*OPC<br />
Signal When Operation Complete<br />
Syntax: *OPC<br />
Parameters: None<br />
Function:<br />
This command provides a means of synchronizing operations between the<br />
2832-C and the host. This command sets the Operation Complete bit (bit 0) of<br />
the Event Status register to 1 when all pending operations have completed.<br />
This bit will remain 1 until cleared by the *CLS command or the *ESR? query.<br />
This command can be used in conjunction with the *ESE and *SRE commands<br />
to cause a Service Request on the GPIB bus when all pending operations are<br />
complete. Once the *OPC command is received, it will not set the operation<br />
complete bit to 1 while any of the following operations are in progress:<br />
Single acquisition in progress<br />
Data store enabled with fixed data store buffer<br />
The meter is ranging<br />
Related Commands: *ESE, *ESE?, *ESR?, *OPC?, *SRE, *SRE?, *STB?, *WAI<br />
*OPC?<br />
Operation Complete Query<br />
Syntax: *OPC?<br />
Parameters: None<br />
Function:<br />
This query provides a means of synchronizing operations between the 2832-C<br />
and the host. This command generates a response when all pending operations<br />
have completed.<br />
When all pending operations are complete, this query will cause the Message<br />
Available bit (bit 4) of the Status Byte to be set because of the response<br />
generated. By enabling bit 4 of the Service Request Enable register (see<br />
*SRE), the *OPC? query can be used to cause a Service Request on the GPIB<br />
bus when all pending operations are complete.<br />
Once the *OPC? query is received, the response will not be generated while<br />
any of the following operations are in progress:<br />
Single acquisition in progress<br />
Data store enabled with fixed data store buffer<br />
The meter is ranging<br />
The *CLS or *RST commands, as well as a GPIB interface device clear, will<br />
cancel the operation complete query.<br />
Returns: 1<br />
The response is generated when all pending operations are complete.<br />
Related Commands: *OPC, *SRE, *SRE?, *STB?, *WAI<br />
