IEEE-488 PROGRAMMING
HP-85 Programming Example-Use the program below to
run the self test and obtain and display the Ul status word.
In this program, the instrument is placed in remote (line
10) and then programmed to perform the self test (line 20).
The program waits 10 seconds for the instrument to per-
form the self test (line 30), and then obtains and displays
the err"r status word (lines 40.70). B6 is the byte that flags
the result of the self test; this bit will be set to 1 if a failure
occurs.
Model 8573 Programming Example-Add the following
lines to the modified declaration file (paragraph 4.6.3) to
run the self test and display the resulting err"r word status.
In the above program the instrument is placed in remote
(line 10) and then programmed to perform the self test (line
20). The loop in line 30 creates a delay that allows the in-
strument to complete the test before going any further. The
instrument is then programmed to obtain and display the
status word (lines 40-80). Byte 6 (B6) will flag the result
of the self test; this byte will be set to 1 if the self test fails.
4.10 TRANSLATOR MODE
The standard Translator software allows you to define your
own programming words in place of standard Keithley
device-dependent commands. One word can replace a
single command or a string of commands. For example,
the word SAMPLES could be used in place of NO;lOOO. In
a more complex example, the word SETUP1 could be used
in place of ROFlT3G4.
The Translator mode can also be used to emulate the com-
mand syntax of other manufacturers' products. For exam-
ple, Hewlett-Packard uses the command RA to place their
instruments in the autorange mode, while the Keithley
equivalent is RO. By using the Translator mode, a kind of
standard programmming language can be developed for
a number of different instruments on the bus.
The Translator mode uses a number of reserved words and
a special character, as summarized in Table 4-34. Note that
these words and character are reserved and cannot be used
as Translator words. In addition, the X (execute) character
cannot be used in a Translator word.

The commands associated with the Translator mode are

4.10.1 Defining Translator Words (ALIAS)
Translator words are defined with the ALIAS command
by including them in a programming string with the
desired device-dependent commands. This process can be
demonstrated by the example string below, which
translates the device-dependent command string FlROX in-
to SETUPl:
