When using the GPIB interface, serial polling may be used to check the No Command bit
while operation is in progress. After the bit becomes set, the ERR bit may be checked to
verify successful completion of the command.
If the RS232 interface is used, or serial polling is not available, then the *STB ? and
*ESR ? status query commands may be used to query the Status Bytes. Since the DS360
processes one command at a time, the status query will not be processed until the
previous command is complete. Thus a response to the status query itself signals that the
previous operation is finished. The query response may then be checked for various
errors.
SRQ
The user may issue an user SRQ (service request) over the GPIB. Only one SRQ (user or
otherwise) can be active at a time; the host computer must acknowledge any pending
SRQ's before a new one is sent. Note that the user SRQ is in addition to the usual service
requests based on the unit's status. See the section on status bytes later in this chapter for
more information.
GET (Group Execute Trigger)
The GPIB command GET will have the same effect as a *TRG command. If the DS360 is
configured for a single triggered sweep or burst, then the GET bus command will trigger
a sweep or burst. If the DS360 is not configured for one these, the command will be
ignored.
