The Tektronix 2230 is a portable 100 MHz, dual-channel combination analog / digital storage scope, introduced in 1986. It was superseded by the 2232 in 1990. Sister models include the 2220 and 2221.

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.

Options include RS-232 and GPIB interface boards, which include a 32K (26K available) battery backed memory daughter board (the same options for the 2220 and 2221 do not include the memory).

Recommended cart is the K212.
