.
The Cursor knob is prone to failure. It becomes jittery and will not scroll properly.
Recommended cart is the K212.

The 2230 is controlled by an Intel 8088 microprocessor with firmware in a pair of 27512 EPROMs, and six TMS4426 16K×4 DRAMs. The A/D converter is a Sony CX20052A (8 bit, 20 MHz, ECL output). A pair of MCM2016H 2K×8, 70 ns RAMs serve as acquisition memory.
