IBASIC Under Computer
Control
1. If both the analyzer and the computer send SCPI commands at the same
time, the analyzer may not Enish the
IBASIC
command before executing
the computer’s command, or vice-versa. The programmer must ensure
that SCPI commands executed by
IBASIC
do not overlap with SCPI
commands sent from an external controller, otherwise the system may
deadlock. Synchronization between the analyzer and the controller must
be ensured. See “Synchronizing the Analyzer and a Controller” in the
supplement to the
HP Instrument BASIC User’s Handbook
for additional
information.
2. Both
IBASIC
(SelectCode
8) and the external controller (LAN or
SelectCode
7) share the same HP-IB status model (the same analyzer status bits go to
each). Be careful sending commands which affect status reporting, such as
*CLS,
STAT:PRES,
*RST,
etc.
