INTRODUCTION AND SPECIFICATIONS
INTRODUCTION
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 timing 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 are menu-driven systems. This means that all operations are set up via menus that are displayed on the
monitor screen. There are three menus 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 (maximum) 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 memory for data. Glitches are captured on eight channels. Three
word recognizers can be specified on all channels and used in several different triggering sequences. The digital delay
counts up to 65,000 clock cycles. In the 318, data before or after the occurrence of a specified trigger sequence can be
acquired and stored at sample intervals ranging from 20 ns to 500 ms with two lock and trigger qualifiers. In the 338, data
before or after the occurrence of a specified trigger sequence can be acquired and stored at sample intervals ranging from
50 ns to 500 ms with four clock and trigger qualifiers. The stored data can be displayed on the CRT screen in a timing or
state format.
A composite video output for hard-copy units or video terminals is provided. This feature allows documentation 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 occurrence of a specified trigger sequence
can be acquired and stored at baud rates ranging from 50 to 19.2K baud. The stored data is displayed on the CRT screen
in binary, octal, decimal, hexadecimal, ASCII, or EBCDIC format.
The RS-232C interface port allows the 318S1/338S1 to be linked with terminal equipment through an asynchronous, full-
duplex modem. In remote control mode, the 318S1/338S1 can receive all control commands, memory control commands,
or reference memory data from the terminal equipment instead of the keyboard. It can send the CRT display information
or memory data to the terminal equipment via the RS-232C port.
