Operating Instructions-318/338 Service
ERROR MESSAGE AND ACQUISITION STATUS READOUT
The 318/338 has a comprehensive set of error and acquisition status messages. These messages appear on the bottom
line of the screen: the error message is at the left of the screen and is displayed in blinking, highlighted video; acquisition
status is at the right hand of the screen and is displayed in blinking video.
MAJOR MODE SELECTION FIELD
The major mode (PRL/SER/KBD/RMT/NVM) selection field appears in the top left corner of the screen (except when
displaying the RS-232 Setup menu or the Non-Volatile Memory Setup menu). After making any changes in this field, you
must press the EXECUTE key to access the selected mode.
INPUTS DURING ACQUISITION
Even when acquiring data (when waiting for a trigger or in REPEAT mode), the 318/338 can accept any keys in any fields
except for those that generate the message: PRESS STOP. This capability allows you to change the delay value or
sample clock while looking at continuously acquired data, without pressing the STOP key.
MENU FUNCTIONS
SETUP MENU
The Setup menu (parallel) serves two functions. First, it is used to specify the acquisition mode (SINGLE, REPEAT, RPT
UNTIL ACQ = REF, RPT UNTIL ACQ
≠
REF) that will be used during acquisition.
The second function of the Setup menu is to determine the way in which acquisition channels are organized for display. It
organizes the channels into logical groups. This information is then used by the Trigger menu for organizing the word
recognizer channels, and by the State Table menu for organizing the data display. This channel organization is
independent of the order in which channels are connected to the system under test. The organization only affects the
display, not the actual acquisition. Changes can be made to the data display after the data has been acquired.
The Setup menu (serial) also serves the following functions: communication mode (ASYNC/SYNC) selection, baud rate
selection, input polarity selection, bits/word selection, and parity selection.
THRESHOLD MENU
The function of the Threshold menu is to determine probe input thresholds (including data lines and the external clock
line).
