Operation Registers
Measuring (bit 4)
This bit is set when a new measurement starts and is cleared when complete.
Measurement Available (bit 8)
This bit is set when a new measurement started by the INITiate command has completed.
The bit is cleared when the FETCh? command is used to transfer the value to the output
buffer.
The following commands are used to access these registers:
STATus:OPERation:CONDition?
Query the Operation Condition Register. The instrument returns a binary-weighted decimal
value representing the bits set in the condition register.
STATus:OPERation:EVENt?
Query the Operation Event Register. The instrument returns a binary-weighted decimal value
representing the bits set in the event register, and clears it.
STATus:OPERation:ENABle <enable value>
Enable bits in the Operation Enable Register. The selected bits are then reported to the Status
Byte.
STATus:OPERation:ENABle?
Query the Operation Enable Register. The instrument returns a binary-weighted decimal
value representing the bits set in the enable register.
Status Byte Registers
The Status Byte Register contains summary bits from the Questionable Data, Standard Event and
Operation Registers, and also has a single bit reporting the Service Request function for IEEE.
The Service Request function allows the instrument to request service from the system controller.
If the same bit is set simultaneously in both the Status Byte Register and the Service Request
Enable Register, the RQS bit is set in the Status Byte Register and the SRQ (service request) bus
signal is asserted. In response to the Service Request, the controller will normally be instructed to
perform a serial poll sequence on all devices. The instrument returns its Status Byte with SRQ set
when it is polled. The action of reading the Status Byte via the serial poll clears RQS and negates
SRQ.
The following describes the Status Byte Register Messages.
