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 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 [[ROM images|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]].

==Internals==
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 [[156-2248-00|Sony CX20052A]] (8 bit, 20 MHz, ECL output).  A pair of MCM2016H 2K×8, 70 ns RAMs serve as acquisition memory.
