Resolution for Symptom 2
The 2003RP has a limit on how fast it can process commands sent over the bus. When
developing an application program that controls the 2001RP AC source, this must be
considered. Specifically, if non-query commands (commands that don‟t wait for a response
such as output setup commands) are sent at too high a rate, the AC source may not be able
to process them. In that case, a –100 Command Error will be reported.
This condition may exist on both RS232 and GPIB interface modes and is more prone when
faster controllers are used to run the application software. To prevent this condition, it will be
necessary to space out successive commands using a 20 msec delay. Alternatively,
commands could be sent to other instruments in the same system to accomplish the same
result.
