IEEE 488.2 Required Commands
*OPC?
Description This query puts an ASCII 1 in the output queue when the
contents of the input queue has been processed.
Syntax *OPC?
Response “1”
Note The OPC? command is equivalent to the *OPC? command.
Both give the same result.
*RST
Description This command empties the step response list. It is only seen
when it is part of another multiple command. In the example
below, by adding this command after *IDN?, you will not be
able to access the answer. The *RST, in this instance, erases the
identification string. In addition, this command performs the
following operations:
➤ Returns to initial state before command is sent, and not
necessarily to previous settings.
➤ Forces the device to enter into an Operation Complete
Command Idle State (OCIS).
➤ Forces the device to enter into an Operation Complete
Query Active State (OQIS).
➤ Initializes previous responses unless there has been a
program message terminator preceded by an *RST.
Syntax *RST
Example *IDN?,*RST<NL>
