The Tektronix 2230 is a portable 100 MHz, dual-channel combination analog / digital storage scope, sister model of 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 is controlled by an Intel 8088 microprocessor. It features alphanumeric CRT readout of many of the front panel controls. It has a DB-9 auxiliary connector on the right side providing an external clock input as well as an output for an analog X-Y plotter 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, and a 26K battery backed memory board.
