The OPCEXtended command.

Description

This command sets or queries the behavior of OPC commands and queries. When enabled, operations referenced in the *OPC command description notify when their overlapped functionality has completed. When disabled, the operations notify as they have in the past (only once updated in the instrument state database).

Usage

Using the .query() method will send the OPCEXtended? query.
Using the .verify(value) method will send the OPCEXtended? query and raise an AssertionError if the returned value does not match value.
Using the .write(value) method will send the OPCEXtended value command.

SCPI Syntax

- OPCEXtended {ON|OFF|<NR1>}
- OPCEXtended?

Info

ON turns on extended OPC behavior.
OFF turns off extended OPC behavior.
<NR1> = 0 turns off extended OPC behavior; any other value turns on extended OPC behavior.
