This allows you to confirm the E5260/E5270 GPIB command operation on the front panel LCD although it makes the operation time longer.
Page 51: Status Byte
Programming Basics Status Byte Status Byte Status byte bits are turned off or on (0 or 1) to represent the instrument operation status. When you execute a serial poll, an external computer (controller) reads the contents of the status byte, and responds accordingly. When an unmasked status bit is set to “1”, the instrument sends an SRQ to the controller, causing the controller to perform an interrupt service routine.
Page 52 Programming Basics Status Byte Decimal Description Value Error Indicates whether any error has occurred. If an error occurred, this bit is set to “1”. It is set to “0” when the E5260/E5270 receives a serial poll, *RST, ERR?, CA, *TST?, *CAL?, DIAG? or device clear command. RQS (You cannot mask this bit.) Indicates whether an SRQ (Service Request) has occurred.
