Details
The GPIB provides a status byte register to monitor instrument operation. Two bits of this register are
bit B0 (Data Ready) and bit B6 (RQS). After all programmed measurements are completed, the data
becomes ready for output and bit B0 (Data Ready) sets.
If service request for Data Ready is enabled, bit B6 (RQS) will also set when data is ready for output.
If service request for Data Ready is disabled, bit B6 will not set when data is ready.
