Operating Instructions-318/338 Service
TRIGGER MENU
The Trigger menu sets up the major acquisition parameters. First, it specifies which trigger mode (INT, EXT, or INT OR
EXT) will be used during acquisition. Then it specifies the acquisition clock (external or internal) and trigger position
(BEGIN, CENTER, END, or DELAY), and enables clock or trigger qualifier lines. The Trigger menu also controls all word
recognition, triggering parameters, and glitch triggering. The Trigger menu (serial) also controls SYNC WORD and HUNT
WORD in synchronous mode.
STATE TABLE MENU
The State Table menu has two submenus: SRCH (search) and CMPR (compare). The SRCH (search) function is used
for searching through ACQ (acquisition) or REF (reference) memory for a specific data word or a word including a glitch. It
will show the number of occurrences of the specific data in the memory and it will also show the relative position of the
memory cursor to these data. The CMPR (compare) function is used in conjunction with REF (reference) memory. REF
memory is filled with a copy of ACQ memory when EXECUTE is pressed (edit cursor in the ACQ-REF field).
The CMPR displays then show differences between REF memory contents and any later ACQ memory contents within the
CMPR WDO (window). The channel organization of the parallel state display is controlled by the Setup menu.
TIMING DIAGRAM MENU (PARALLEL ONLY)
The Timing Diagram menu (parallel) has two submenus: SRCH (search) and
∆
T (delta time). The search function is the
same as in the parallel State Table menu for displayed data or data on that page. The
∆
T (delta time) function makes a
timing measurement between two given locations (
∆
T and C) in the waveform display.
CHARACTER MENU (SERIAL ONLY) (318S1/338S1)
The Character menu (serial) has two submenus: SRCH (search) and CMPR (compare). These are the same as
described for the State Table menu. This display shows 256 bytes of data on one screen in either ASCII or EBCDIC
format.
REMOTE (RMT) MENU (318S1/338S1)
The purpose of external communication is to allow the user to store reference memories; to retrieve acquisition, reference,
and glitch memories; to store and retrieve setups outside the 318/338; and to be able to control the 318/338 from an
external controller. You can select BAUD RATE and ECHO in the RMT mode.
NON-VOLATILE (NVM) MENU (318S1/338S1)
The values of setup parameters and acquisition or reference memory can be stored in NVM memory. This means that
once the parameters and memory are saved, they will not change (in the NVM) when the 318/338 is powered off and back
on again.
NOTE
When the NVM diagnostics test is run, all information stored in the NVM memory is
erased.
