This technique requires less bus traffic than did looping on BUSY.
Service Request Method: Enable the OPC bit in the Device Event Status Enable
Register (DESER) and the Event Status Enable Register (ESER) using the DESE
and *ESE commands.
You can also enable service requests by setting the ESB bit in the Service Request
Enable Register (SRER) using the *SRE command. When the operation is
complete, a Service Request will be generated.
The same command sequence using the *OPC command for synchronization
looks like this
/* Set up conditional acquisition */
