Обязательные команды IEEE 488.2
*OPC
Description The *OPC command makes synchronization
between the instrument and an external controller
possible. The *OPC command causes the
instrument to set bit 0 (Operation Complete) in the
Standard Event Status Register to the TRUE
(logic 1) state when the instrument completes all
pending operations. Detection of the Operation
Complete message can be accomplished by
continuous polling of the Standard Event Status
Register using the *ESR? common query
command. However, using a service request
eliminates the need to poll the Standard Event
Status Register thereby freeing the controller to
do other useful work.
Syntax *OPC
Parameter(s) None
