2230

Manuals – Specifications – Links – Pictures

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. 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.

An optional 26K battery backed memory board was available as an option.
