IEEE-488 PROGRAMMING
NOTES:
4.10.5 Purging Translator Words (FORGET)
1. If no Translator words exist in memory, nothing will be
transmitted when the word list is requested.
2. Only the Translator words themselves will be sent
following the LIST commands. The device-dependent
commands will not be included in the list.
3. The programmed terminator and EOI will be transmit-
ted at the end of the complete list sequence.
Translator words can be purged (erased) from memory by
using the reserved word FORGET. This command is sent
to the instrument in the usual manner, as in the examples
below.
NOTE
The DCL and SDC commands will also erase
Translator words from memory.
HP-85 Programming Example-Add the following lines to
the HP-85 programming example from paragraph 4.10.1 to
demonstrate the LIST command.
After adding the lines above to the previous program,
press the HP-85 RUN key and note that the Translator
words are listed on the CRT.
Model 8573 Programming Example-Add the lines below
to the Model 8573 programming example from paragraph
4.10.1 to demonstrate the use of the LIST command.

After adding the above lines, run the program and note
that the Translator words are displayed on the computer
CRT.
HP-85 Programming Example-Run the HP-85 example
program from paragraph 4.lO:l and then use the follow-
ing statement to purge Translator words from tnemory:
When the statement is cxccuted, the Translator words will
be purged from memory. The Translator word list can be
requested, as explained in paragraph 4.10.4, to verify that
the words are no longer in memory.
Model 6573 Programming Example-Run the Model 8573
programming cxamplc from paragraph 4.10.1 and the"
type in the following statement to purge Translator words
from memory:
When this statement is executed, the Translator words will
be purged from memory. The word list can bc obtained,
as described in paragraph 4.10.4, to verify that the words
are no longer present.
4.11 BUS DATA TRANSMISSION TIMES
The length of time it takes to get a reading from the in-
strument over the bus once it is triggered depends on a
variety of factors, including the programmed sampling rate
and measurement size, the selected math function, as well
as the trigger mode being used. Table 4-35 lists typical
times for a variety of different conditions. Where ap-
plicable, default operating conditions are listed in the table.
