Manuals

The 318 has 16 channels with 50 MHz maximum clock speed and 256-word memory, with a glitch capture function on all channels. The standard probes are the P6451 (2 pieces) and P6107 (trigger/serial).

Model 318S1 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).
