The SCPI standard specifies the "*OPC?" command (Operation complete query) which queries the instrument for its operative state. When all pending operations are complete, the instrument responds with a "1". Some manufacturers block before completing all operations and don't respond with anything and some of them respond with a "0". This function handles both cases uniformly. |
