The TEST command invokes SelfĆTest diagnostics or Extended Diagnostic
execution. The TEST command without arguments initiates SelfĆTest diagĆ
nostics. The TEST command with argument XTND initiates Extended DiagĆ
nostics.
Refer to the CSA 803A and 11801B Programmer Manual for more information
on TEST and DIAG command syntax and usage.
The return of one of two event codes listed in Table 6Ć7 to the GPIB and
RSĆ232ĆC ports signals that diagnostic testing is complete.
TableĂ6Ć7:ăEvent Code Descriptions
Event Code Explanation
460 SelfĆTest or Extended Diagnostics were completed sucĆ
cessfully
394 SelfĆTest or Extended Diagnostics were completed and
failed
In either case, a GPIB/RSĆ232ĆC controller may obtain pass/fail information
through the DIAG? query.
The TEST command with argument MAN initiates the Extended Diagnostics
similarly to entering Extended Diagnostics through the front panel UTILITY
menu. The primary use of this command is to provide the remote operator a
convenient way of accessing the diagnostics through the normal RSĆ232ĆC
interface so that the operator can use the Diagnostic Terminal Mode to do
remote testing.
CAUTION
The TEST command with argument MAN violates normal GPIB
protocols in that, when used, the instrument becomes nonĆresponĆ
sive to further GPIB commands until normal operation is resumed.
