The Tektronix 1230 is a logic analyzer chassis that supports 16 to 64 channels at 100 MHz asynchronous or 25 MHz synchronous capture rate. It was introduced in 1989, a year after the very similar 1225 and 1220, the difference being board layout and the number of channels. The 1230B variant added an internal rechargeable battery pack for portable operation.

The number of channels depends on the number of acquisition cards installed. The mainframe will accept 2 to 4 cards that included the 1230E1 16-channel card (16×25 MHz state channels, 8×50 MHz or 4×100 MHz timing channels), and the 1230DSM digitizing scope card (2×100 MS/s). A bundle of a 1230 with a 1230DSM was sold as the 1230D instrument.

Four user-installable option boards were available − parallel printer interface, RS-232 interface, GPIB interface and on-line notes in foreign languages. Tektronix also had a software package for DOS PCs (S43R101) to control the analyzer via the RS-232 port.

An optional rack mount adapter was also available, 016-0947-00.

See the Microprocessor support table for microprocessor disassembly configuration options.
