This manual will help you service both the Sony/Tektronix 318 Logic Analyzer and the Sony/Tektronix 338 Logic Analyzer.
The procedures and descriptions contained herein apply to both Instruments. Unless otherwise specified, all screen
displays have been developed from the 338S1. The 338S1 contains all the basic features of the standard 338 plus the
following additional features: serial state analysis, an RS-232C interface, and non-volatile memory.
DESCRIPTION
The Sony/Tektronix 318 and 338 are keyboard-controlled, multifunction, portable logic analyzers.
Each can operate as a parallel tim ing analyzer or a parallel state analyzer, and each is provided with composite video
output. The Sony/Tektronix 318S1 and 338S1 provide several additional features: serial state analysis, RS-232C
interface, and non-volatile memory.
The instruments ar e m enu-driven s ystems. T his m eans that all operations ar e set up via m enus that are displayed on the
monitor screen. There are three m enus for setting up parallel data acquisition, three menus for setting up serial data
acquisition, one menu for remote operation, one menu for non-volatile memory operation, and two menus for data display.
MODES OF OPERATION
When used as a parallel timing analyzer, the 318 provides a 16-channel-wide input, 50 MHz (maxim um ) clock speed, and
256 bits/channel memory for data. Glitches are captured on all 16 channels. The 338 provides a 32-channel-wide input,
20 MHz (maximum) clock speed, and 256 bits/channel m emor y for data. Glitches are captur ed on eight channels. T hree
word recognizers can be specified on all c hannels and used in several different triggering s equences. The digital delay
counts up to 65,000 clock cycles. In the 318, data before or after the occurrence of a spec ified trigger s equence can be
acquired and stored at sample intervals ranging from 20 ns to 500 ms with two lock and trigger qualif iers. In the 338, data
before or after the occurrence of a spec if ied tr igger s equenc e c an be acquir ed and s tored at s ample intervals ranging from
50 ns to 500 ms with four clock and trigger qualif iers. The s tored data can be displayed on the CRT sc reen in a timing or
state format.
A composite video output for har d-copy units or video terminals is provided. This feature allows doc umentation of test
results and operating parameters.
As a serial state analyzer, the 318S1/338S1 acquires serial data in five, six, seven, eight, or nine bits/character in
asynchronous or synchronous timing. Two continuous word recognizers provide triggering upon recognition of preset
words. The digital delay counts up to 65,000 words. Data before or after the occ urrence of a specif ied trigger sequence
can be acquired and stored at baud rates ranging from 50 to 19.2K baud. T he s tored data is dis played on the CRT scr een
in binary, octal, decimal, hexadecimal, ASCII, or EBCDIC format.
The RS-232C interface port allows the 318S1/338S1 to be link ed with terminal equipment through an asynchronous, fullduplex modem. In remote control mode, the 318S1/338S1 c an r eceive all c ontr ol commands, m emory control commands,
or reference mem ory data from the ter minal equipm ent instead of the keyboard. It can send the CRT display inform ation
or memory data to the terminal equipment via the RS-232C port.

Introduction & Specifications-318/338 Service
The non-volatile mem ory can retain three setups and one set of reference or ac quired data for about five years. Each
memory area is selectable f or the use of parallel or serial inform ation. The current setup of the instrum ent is stored by
keyboard control or control comm ands from the term inal. The stored setup inform ation is recalled in the same manner.
The data can be stored and recalled only by the 318S1/338S1 keyboard.
All functional parameters and operation of the instrument ar e programmable from the front panel or over the RS-232C
port.
