The Sony/Tektronix 338 and its sister model 318 are keyboard-controlled multifunction portable logic analyzers.

The 338 has 32 channels with 20 MHz maximum clock speed and 256 word memory, with a glitch capture function on the lower 8 channels. The standard probes are the P6451 (4 pieces) and P6107 (trigger/serial).

Model 338S1 adds an RS-232 interface, nonvolatile memory, and a serial state analysis function (5 to 9 bits/char, asynchronous or synchronous, two continuous word recognizers, 50 to 19.2K baud; binary, octal, decimal, hexadecimal, ASCII, or EBCDIC display).
