Agilent Technologies manual Status Bit Definition Description, AGE1439STATUSREADVALID

		Agilent E1439 Programmer's Reference
		Functions listed alphabetically
Status Bit	Definition	Description
8	AGE1439_STATUS_READ_VALID	This flag is set whenever there is at least one valid 16-bit
		data word available to be read via the VME data register. Not
		valid when using the local bus data port.
9	AGE1439_STATUS_BLOCK_READY	This bit is set in continuous mode whenever the size of the
		data in the FIFO is equal to or greater than the block size
		register. Check this bit before reading data to insure that a
		block of data may be transferred without fear of running out
		of data, thereby holding up the Local bus or VME bus. This bit
		is set in block mode whenever the module has successfully
		taken a block size number of samples since the most recent
		trigger and is cleared when the block is read out, when force
		to Idle is asserted, or when the module is armed for another
		measurement.
10	AGE1439_STATUS_ARMED	This bit is set whenever the module is in the Trigger state, or
		is in the Arm state and has satisfied its pre-trigger
		requirements. When this bit is set, the module releases the
		VXI Sync line. Once all modules release the Sync line, then all
		modules go to the Trigger state.
11	AGE1439_STATUS_FIFO_OVERFLOW	FIFO Overflow: This bit set when the FIFO buffer overflows
		in continuous mode
12	AGE1439_STATUS_OVERLOAD	This bit is set whenever the ADC converts a sample that
		exceeds the range of the ADC. The bit is cleared when the
		Status register is read.
13	AGE1439_STATUS_ERROR_QUEUE	This bit is set whenever there is an error in the error queue. It
		is cleared when the error queue is empty
14	AGE1439_STATUS_MODID	A (1) in this field indicates that the module is not selected via
		the P2 MODID line. A (0) indicates that the module is
		selected by a high state on the P2 MODID line
15	AGE1439_STATUS_HARDWARE_SET	This bit is set when all commands are complete and the
		hardware has been set

Return Value

AGE1439_SUCCESS indicates that a function was successful.

Values other than AGE1439_SUCCESS indicate an error condition or other important status condition. To determine the error message, pass the return value to “age1439_error_message” on page 102.
